Robot arm design, my ideas and progress so far.

Armpic2.jpg

Building an arm for your robot can be the hardest part of robot design. There can be many different designs besides a humanoid design. For example you might have a CNC style XYZ axis or even a tentacle design where multiple joints are surrounded by cables. For BoozeBot I've decided to go for a humanoid design because I would like him to be able to pick things up like a person would. Reguardless of your design the first problem you are likely to face is strength vs weight.
