These photos are from a mechanical competition in November 2016. I built a tall wheeled robot from aluminum plate, steel rods, laser-cut wheels, gears, an AT89X51 controller, and ultrasonic sensors. The workbench photos show the mechanism and electronics coming together; the final photo shows the robot on the competition track.

Close view of the robot's large laser-cut wheels, gears, AT89X51 controller board, batteries, wiring, and ultrasonic sensor.
