@@WillCogley For that it would be nice if there would be enough room for servos in the glove so you cant close your hand in further if you hold something in VR
@@MHP3Gamer You don't really want servos as such for that. Mostly you want a braking mechanism. That's for safety reasons. - if it can actually apply force to your hand there's high risk of injury. If it can just resist your movement, that's different. But yeah, this would be pretty interesting for VR, since the usage is the same - you're controlling another hand remotely. The difference being that in VR, that hand is simulated, rather than a robotic hand. Though on a more basic level I wonder why no VR rig yet contains wrist tracking bracelets? If you can track hands (which you already sort of can with existing VR controllers), and wrists independently (position and rotation along one axis), you can use inverse kinematics to determine arm position quite accurately, which at the moment is nearly impossible to do reliably. (Of course, for body tracking really you'd want wrist, shoulder, chest, hip and ankle tracking at a minimum. You can cut corners by not tracking shoulders, since the chest and wrist tracking could infer other elements, and you could do partial tracking by ignoring all lower body tracking - but why has nobody tried yet? It doesn't seem overly complex, unlike a hand such as this one...)
The data glove looks really amazing.Here's some suggestions: 1.Reduce the number of the angle sensors on the glove.When you don't actually grasp an object,PIP and DIP will always flex simultaneously.It's not necessary to put sensor on DIP. 2.Put resin or hot glue on the solder joint.This can improve the strength of the solder joint. 3.Tied all the wires to your arm.This can reduce the force applied on the solder joint.
Thanks for the advice, I did use some epoxy around the solder joints, but number 3 is definitely something I should have done. Interesting about number 1 though, I did think about this for a while but I am able to flex at PIP without bending DIP, not sure if its actually useful for anything though.
I would also recommend hot glue for the solder joints. You could also add a small stress relief loop. This way just make one turn of the wire and put the hot glue on the loop. For the circuit board, I would strongly recommend making a real PCB. More reliable, cheap and fast. And little soldering ! Finally, use a Teensy ! Cheaper, faster, better documented, just plain better than Arduino while still being compatible.
And for linearising the potentiometer output vs the actual movement, you could make a look up table of values using your 3D model and hard code it in the MCU.
@@WillCogleyI'm sorry to sound so stupid, but I love your project and have been following a little of your progress for a long time. What is PIP and DIP? I think of DIP as dual in line package for through hole chips.
You could probably do something similar to the main arm for the control surfaces, with sheathed cables actuating a series of potentiometers mounted securely to a plate on the forearm, instead of having delicate electronics waving around in midair.
waw, 11oct 2018? how is this not popular? this is some new age/futuristic/remote control/work from home/shop/virtual reality/ stuff,right here. Dude this is so accessible tech, u unleashed the knowledge !
This is really impressive, and looks to work fairly well. You mentioned that you considered using flex sensors but that cost was too high for them to be practical for your stage of development. Did you see any of the info on diy flex sensors during your research? If you take conductive ink you can draw out a flex sensor on some thin flexible plastic, like what’s used for cheap folders in schools, and make a decent sensor. I’ve used one to control a servo and it moved pretty smoothly. If you can’t get conductive ink, you can make a quite reliable one out of acrylic paint, vinegar, and graphite powder. It might be something to consider if you decide to make a more simplified control glove.
Inspirational work, man. Really love the design language and the integrated functionality. Most similar design this cool aren't very functional, or just seem like extremely fragile when a closer look is taken. Very cool. Subbed and tracking.
The applications for the control glove in VR can be tremendous, especially if haptic feedback was added. Imagine how trippy it would feel to pick up a virtual rock and feel its shape and size.
I like the idea of combining this idea with space technologies too. Imagine a remote ion propulsion drone that could be used by astronauts to repair things like the iss, or in future expeditions on route to mars and eliminate the need for space walks. Even in a martian environment if and when we successfully get to mars. I’m not an engineer, or educated in the sciences but I can almost guarantee this would be a real problem solver where space travel is concerned. Love it.
Very cool project for sure. Just to put an alternative out there you could use a kinect sensor or a leap motion sensor (similar technology I believe) to get the input data if the glove ends up being problematic. Great thing about this is it doesn't suffer from occlusion issues the other sensors I mentioned would, but I think a couple of leap motion sensors at 45 degrees pointed up at your hand could get both sides.
