Re: Wanted: CIM RPM data For actual robots

2 Cims per side ? Full ~130lb robot or just a chassis ?

Just out of interest, how controllable was the robot at 19 fps ?
Yes, 2 CIMS per side. Full 120 Lb robot.

The robot was decently controllable at that speed but to get there we needed to run through the gears as it's accelleration was poor in 3rd gear. Fortunately our gearboxes were shift-on-the-fly.
