It's a small thing but I like that belt tensioner. No need for an adjustable mechanism when you can just print a new part for next to nothing. There's probably a bunch of other design paradigms that need to be updated for new technology like this.
@Badspot : There is a temptation to use a sliding or eccentric tensioner... my experience is that they could be a weak spot, and probably become a source of annoyance.
I don't know if this has been thought of or covered before, but an accelerometer to provide position feedback at the arm might allow it to compensate for all the compliance in the actuatror plus any flex in the beam.
wow, really nice structure overall. Maybe try to reinforce the top plate with a screwed or slotted profile... By the way, what would be the total cost to have it fully operating, considering controller and claw?
I already was a subscriber since your over engineering of the eye, truly fun to see all these things you are making and giving back to the community. If you have time please make a video on how you simulate your robots in Nvidia Isaac and how it differs from gazebo. Or the reason you jumped to shaprd CAD instead of fusion 360. What do you recommend us beginner Robotics fans to use. Personally I have used fusion 360, solidworks and inventor and sometimes shaprd on my ipad. But to be honest I like solidworks and inventor just a bit better. The other two work but just a bit different. Good luck with the raffle, I entered if I get it I will make youtube video on it and write blogs on how to run simple ros projects on it and also dip my toes into Isaac sim.
Great Channel but... I can't think of many/ (any?) diy robots that are very useful and easy to program for different task on a day to day basis. I made one simple one, but it's an easy task that i does and not critical. I think the hardware , though not easy, is easier than creating an interface for the user to accomplish useful tasks.
mhd true dc motor, ie radial current, two steel/metal surfaces, rolling ball bearings as the current pathway, vertical magnetic field below insulated, a thrust bearing socket on the bearings top side
8:50 yeaaaaa now i bet you're thinking back to how you said "wow this is heavy" earlier in the video. You apparently designed it WAY over-spec, and it should have been lighter.
