This gearmotor is a miniature (0.94" x 0.39" x 0.47"), high-power brushed DC motor with 100:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft.
This is a programmable autonomous robot prebuilt kit that can be controlled via Gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. BeagleBone Black (Rev C) microcontroller provides the most flexible platform possible.
