Spool bot is a wheeled robot that is being used to evaluate sensor and computing platforms for future bipedal robot prototypes. It is capable of navigating complex indoor environments. It is made with empty filament spools, caster wheels from an old office chair, and some custom parts made on a 3D printer. It senses the environment using a depth camera and moves around using 2 standard servos. The brains are provided by an Arduino microcontroller and a laptop. The power for the robot comes solely from the laptop eliminating the need for external batteries.
