The block held 300 pounds, reaching its presecribed/predicted force limit. This is proportional to 240,000lb if the block would be made out of steel to its intended dimensions, a hexagon of 4 foot radius.  




**CS102:**

CADing a Beastly Robotic Arm

Note that the gears mesh and were designed by hand (not by Autodesk's gear generation function!).

**Robot Arm Rumble**

This is awesome robot arm design that I never had a chance to build but designed for CS102.
