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 micro 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 budget. Instead, you might want to consider some metal gear servos like these. Scroll down to the bottom for a cool animation! https://youtu.be/71RLPmq_848
