For the thermal switches, you can easily put an LED with a resistor in parallel with each thermal switch. If a switch trips, the appropriate led is going to illuminate, so you can find which thermal switch tripped.
Nice clean looking build. I've become quite partial to timing belt actuators to avoid the high backlash from 3D printed gear actuators. When properly tensioned, timing belt actuators have essentially no backlash, and only a little deflection under load from belt stretch. With some gravity compensation on the shoulder joint, you could also get away with a lower gear reduction.
TIP for Everyone, if you print hollow shells; you can pack them with glass-resin, to save time and increase strength ! Amazing build, love the custom driver stacks too !
I think you're doing a good thing by pushing forward 3d printed actuators. Backlash could be too much for precise applications, but that's to be expected
Incredible project! Great work! Thanks for your contribution on the 3d printing and diy Robotics community! I hope that you get the recognition and exposure that your content deserved
I would have really loved to watch you solder those motor drivers and the Teensy. Those boards were pristine! I would definitely watch a soldering tutorial from you!
Holy crap that's glorious! Would 5 axis be good for getting cool shots with a camera? My brain sucks at figuring out the potential movement paths lol. If it is then a cool idea might be the ability to add keyframes for setting up a movement path. Maybe a rotary encoder to first dial in how many keyframes you want, then a button to set a keyframe, and a little display to show you how many keyframes are left to set as you enter them.
Two ladders or a few 2x4's of wood, with rails on the sides of them to create a x and y axis, with a spray painter on it. You can place it against a wall like a ladder normally would, and hit PRINT, and it either coats the entire wall in controlled even passes, or draws a photo painting from a file you send the gcode. Cost? could only be just a few dollars if anything, if you already have the basic materials. Use it to become a tireless exterior interior wall painting employee that you only pay with buckets of fresh paint.
Thank you for the backlash segment of the video and upcoming joint testing! Great job putting this together, I will definitely be watching the upcoming videos on the further testing/design iterations! One idea that hasn't been addressed with 3D printed gears on youtube (yet) is applying a wear coating to the gears (something like a low-friction paint) - to allow tighter tolerances for less backlash without significantly increased wear rates. I think this, combined with grease, would be a really interesting long-term test after the upcoming individual joint/force/wear tests!
super-cool! So glad to see you doing affordable projects ... the videos with expensive drives have unmotivated me recently- but I think I'll be joining your patreon now! great work! thanks!
Awesome, watched all the way through. You go through some PLA, sir! Guessing you're not buying it 1kg at a time, maybe those 5kg texas spools? Now if you can just flip the arm upside down and make it self-balancing, and put your eyeball on top of it! :)
Recently found this. Im thinking mounting it to my ceiling and using it to grab nuts/bolts kind of thing for me. Would be cool to us AI voice actuated to initiate the part pull.
This is just awesome! This summer I would like to make a project like this with your STL files, but the electronic parts seems rather big for a beginner. Would you suggest a small project to start with?
Check out Michael Klements DIY camera slider, I'm currently working on one for my first project and it's got a lot of the same DNA as a build like this robot arm.
you know... I may have to sub to your patreon to get those files... im curious how well they'd do in ABS (i don't print PLA, ONLY abs and petg) or if I mill them with the cnc in aluminum... might be nice to have a robot arm in the workshop to hold things for me while I weld. lol
Without screw and nuts it cost around 150$ (if you use cheaper drivers from 3d printer). Each motor is less than 10$, all the bearings is less than 40$. And you can get stepper driver for less than 10$ per driver (I use here more expensive drivers 20$ per driver).
I am not stepped back. I still plan to use BLDC. But BLDC controllers way more expensive than stepper controller (around 100$ for BLDC vs around 12-20$ for stepper). So with BLDC, 5 axis arm would cost 500$ only for electronics. So to keep everything cheap (as many of my viewer require) I used steppers. But I have several BLDC projects on which I am working now.
@@Skyentific Glad to hear that, but I also noticed the price of the controllers, and I even bought a very "cheap" Odrive clone on aliexpress... Great projects, thanks for your work!
Dude, if you're going to say they are powerful then specify that in WATTS. Volts x Amps. Now You have me wondering what they can actually do. NEMA23 is simply a mounting size specification.
did you try first before going to change the motor just jank up the current? or did you just stick to a recommended value (will make the driver and motor hotter ofc and need active cooling for driver possibly and all of that..)
А какой софт можно использовать для работы такого манипулятора скажем в покраске или положить переместить деталь? вопрос не изучал, просто поразила проделанная работа на вашем канале.
Super nice Robot ❤ You did a bad job of inserting the music into the video, the fade from loud to off is way too hard and annoying. Instead, turn it down a bit when you speak but not off.
Can't you do a cascade chain of resistors down the serial wire? and instead of actually "turning off" the devices physically just run one more wire that carries the effective (enhanced) resistance of the "Distance" to each sensor. Basically a detectable resistor ladder, then do some logic to decide "what happened, where and when". Seems like a single pin might be able to manage that? maybe I'm being stupid. You could just leave in place what you have and maybe figure out "how far up the sensor wire the break happens" or something, eh you are the genius, details left as an exercise for a greater mind.
I’d forgotten about this technique. I believe it is, or was, commonly used in car steering wheel controls and the remote controls that were common on Walkman and MiniDisc headphone remotes.
@@Skyentific да я без осуждения же) просто неоднократно на вас натыкаюсь и все гадал русский у вас родной или все таки что то другое замешано) успехов вам!
Old prusament on the table. What happened to open source man. Anyway its not like normal people can afford to build it it's hard to be a volunteer and try to get a robot arm club going without a frame of reference. Not everyone can do all things
Where is the problem? Its minimal version parts cost is around 150 USD. I don’t know how to go cheaper than this. It is not open source yet, as my channel does not grow. So I have to use Patreon. And on Patreon you get this design for 10 USD. Even with Patreon my total income is 1/3 of the minimal wage. So right now I cannot afford to go open source. It is 1M youtube channels which can easily earn enough money only from youtube ads. And they can do open source. In my case, from youtube ads I earn almost nothing.
@Skyentific ok. I'm sorry. Can I give you a 1 time donation for plans of this arm. I apologize I was frustrated. I'm retired at 44 with ptsd but I have an engineering degree I never used and I went into policing instead. I'm paying for the materials and have accumulated a bunch of stuff to build an arm for the kids. I completely understand you need to make money. I have friends with much smaller channels. I can't afford the 5160s but I'll use different drivers. I think you're incredible. I can code and do electronics but I can't model in 3d to save my life. I will give you any amount you think is fair. Again I'm humbly sorry. I volunteer to teach programs and that entails buying all the parts for everyone. I feel it would be disrespectful to join your patreon for a month just to have access to the plans. I can only afford to build robots with nema motors. I can manage the coding if you don't want to share it. Thank you, even if you don't.
Hello skyentific! I building a actuator based on innfos gluon congratulations, can you recommend any cheap motor that I can buy which can apply to the actuator to have the final result as innfos gluon? (it's using redution rate of 36:1), I also send you message on instagram
It looks very nice. The PCB tower looks cool but, I am afraid that the motor drivers are going to get hot, maybe heat-sinks should be added and a fan for the enclosed space. Backlash seems quite high, but I'm waiting for the next video with more advanced movements to see how much it oscillate when it moves.
I'm trying to print a robot arm, there a couples design around, i wonder this is better or the moveo that everyone seem to be printing the moveo cost around $600 -700 buck to build. This seem look to be much cheaper at $150. There also some harmonics drive that is gaining traction's, very exciting.
Hello mr. @skyentific, do you plan to do a tutorial on inverse kinematics and trajectory planning on this robot? There is not a step by step tutorial on youtube about these topics, especially on 5 dofs robotic arms, you could be the first one
With the metal acting as a thermal mass, it might still melt if the melt temp is reached on the motor. If you set threshold lower, then it will take a long time to turn back on. It seems like eventually you'd use the thermal switch as a failsafe only and calculate the safe duty cycle which would always be in effect?
Hohoho i like your laugh! Also i just finished printing an arm that uses servos, next time I'll try with steppers, great video as always, I'll check your cad and code, also can you give us a tutorial on how you do inverse and forward kinematics, looking forward to it!
The problems I have found with lever switches is that they are too flexible. Maybe imprecise? Reed switch, may be better, but a photo switch can be rather precise. Many outdated automotive switches available.
Can you suggest me an encoder for my clg project where do a arm exoskeleton I have selected a higher torque dc motor From automobile wipers . Now I like to control its position very precise and accurate but I need encoder which will be flat and small as I don't have enough space to mount normal rotary incremental encoder which are in shape of small motor Range of motion 180 Speed- 30 rpm max
What are those green wire connectors called guys. I have some but when I search I just get the normal ones. I'm building it and donating it to the local non-profit makerspace I volunteer at. I've paid for all of it and it's not expensive if you take your time and order the parts a few at a time. I'm going to paint the grey pla. I've done it before and it looks like metal

