Over the summer of 2011, I welded and wired together a rideable hexapod based on designs by Rick Pantaleo. It's built with a steel tubing frame (MIG welded), controlled by two drill trigger controllers, a found racing car seat, and powered by donated A123 lead acid replacement batteries with reused tennis balls for feet. I took it to two New York Maker Faires and let kids ride in it.
What I did: This was my own project, focused on fabrication of existing plans, with modifications to the wiring.

Inspired by videos of dancing hexapod competitions, I built an 18-servo hexapod and programmed it by myself. It was made of ABS plastic, 18 servos, an Arduino nano, and a Pololu serial servo controller. With Prof. Dan Frey's permission, I substited this independent project for the normal coursework for Design and Manufacturing I. The hexapod used the tripod gait to walk and turn around.
What I did: This project was my own design, fabrication, and programming.

I wrote an Instructables about it which was featured and received over 44,000 views: Simple 18dof Hexapod, Arduino nano (optionally with pololu maestro).
The code may be found on Github.
