Wow, that's a great robot.

I love the arm. What are you using to power the arms joints (which motors and what gear ratios)? Very simple gripper design too.

Great Job!

arm specs
 

thanks for the praise.

we used one fisher price motor per joint for the arm. they're running about a 1500:1 ratio from the pinion. the turret is operated with two globe motors. the ratio on the turret is 18:1.

any more questions please ask.