Not a criticism, but you kept saying you'd want to fix cable management, so here are two ideas if you were to do something similar again in the future: 1. Instead of running power/gnd from the arduino to EVERY potentiometer you could have two big wires for power and ground going to the plastic ring around the wrist. Then from there you can split it off to each potentiometer. 2. look into enamel coated wire (usually used in motors) at least for the Power and ground, if not all three connections. I'm not sure how noisy that wire would be so maybe you could still use some stranded wire for the analog pin Anyway it was really impressive to watch! I stumbled upon your videos and I'm glad I did. This is a really impressive project. Even just making the glove would've been a feat on its own! Kudos to you
Very very very good project. I also plan for a while to realise a project like this, and this is a good Inspiration. Thank You for sharing your experience
Coming here from a VR controller binge watching marathon... I just love the mini arms straddling each finger joint it's such a sleek design! Ever got anywhere with introducing this into a vr system? I think a robust ratchet mechanism on the back of the tiny arms with a braking mechanism wouldn't take as much space and keep your awesome design
nicely done though a few things to keep in mind are: 1. the more you ty down wires the less stress on the solder joints. I recommend tying down with tyraps with plenty of slack on the cable 2. for the movement of the base of the thumb and pinky, why not use a linear variable resister as that is kind of think you want to know. how much did it move of the plane of the hand. 3. you could lose the finger tip potentiomitor on all fingers except the thumb and move that at the next joint in the finger, as I don't think very many people can move the tip of the finger without the second joint moving as well. 4. learn your 3D printer so you can design better with less parts and a higher part strength.
instead of epoxy to secure weak wire joints, I recommend using ABS filament being extruded out of a 3d pen. This is nice and sticky for most surfaces and dries very hard almost immediately and would cleave to the wires and surface you are mechanically securing the wires to. is faster than epoxy due to it instantly hardening as it cools
The latest videos are from 4 years ago. Recently we have been able to control bionics with our nueral outputs easily, so I think this design could be a very beneficial design right now.
For mounting the potentiometers i would make a little pcb boards for each pot with wire-to-board connector. That should take care of the stress on the wires.
An idea for the thumb: maybe you could track it using hall sensors and neodymium magnets in each "plastic rib" in order to map the distance and relative angle with the next rib, and use the pots with the final thumb part. Also have another idea to implement haptic feed.
I feel like it'd have been easier to use multiple cameras and a black glove with white dots to track the position of each finger section and use that for calculating joint angles and the like. However, many props to the engineering job on control glove. It'd be super useful for VR games.
And this is our world guys. Inventors has only 20k subscribers, while youtubers who farts into the microphones or make pranks by throwing eggs into people have millions of subscribers
You did an exceptional job on this, especially to do it in a year including having to learn Blender and Unity. As for the solder issue, do you have space for a small strain-relief bridge clamp on the side of each joint, similar to what we have in UK mains plugs? And as for the noise you were experiencing, you might be able to filter it a little bit with a smallish capacitor on each signal as it goes into the multiplexer, forming a low-pass filter.
Thanks Stu, I definitely think it could do with a clamp on the side as you say, great idea. And thanks for the suggestion about the capacitor, I tried using an arduino program to smooth the signal but that seems like a much better solution.
You can use lead solder instead of lead-free. It is a lot less brittle but it is toxic so I would recommend wearing a proper filtration mask, safety glasses, and even a hood while soldering it. You could also try sanding and prepping the mating surfaces of the potentiometer and glove to improve the overall strength of their bond if you haven't already.
the stranded wires break that are near the solder joint, not the solder joint itself. heat stress and being so near to an unbending section of wire causes it to break right next to the solder joint. So changing solder type is irrelevant
To reduce noise, you could use twisted pair wires. You'll lose some flexibility (unless you use thinner wires) but could significantly reduce crosstalk
By the way, have you considered displacing the potentiometers through the use of cables? There'd be a lot less difficulty wiring them if they didn't have to be so near to the joints, nor would they have to be quite so small, and the hand structure in general would be less bulky. I'm sure there's downsides to the concept, but it seems like it'd make the construction less complex, and mean the actual wiring doesn't need to flex so much, the pots can be larger, and so on. (it would mean most of the electronics being on the forearm) - obviously this is similar to how a hand is connected via tendons with the actual muscles being in the forearm, but it may also be viable for the sensors themselves... my first inclination for this would be to use high strength fishing line, but there may be better choices...
