Battle Crab

A simple robot crab involving basic 3D printing, mechanics, Arduino programming, electronics and a bit of hacking.
I built this robot as a learning project. It is not as “polished” as it could be. I accomplished my goal, to learn the basics of servo controlled robotics, and kind of stopped. Improvement possibilities are abundant – feel free to adjust to fit your needs.
