Grip-E

UPDATE: Depending on the servos you choose, they might overpower the nerdduino. BigLazyB used a 470uF capacitor across the nerduino's Vcc/Gnd to fix this issue.

Give your Chip-E what every biped deserves, a set of fully functional arms! This awesome upgrade greatly increases Chip-E's physical capabilities. With these two sexy arms, Chip-E can now do perfect push-ups, hardcore hammer curls, pick himself up off the ground, and much more!

Materials needed:
6x 9g 180° servos
4x M2x10 hex screws
4x M2 hex nuts
4x M3x15 male standoffs

The Chip-E hardware kit includes a bunch of spare parts, which includes extra M2x10 hex screws, M2 hex nuts, and M3x15 male standoffs.

A tip on the servos: I used these TowerPro servos in my Chip-E because they were so cheap, but I've had a lot of problems with them and a few broke quite easily, so I wouldn't recommend them unless you are on an extremely tight buget. Instead you might want to consider some metal gear servos like these.