But what i like most about your design is that it lends itself well to HAPTIC feedback. Since you're using a mechanism to measure the angle, you can also DRIVE that mechanism to force your fingers to move. Tho i guess you'd need to replace the cable-pulls on your thumb sensors with something hard... Or perhaps just have a spring pulling the thumb towards your other fingers (and the active motor will counter this movement).
I'm doing the same thing! Except that my robot hand will have actual tendons, like a real hand. The power comes from the "forearm". Great designs! I'd like to discuss licensing your work to build upon it.
this is exactly what i want to build to use my exo as i will be using extensions as to keep strength in the whole system and avoid hooks for hands of the system
Dude nice glove. I got an idea for you. Free one. Attach wires to each mechanical part tighten to it there. It will reduce stress of the potentiometer. There for stronger materials on the mechanical parts will longer time spam of life of the gadget.
you can also try and use leapmotion alongside the hand glove so that way you can gain more software accuracy because leapmotion has done a really good job on building software only based hand movement, not so sure about the thumb but i bet you could use it for like way better approximations of the data received from the glove, all in all man you've smashed it with this project. absolutely loving it.
Dude, you need some relief points for those wires; a peg or something to wind a bit of wire around--or to just secure it in place, so you can have extra slack--before the solder points, assuming there's enough flexibility in the wires and enough space to do so.
use small piece of PCB to solder the potentiometer to and solder the wires to that PCB so the PCB takes the stress and the plastic parts reinforce it instead of the small solder joints taking the load
It would be interesting to see if you can use something like a motion capture glove, similar to the costumes used in movie production to create CGI with quite natural motion. It's probable you lose some characteristics, like a bit of accuracy and definitely zero pressure/force feedback, but it's possible you gain a few extra degrees of freedom. I'm no expert by any means, it's just an idea.
what i suggest for the wire is to put a hole for them to be maintained in place using epoxy, if you can't block the contact, then block (begining of) the wire
I really love what you made with this project ! Have you tried to use a flex sensor on the glove instead of the angle sensor ? It coud save a lot of place, but I'm not sure it can be accurate enought for this kind of needs.
I wish you had a walkthrough video making one with all the components😭 I want to make a (muscle controlled) bionic hand with 3D printed parts but I’m new to this kind of stuff
I understand the need for mechanical components on the robot hand (obviously it's not going to work without them!), but to just read the position of a human hand, have you considered just using a kinect? (They're like $20 on ebay.) Also, today (a year later from your video) you can pickup an Oculus Quest and use the built in hands tracking, there is a native Unity SDK and you can get the hand position as an array of "bones" (Basically connected vertices). The accuracy isn't bad either.
Would creating a female electrical socket for the potentiometer work? I envision something that you could plug the potentiometer into before you attach to the joint. Just to change the orientation of the contacts so movement would cause less stress on the eventual soldering joints
Have you tinkered with the thumb pulleys? I recommend trying springs instead of the wire, more resistance should be a more sensitive reading... (Hypothetically... I'm new at this though...) LoL
Amazing! I have seen in other projects for prosthetics, that they do a mapping of movements with sensors in the forearm. Do you plan to integrate something like this in the future? Thank you very much, I look forward to the progress of your research.
what if we could use some of this to give some control to people who do not have full control of their hands either ? like instead of a prosthetic to replace the hand entirely but a muscle system to let a non functional hand move.
what do you use to fix the positions of the 3D parts on the gloves? I am curently working on a similar objects and have no idea how to stable the exo on the glove
Why don't you make a small PCB for the potentiometers, so the pots' leads don't break because the PCB would add strain relief. The pot signaling issue could be fixed by using encoders instead but there would be a lot more wiring, but the wires could be thinner as they'll be digital.
