Looking cool, i love how you design all your own `mechanics and use different electronics to achieve such cool effects. This project is really coming along and i hope once its finished you'll be able to drive it all over the convention floors and amaze everyone.
The droid will be so cute being able to move its head from side to side!
This is looking really good, can't wait for the next one!
Videos like this inspire me I'm 14 and I'm going to make one!
Really clever head movement mechanism, bloody awesome
I am learning Arduino and when ever I get stuck on some code I watch your videos to regain my motivation. The BB-8 version 2 is a prime example of the amazing things you can do with micro controllers and a bit of code. Keep up the good work James.
James, you are the master. Another great project and showcase for your problem solving skills. A superior intellect indeed!
Man you are a legend! Awesome work!
Love it keeps getting better and better
Fantastic work! Your research and design in this project is impressive, and I like how you show, and explain to us what it is that you're doing and working with!
Really love this project James; I've been thinking of supporting your Patreon for a while now and this has pushed me over the edge.
This is very impressive work! Not the type of thing I generally watch all the way through, only because of it's complexity, but you truly made it captivating. So much so that I subscribed to see this thing through. Also enjoyed the concept of the ball balancing project. It's what lead me here. You're fueling future endeavors for sure. I can already imagine where this could lead. Great job, James!!
This is absolutely fascinating. Really cool series. Well done Good Sir.
This is really great, love to watch your progress! :)
Stunning
I'm blown away with how much your work has progressed. It's been enjoyable even though I'm terrible at robotics.
i cnat wait util this is done, it looks so cool!
This is looking really cool and coming along great. You're such an inventive person and I love seeing what you come up with. Keep on rolling!
I had the same idea for build when I saw your BB8!! your channel is the best!
you are a genius sir,i am amazed everytime!
Ingenious. Love your work.
Excellent work!! This is much more like the inner workings of BB8 as I imagined them back when he was rolled onto stage - though of course I'm not anywhere near as good with electronics as yourself . I'd love to start building things like this, hopefully one day I'll have the spare money & some experience. :D
soo amazed by your engineering and crafting skills!! This project brings out all the best. :-D
Man I'm loving this project even more than the last bb-8. It's just amazing to see how everything i'm learning in collage right know being used in such a fun project. Hope I will be able to support you thru patreon in the future.
Excellent work
Looking forward to how you'd complete the outer parts (sides) of the circle plus the panels.... Thank you for this video, very educating and entertaining.
this is fantastic! I am really excited for when the ball is a complete sphere. :)
Looking good!
La fuerza es intensa en ti, joven James ;)
Sei un GENIO !
Great progress
Beautiful and inspired
James, you're the man. Watching these videos I wish I had any understanding of robotics and computers.
If you ever decide to sell a kit of just the robotic element in the ball I will spend an arm and a leg to get it.
Ovation to you James!!!! How is that you are not working in the special effect industry. Do you have any formal education in engineering? How did you reach to that level of ingenuity? I love your work!
this will look so cool when its done
Congratulations , you are my hero , I would take your resources to test my abilities , a hug from Ecuador
Killing it with this project.
R6 was previously my favorite of your projects, but BB-8 has surpassed even it. I can't wait to see what you come up with for the utility arms.
your a geniuses man i love your videos
This is coming along great. Looks like every issue already has a solution haha. It's going to be amazing to see it fully functional.
beautiful mechanism :D
When you are all done with this build I would love to see the V1 head try to balance on the V2 base!
James, You're the best ! It's a real pleasure to follow your incredible projects.
JJ Abrams should call you for the next Star Wars ;-)
wow !! very Cool !!
great job man that helps out alot
Your TH-cam channel is very inspiring! I hope one day I can create some of things you make!
I guess you can say this bb-8 is the head of the world
You are genius!!!
With the hulk buster suit, make a pivot joint for the ankles with a hole going from the top through to the bottom that you can put a pin through. It's the easiest way of making a locking pivot joint
YOUR SUCH A GENEOUSE JAMES BRUTON......XD!
wuauu friends is very very good proyect congratulation , felicidades amigo muy bien aparato :-)
I'm using your guides to design my own BB-8 project, and I've realised that electronic stability with wheels at the top is more effective than relying on weight at the bottom to stabilise it. I'm thinking that a four or eight omni-directional wheeled machine in the centre of the ball could work the best for moving the droid as it does in the movie, with no drift.
