The minimum backlash of general planetary reducer is 25 arcmin。The repeated positioning error of AR2 should be 4.39mm。Why AR2 reache 0.75mm?

Hello. What a great job! But I always have a question. I found that the backlash of the normal planetary reducer with 50 reduction ratio is about 25arcmin, and the total length of ar2 and Ar3 is 620mm. As the second joint is used in this kind of reducer, it is found that the end positioning error should be about 4.39mm by calculation. Why do you make ar2 and Ar3 with an end positioning error of 0.75mm?

I would like to know that as well, I get the same value when doing the calculation.

  • I read the build manual for the AR3 robot and found that during the build for the control box there is nowhere in the BOM does it mention the 5v PSU used in the build. Any specific PSU you'd recommend or any 5v PSU will work?
  • Hey Chris, is there a minimum screen resolution for ARCS? it wont dynamically adjust to my screen size that is 1366x768.
  • Hi Chris, I've purchased all the parts to upgrade my AR2 to AR3 but have run into a issue right at the start. Your AR3 Robot Manuel shows additional mounting holes for the encoders on the back of the steppers. My steppers do not have additional mounting holes in the back. I'm assuming that I need to drill/tap these myself? I don't see anywhere in the instructions where it directs me to do this... I'm also confused on the length of the shaft out the back... mine all seem short. The instructions included with the encoder are pretty basic and do not really help to solve this issue. Thanks!
