Bassbot was originally designed to be a simply device which can deliver a heavy beat on demand. Through the course of the year, the project evolved into something much more, where the aesthetics were just as important as the function. While the outside of the robot was made to look like a severed robot leg hijacked by evil scientists to do their musical bidding, the inside functions similarly to a human foot.

A pneumatic piston is used to actuate the ankle joint which pushed the foot down into the bass drum pedal. The piston is controlled by a solenoid and a simple circuit board which are located inside the leg. Four wires (power, ground, and two signal wires), as well as a pneumatic pressure line, sprout from the stump of the leg along with several other decorative wires and tubes. The foot is capable of playing more than 4 beats a second. Another important feature is the adaptability of Bassbot. The bolts in the heel of Bassbot allow for it to attach to the back of most foot pedals, allowing the design to expand to playing a hi-hat, or for use on piano pedals.
