Three joint arm

[Lil' Lavery]

My personal design philosophy is single-joint or bust. Simpler to build, easier to control, easier to program, fewer points of failure, and require fewer motors (and speed controllers). There are plenty of other options to increase an arms "reach" other than adding more joints.

I do appreciate the desire and lessons that can be learned from taking this on as an off-season project, especially in regards to the control perspectives.

68's robot from 2011 had 3 joints (well 2 and 1/2; we had a shoulder, a elbow, and could flick our "wrist".)


Skip to 2:57 for the arm, sorry I couldn't find any better pictures. They're all at school.