Wow! great work man, this is really coming together well, and fast! when do you even sleep? "nothing worse than a droid with a slow head"..words to live by haha.
the beggining explaination of the time just fucking blew my mind.
Hah! This is what I suggested in my reply to your first BB8 video. Obviously, you're the one who did all the hard work, but I'm happy you agreed my "pendulum drive, magnetic coupling" idea was the way to go, whether you got the idea from my comment or not.
Also, how can we learn your CAD/Printing techniques? Nice involutes on your gears- very smooth. Regarding stability, instead of coins, put a LOT of mass on your pendulum/reaction wheel. Mass is your friend there.
genious!
Having a variant of the BB 8 with the tire body shape it has here would look really cool actually.
***** I'd love to see that. This looks really cool as it is now.
Awesome
Good , thank!
Great !!!
I admire what you are doing here but you seem to have a talent for over complicating a simple problem.
James, like @SoarPilot mentioned, you should integrate dual gyroscopes to stabilize your movement. Look up a Lit C-1. It's a self stabilized motorcycle that doesn't fall down even in a crash.
awesome
Have you thought gyros to stabilise side-to-side wobbling?
Using that technology, you could make a Gyrosphere from Jurassic World!
Great work so far! I have a question though. Exactly what are you planning to do to create the sphere at the bottom of BB-8 and how will it work? I have a suggestion that may work and make the sphere look good. What if you encased the drive wheel in some sort of thin, spherical casing so that the drive wheel is completely covered and looks like a solid sphere while keeping functionality. since the head is held on by the magnetic thing, it could easily go on top of this said casing and still work perfectly.
cool bb8
i think wobbly head movement adds more of an atmosphere for BB. he is wobbly in the movie.
You should make a darth vader cosplay it would go along great with your DIY lightsaber :D
I wondered how you'd top the R-6. It's awe inspiring.
+James Bruton (XRobots) I remember when you were sliding the hulkbuster head mechanism, up and down repeatedly whilst staring. The look of inspiration was apparent as you stated (paraphrased) "I can make a droid frame this way !!!"
I think the best way to counter the wobble would be to rely less on the head's mass (which is high up and ultimately not all that heavy, going by the way you've designed it so far) and use a motorized pendulum that can manipulate a mass on a motor-driven pendulum with a lower center-of-gravity. This is more or less what you tried with the other BB-8 by using ball-bearings and water, but the issues with those is that there's no control over those, where-as with an actuated pendulum you could fine-tune it to your heart's content. You've already more-or-less done this by having the fly-wheel assembly adjust itself to compensate for some wobbling, but I think a separate pendulum assembly would offer a more fine-tuned control scheme. (just my 2 cents)
Keep up the good work!
I think you ought to consider doing BB-8 a bit like your R6 droid where it's open on the sides but still having the pop out mechanical arms and what nots. It would be a crying shame/crime to cover up all of those internal workings, they're a piece of art in themselves. ;)
Also, have you considered the space below the rotating "coin ring" for help with counter balancing BB-8, or is there insufficient space in that area?
Anyway, loving the progress so far, James, keep it coming!! :D
*****
Ok, cool. I understand about the head movement thing, just thought having one where the head doesn't move side to side so much would be pretty neat, too. Not to worry, it'll be awesome without him showing his insides to every Tom, Dick and Harry at conventions.
Glad to hear about the lead weights. I saw that part near the end and wondered if there was any electronic method to doing it.but as it turns out, some good ol' fashioned heavy weights should work just as well. ;)
How would you actually overcome the issue with the magnetic interference? Does the IMU let you enable/disable each type of measurement separately or are you stuck with all three types merged? The only other thing I could think of doing would be to create some sort of concrete or plaster ring rather than using the coins.
It's awesome, and i got idea you should put gopro or another camera in the sensor ,,eye".
You should triple the magnets and add shock absorbers to the casters or it's going to shake all the time. I've seen something similar and it shook all the time.
