I'm Building a Robot

So far, I have been using a body opponent bag as my test subject for most of my experiments, but most opponents you will face in the ring or on the streets have arms.  In order to better account for this, I started to build mechanical arms to attach to the punching bag, but then decided to just build an entire robot instead.

Meet my new training partner:


I printed him on a 3D printer using ABS plastic using the inmoov designs for the parts.  I made a few modifications to ensure he can take a punch or two, but for the most part I stuck to the original designs for now.  If you want to get started building your own, Gael Langeven posted a great little starter kit with a single finger here.

For now, he only has a head, torso, and arms, and I mounted him to the body opponent bag for the sake of stability.  I don't plan to even think about legs for a while.  All of his motions are controlled by servos  of various sizes attached to an arduino mega board, but I still haven't finished calibrating any of them.

I will probably need to do a lot of calibration, wiring, and fine tuning before I can start teaching him to throw a punch, so it might take a while before I can actually train with him, but this is a good first step.  Until then, here are some more pictures:
