A Tale of Three HAMs (3HAM) is a continuation of the HAM line of robots. In short, a long line of wacky, fun, and unpredictable collaborative entries that stray from the meta.
See the video below for a sample of the hilarity that is 3HAM!
3HAM uses bristle locomotion to move. Vibrations in the weapons (intentionally unbalanced) induce bouncing in the chassis. Landing on compliant bristles will cause the robot to inch in a direction depending on how they are biased. Go HAM in particular used 3D printed TPU bristles which could be biased using a a servo for forward and reverse direction.

Brief summary on HAM: Each part is designed independently and virtually in a vacuum; we agree only on the attachment features and how the robot will generally operate. To make things even harder (more fun), both builders partake in the control of the robot but in an non-intuitive manner; some teams split drivetrain and weapon function in to two different operators but on HAM robots each operator is responsible for all functions!
