Thank you sir I enjoy your videos very much I'm 64 years of age I have traumatic brain injury and I'm retired it is easy for me to understand you I'd like to say thank you very much
@@Skyentific you just shine with happiness in this video, thank you for the interesting material. P S Do you plan to organize information on the various available electric drives in some form (table of comparative characteristics or something like that)?
It looks like the biggest difference in mechanics/drive system between these "hobby" type 5-6 DoF arms and "industrial" models is backlash. With 2mm of backlash it probably would be quite hard to use this arm for applications like welding or some precision positioning application. I think something similar but with much smaller backlash and "sane" price point would be a killer product.
Man. I already backed it but holy hell I am impressed with that. Dealing with the backlash can be solved with some clever locator methods so that's not even a deal breaker. I can't wait to have my hands on this and am so happy I skipped out on all the stepper motor versions of desktop robots.
Yeah man, nobody will tell you the absolute accuracy, you will always get the the accuracy in reference a teached point, fixed in space and known by the system, called Pose repeatability, even the big industrial robot manufacturers are working like that. You will see it clearly if you do some applications with calculated positions, machine vision etc. Thanks for the video!

I would use a cheap laser pointer and fix it on the end of the arm and run the code several times across all axis and check if the points match previous iterations. Maybe try different paths to test the same endpoints. That should test the precision nicely.
If the camera is on the head, you could lay a penny down and go thru the motions and return to see if the penny was in the same frame space for the amera to tell the accuracy.
yay i got a super early bird spot and was very excited to see that you had been in contact with them when your video notification came a few minutes later! could you please also check the real world payload, movement speeds and backlash in all axis at some point? what kind of things do you think you'll be doing with this arm? i would really like to see more about INNFOS' humanoid robots, and maybe replicating them, but maybe also combining this with jetson nano computer vision.
I can't wait to see your 7DoF arm with the timing belts and cables. You may actually achieve that 0.1mm precision :) Maybe not in the 3D printed version since the frame itself will flex, but the final version should be awesome.
I'm not sure if the precision test was conclusive. After pressure was applied, it returned to the original position. A better test would be to move it to a position, mark the exact point the head is at, then repeat the program and measure again. I suspect it's repeatable precision would be closer to the manufacturer's claim.
@@Skyentific Thank you very much for your reply. That's a shame, although the 2mm play at the end of the arm is a lot, anyway, locking forward to your next video. Keep up the good work :-)
Hello, This project got nuked, but do you still have the arm ? Nothing about this arm is complicated except the following. Which brushless motor are they using, what are the exact specs (how many coils/turn KV ratio ?) Are the arms supported by the motor bearings or supplemental bearings ? and what is the position sensor ? All the rest is relatively easy to copy, just needs the dimensional and the drive circuit is probably the same as any 3 axis gimbal so ...
For some reason there's a trend in enthusiast engineering spaces of miracle products getting promised and magically disappearing at the last minute without a trace. Oddest part is none of the videos claiming the products are the second coming ever get updated. In fact the people making them rarely admit there part in playing it up, or even acknowledge the scam as ever happening. Very suspicious.
I think your table just degraded that beautiful work of art. Solid table and using a dial indicator would be an accurate test. I think if you didn't have it sitting on a wobbly picnic table you would get the accuracy of what they claim.

Will you disassemble it a bit and see how it's made? I have a feeling the first rotation engine should be the most powerful, etc., but they all look the same size.
If it is 2mm along the x axis movement that involves only one motor, then the backlash in z axis that 3 motors are involved must be about 6mm ... is this correct?
The amount of polishing and iteration required to get something to work this well will probably come at a higher cost and time. But you will learn a lot :)
