The shoebox-sized robot exceeds [Bolt]’s top speed of 44-km/hour. At that speed, following a line gets tricky. It took the development team 8 prototypes to attain that capability.

The robot works in a simple manner, following a hand placed in front of the robot’s sensors. First, the robot checks for the presence of an object in front using the ultrasonic sensor.

The little robot, about half the size of a small egg, whirs along on invisible wheels, using a camera on its base to follow any line it's put on. When it meets a branching path, it picks one randomly.
