Most of the robot arms we see are interesting but small much more than toys. Usually, they use RC servos to do movement and that’s excellent for generating some standard movement, but if you want a thing a lot more industrial and capable, check out out [Pavel’s] RR1 — Actual Robotic A single. The beefy arm has six degrees of freedom run by stepper motors and personalized planetary gearboxes. Each individual joint has an encoder for precise placement comments. The initially prototype is currently operating, as you can see in the online video underneath. Variation two is forthcoming.
When you see the detail in motion, you can instantly explain to it is not a toy. There are four NEMA23 steppers and 3 lesser NEMA17 motors. When there are 3D printed elements, you can see a good deal of metallic in the establish, also. You can see a video clip of the arm lifting up a 1 kilogram barbell and finding up a refreshing delicate consume.
From [Pavel’s] reviews about the second revision, it sounds like he is making an attempt to decrease backlash which need to be a bit of a trouble with the to start with version. One particular point we did not see had been any layout data files for any section of the device so, for now, it will just have to serve as inspiration. But due to the fact the task is up on Hackaday.io, we are hopeful we will at some point get a peek at the 2nd revision structure.
Meanwhile, if you want to create one thing more modest, possibly raid a CD generate. Although servo-centered arms have a poor popularity, you can, in simple fact, make them pretty capable with some perform.