Who would have thought that Tom Selleck is into 3d printing and robotics.
Awesome video as always. Aldo you print the parts at home or do you send them to a tied party printer company?
Thank you! I print all at home. I have 3 printers. Two with 0.4mm nozzle for prints where I need quality and one with 0.8mm nozzle for big parts.
so awesome! This is the future!
Awesome, watched all the way through. You go through some PLA, sir! Guessing you're not buying it 1kg at a time, maybe those 5kg texas spools?

nice job!
damn... mine sux next to this one. also i wanted to use xbox joystick but i decided to create one from the arduino joysticks
let me speak from my heart
Can’t wait
This is an awesome build. Great work!
So do you think for your next project you can get this arm to be a 3D printer that prints non planar?
Where can I get the JLCPCB Files. I want to build this exact tower!! I am happy to pay, please point me to the files!!

It would be super complicated to mill the gears. But PETG should work.
Напишите пожалуйста какая себестоимость получилась по компонентам?
Awesome.
How do you keep the aluminum links fixed on the table? Drilled? Suction cup mounts?
How much does it cost all together? Even a rough estimate would be nice.
Without screw and nuts it cost around 150$ (if you use cheaper drivers from 3d printer). Each motor is less than 10$, all the bearings is less than 40$. And you can get stepper driver for less than 10$ per driver (I use here more expensive drivers 20$ per driver).

действительно молодец, интересный проект, теперь пора переходить к стоящему, ну хотя бы для манипулятора-сварки....многие спасибо скажут
Is there a video on using the robot with python and pi?
Is there a reason you stepped back from using BLDC and stepped towards stepper motors?
I am not stepped back. I still plan to use BLDC. But BLDC controllers way more expensive than stepper controller (around 100$ for BLDC vs around 12-20$ for stepper). So with BLDC, 5 axis arm would cost 500$ only for electronics. So to keep everything cheap (as many of my viewer require) I used steppers.
