Followbot
As my final project for a course called principles of engineering, I was part of a team of five that created a walking robot that followed someone. I was a member of the mechanical subteam, which designed the walking mechanism as well as the chassis organization. Our walking mechanism involved six legs, which avoided the complex controls problem of quadrupedal movement. These legs were driven by four servo motors, with the front and back legs on each sides being driven by a four bar linkage, moving the robot forwards, and the middle leg rotating each side of the robot up and down, so as to allow forward motion of the other legs. The balancing of the weight of the robot was also difficult, and not entirely successful, as we had to balance motors, controls, and a battery on a chassis whose balance points were moving, while waiting on software integration for testing.