So clicking on this video I realized multiple things. There has been a certain lack of engineers focusing on replicating the full range of motion and replication of the human hand. There are lots of people focusing on prosthetic but why not replication. Even robotics like Boston robotics, they are pursuing it differently. but You Sr. are going with replication. If you get the hands down, you can then go to arms, then legs, hips and everything else. then climb into a avatar controller and there we go! a fully functional robotic avatar. and the easiest way to give the avatar controller a since of balance would be like Pacific Rim. just climb in!
really no, just code it, so it can work along side of you and you don't have to pilot it. piloting a robot is inefficient and a waste of time when it can pilot itself
how did you get the right dimensions for the model to fit your hand ? I have problems modeling a bionic hand that has the correct proportional dimensions and curves that would fit
i dont know which CAD prgramm you use but maybe you could write a small skript to take the movment of the glove an feed them into a Rig of a human hand
Could you send me the stl file for the control glove prototype? I want to make my own because I would also like to control a prosthetic using potentiometers, and your design looks cool. Thanks for considering my request!
Have you considered use camera or sensor to track the hand instead. Because the next big engineering challenge is tracking the thumb rotation as it move so using sensor to track the thumb position and rotation will be much more easier than pure mechanical tracking.
there is no point to work on tracking more since it is only for testing as a input method instead of hand coding the robot hand to move on its own with no input. will already has a working solution so why make another solution?
Very impressive! I'm making a control glove as well, though much more simple (for biomimetic bird wings, rather than hands). Do you have any ideas for how to measure wrist twist? I'm currently using two BNO055 absolute orientation sensors, one on the forearm and one on the back of the hand, to measure wrist twist and bend (transform hand quaternion by inverse of forearm, then convert to euler angles). It works pretty well and is sleek and durable, but these sensors are a bit iffy in terms of maintaining calibration while moving around a lot. It's also not super accurate since the back of the hand tends to wrinkle up when the wrist is bent upward, which lifts the sensor away from the skin at random angles.
I've never seen this video before, and yet, I spent 3 months developing literally the same project and same design, that's crazy 😂 tho yours lokks cooler
so amazing project , the way it look , the way you design it , awesome . can you tell me what is your study field , mechatronic bachelor ? which university :)
Love this, really impressive! Though I would've thought that with the rate of progress being made in computer vision, you might not even need a physical "glove" soon?
I've been diving into engineering science for the past 4 days, it's amazing how much you can learn on the internet.
If you will place it on kick starter as vr glove, I would like to get one pair!

I wish you had a walkthrough video making one with all the components😭 I want to make a (muscle controlled) bionic hand with 3D printed parts but I’m new to this kind of stuff
I understand the need for mechanical components on the robot hand (obviously it's not going to work without them!), but to just read the position of a human hand, have you considered just using a kinect? (They're like $20 on ebay.) Also, today (a year later from your video) you can pickup an Oculus Quest and use the built in hands
tracking, there is a native Unity SDK and you can get the hand position as an array of "bones" (Basically connected vertices). The accuracy isn't bad either.
Would creating a female electrical socket for the potentiometer work? I envision something that you could plug the potentiometer into before you attach to the joint. Just to change the orientation of the contacts so movement would cause less stress on the eventual soldering joints
Great! You know my dream is make a robot hand that have flexibility. This is a great concept.
Have you tinkered with the thumb pulleys? I recommend trying springs instead of the wire, more resistance should be a more sensitive reading... (Hypothetically... I'm new at this though...) LoL
I haven't seen anyone comment this but that transition tho @0:01 damn that was nice
Amazing!
I have seen in other projects for prosthetics, that they do a mapping of movements with sensors in the forearm. Do you plan to integrate something like this in the future? Thank you very much, I look forward to the progress of your research.
what if we could use some of this to give some control to people who do not have full control of their hands either ? like instead of a prosthetic to replace the hand entirely but a muscle system to let a non functional hand move.
at ~17:40- the end.. is it just me or were you using a right hand glove to control a left hand model?
You can use pneumatic with lineal actuator with electrónic valeves so don't need servos
what do you use to fix the positions of the 3D parts on the gloves? I am curently working on a similar objects and have no idea how to stable the exo on the glove
Love to see people using blender!!
