About

This is the robot that Pybricks Tracker drives and records. The Robot Inventor hub sits flat on top under a beam frame that stiffens the body and gives it a handle. Two large wheels at the rear, on ports A and D, steer by turning at different speeds, a colour sensor on port F points down at the floor, and an ultrasonic sensor on port B rides low in the white front bumper at wall height. The distance it reads tells the robot how much corridor is left ahead: when a wall comes closer than the set threshold, it stops or turns on the spot. Every run can be tuned, mapped and replayed from Pybricks Tracker over Bluetooth.