He's a goddamned timetraveler. O_o
I know this comment is very late to the party, what with these being shot and released after the fact, but have you considered an off-center weight in the head to compensate for side to side motion? Rather than moving the whole head side to side to dampen your wobble you could rotate the head allowing for a much quicker reaction time. (disclaimer: I have no idea if this would work at all)
Oh, and your videos are fantastic, thanks!
right now you have a mobile part on the inside which you use as a weight to go to either the front or the back, with a turnable ring with weights to spin. have you ever considered to make the entire rails which you use to move the weight from front to back turnable? like a circle in a circle. i don't know how to explain it really, but i could rever to a machine they use in austronaut training to prepare for 0G. a seat in a bunch of move able inner rings which are all move-able on their own axes. but instead of a seat in the center, the right you have right now?
a gyro?
hey james did you get one of those bb-8 sphero toys? they are so cute
16:45 genius!
James... Could you please, as an extra video, try to put your BB8 robot-head (the 1st bb8 you made) inside of a styrofoam hemisphere, just to see if you can control its wobble?
You should try to make a C3PO. I think that would be cool.If you want to.
whats really cool is you made it.
with regards to the head and its wheels it uses to move on the ball, have you thought about using (for lack of a better word) 'roller wheel ball'? googling the text brings up what I'm referring to, which is basically a large ball bearing trapped in a casing that is allowed to roll in any direction.
I could see this may benefit the head when rotating or changing direction by making it more stable.
(great channel by the way, really enjoying it)
looks, great! wish i had a 3d printer...
Hi, you said in one Video you are not considereing to use a sphere-bearing for the head-wheels, because of the noise it would make. Can´t you use instead the rubbery material for the sphere to elimate the struggle against the current wheels turning its direction. Alternatively use a steel sphere-bearing and coat the whole ball with latex to give it a softer surface (also would have more grip on sleek ground). Nice to see this interesting projects.
That is cool whats it made out of plz tell me.
Absolutely looking fantastic James! but I want to ask, how are you going to make this into a sphere?
+James Bruton (XRobots) Lol I guess it was an obvious answer, but what I really mean't to ask, (and it really was my fault for not elaborating enough) will it be able to rotate on all axis, like the sphero toy? Or will it just be able to go back and fourth and move the head shell slightly?
Thanks again! and keep up the great work! ;D
Great video, although I got some minor headaches from the designing aspects (mostly caused cause im an engineer and perfectionist,which is a really dangerous combination :P ).
Here are some tips that you might want to use for this or later projects:
a) If you use ball bearings then please design the fitting hole to be a bit smaller then the bearing, you can use a vice to press fit the bearings into the print => no nuts needed
b) use helical or heringborne gears to eliminate the possibility of them missaligning.
c) consider IGUS bushings and so on if you have parts which cause plastic to slide on plastic or metal
d) You could've designed the larger gear to have it's clamping hole for the M6 rod to have a hole that's 5,2-5,5mm in diameter, that way you could screw in the threaded rod into the gear which could maybe even eliminate the need for the clamping ring.
e) if possible please replace the coins with cutted round metal rods which have the according diameter and length. The metal rod could cheaply be bought from ebay and you'd eliminate the creation of an magnetic field.
I know that there are often very less alternatives and in most times the alternatives are so timeconsuming, that you couldn't keep up with the video production. This is just a tiny guide of how you could improove the projects while keeping the video production going. I hope you can implement some of my ideas or comment on if you agree / disagree with me.
Hey James I know you busy with many projects now but for your next project could you build a Dalek ?
as in the characters who say "EXTERMINATE" in doctor who
Just curious. how are you attaching the outer parts of the ball?
+Pitch lock I assume ABS welding.
Where did you get the joystick stick (part) ?
You mentioned 2kg to 3D print the head ... what is the approximate mass of the frame/panels of the main sphere?
what do you think about the hulkbuster in the new york comic con video???
Fantastic! Just one thing: The servos are rated in the unit kgcm, kg·cm, not kg/cm.
you should make a droideka built off this concept..
and its interesting
how many versions of bb8 do you have now?
it's a pretty cool project, I think it's overly complicated for what its purpose is, unless that was the whole point of this, running 3/4 wheels on the inside of a ball would have been more stable than balancing the mech. even using mechanum wheels would provide any direction of travel then as you did for the head of the mk1 build.
always interesting projects though!!!
+James Bruton (XRobots) fair point!
I hope the build plays out how you imagine the end result. it's looking good & is a very different approach to the same complications of such a build. good luck dude!
where did you get the magnetd
Hi James, how did you separate the Globe? I have the same one, but can't get it apart and I don't really want to cut it with the dremmel ;)
James Bruton were you wearing your Iron-man suit!? ;) heh thanks.... I'll give it another go :)