Why don't you make a small PCB for the potentiometers, so the pots' leads don't break because the PCB would add strain relief.
The pot signaling issue could be fixed by using encoders instead but there would be a lot more wiring, but the wires could be thinner as they'll be digital.
This is exceptional stuff!!
I love using blender to prototype things like this. Looking forward to a stable 2.8 version.
Absolute Cool
So clicking on this video I realized multiple things.
There has been a certain lack of engineers focusing on replicating the full range of motion and replication of the human hand. There are lots of people focusing on prosthetic but why not replication. Even robotics like Boston robotics, they are pursuing it differently.
but You Sr. are going with replication. If you get the hands down, you can then go to arms, then legs, hips and everything else.
then climb into a avatar controller and there we go! a fully functional robotic avatar. and the easiest way to give the avatar controller a since of balance would be like Pacific Rim. just climb in!
really no, just code it, so it can work along side of you and you don't have to pilot it. piloting a robot is inefficient and a waste of time when it can pilot itself
Hi, fantastic project! Is it an open platform and if yet have you published on thingiverse or something else?
I think he's waiting for it to become 100% working
how did you get the right dimensions for the model to fit your hand ? I have problems modeling a bionic hand that has the correct proportional dimensions and curves that would fit
Hey cool project hope this makes it for further practical use into market.
Also what is the PN of the pots you used? looks quite neat.
i dont know which CAD prgramm you use but maybe you could write a small skript to take the movment of the glove an feed them into a Rig of a human hand
Could you send me the stl file for the control glove prototype? I want to make my own because I would also like to control a prosthetic using potentiometers, and your design looks cool. Thanks for considering my request!
Wouldn't the remote interface be easier and more reliable with a camera and a dotted glove used in motion capture? Love the robotic hand!
2 cams for depth
forearm mounted one cam on top viewing hand and wrist movement and another on the bottom to aid in accuracy.
Have you considered use camera or sensor to track the hand instead. Because the next big engineering challenge is tracking the thumb rotation as it move so using sensor to track the thumb position and rotation will be much more easier than pure mechanical tracking.
there is no point to work on tracking more since it is only for testing as a input method instead of hand coding the robot hand to move on its own with no input. will already has a working solution so why make another solution?
Is it possible to make less than 10 types of set of gloves and hands to suit most variety sizes of human hands including different ages persons.
Very impressive! I'm making a control glove as well, though much more simple (for biomimetic bird wings, rather than hands). Do you have any ideas for how to measure wrist twist? I'm currently using two BNO055 absolute orientation sensors, one on the forearm and one on the back of the hand, to measure wrist twist and bend (transform hand quaternion by inverse of forearm, then convert to euler angles). It works pretty well and is sleek and durable, but these sensors are a bit iffy in terms of maintaining calibration while moving around a lot. It's also not super accurate since the back of the hand tends to wrinkle up when the wrist is bent upward, which lifts the sensor away from the skin at random angles.
What if you used the kind of sensers that vr controllers use and have a box with a bunch of cameras in it to pick up all of the sensers
Awesome design.😀
Have you considered using a Leap Motion?
Minha idéia também era assim, mas, com menos sensores e mais molas
Salut Will,
Impressive work!
What program do you use to get the sketchy 3d schematics?
Salut! Thanks, I used Solidworks for all the CAD, if you're referring to the diagrams from 0:38 to 1:59 they are my drawings
I've never seen this video before, and yet, I spent 3 months developing literally the same project and same design, that's crazy 😂 tho yours lokks cooler
You're a God.
so amazing project , the way it look , the way you design it , awesome .
can you tell me what is your study field , mechatronic bachelor ? which university :)
great work!! keep it up, bro.
Love this, really impressive! Though I would've thought that with the rate of progress being made in computer vision, you might not even need a physical "glove" soon?
What's the part number of the surface-mounted potentiometer?
this glove could be the future of vr
Yes and it not just VR (future).
Use thin silicone wire, 30awg or so, it is much more flexible than wire you're using
how long did you take to make this??? This is great, you have a Fan here :3
Amazing brother! Would love to work with you sometime!
What program did you use to do the renders ? I am fascinated by them.
