Robot Arm GBC

Here's my latest Great Ball Contraption module. It features a robotic arm with five degrees of freedom using two networked NXTs. It's an incredible overkill for moving LEGO balls from one spot to the other - but that's whole point of GBCs, isn't it!

 

Thanks to Akiyuki for inspiration and the wrist design.

 

You can see this module in person at some upcoming LEGO fan festivals - BrickFair NE in Manchester, NH in early May, or at BrickFair VA in Chantilly VA in early August. www.brickfair.com
