2 Wheeled Robot / Turtle
◀ Team OKAVO ▲ Electromechanics Kinematic Cube ▶

Over a few hours on a leisurely sunny Saturday afternoon I prototyped a 2 wheeled robot that I had been thinking about for some time.

It's hard to find information about this particular kind of 2 wheeled robot, most of the literature is about self-balancing robots where the center of gravity is above the axel.

Here we have the center of gravity below the axle.

It's kind of cute, a big hit with the kids.

Would love to get the opportunity to further enhance the hardware and software for smarter motion.
