Started: June 2019 Completed: August 2019 Released: September 2019 Instructions are available here I made a car that carries the balls with Adaptive Cruise Control (ACC). I use Lego’s Powered Up platform. This car has a Powered Up hub, driving motor, and distance sensor. I programmed to run while keeping a certain distance from the obstacle.   The car body was made with a focus on compactness. A small body is packed with a Powered Up hub, motor, and distance sensor. This car is small but four-wheel drive.   The loading part was made using a Powered Up move hub. Two motors built in the move hub drive the star wheel and gate. A distance sensor is used to detect the arrival of a car. With the red lever, we can press the green power button on the Move Hub. I used a new part 35446(BrickLink) for the star wheel.
