A maker called heychaostheory built a functional, autonomous Star Wars mouse droid with a dedicated party mode button, and published the full build on Instructables.
The hardware stack is specific and replicable: an off-the-shelf metal robot chassis carries two gearmotors, an Arduino Uno handles logic, an L298 motor driver controls the drivetrain, and ultrasonic sensors manage obstacle avoidance. The 3D printed body mounts via heat-set inserts and nylon standoffs. Party mode is not a gimmick. It is a physical button wired to a DFPlayer Mini audio module that plays music, paired with onboard LEDs for effect.
What makes the full build worth reading is the integration detail, specifically how the commercial chassis, custom printed shell, and consumer modules combine into a coherent, scalable robot at accessible cost. This is a blueprint, not a one-off.
