Packet consists: step-by-step building instruction in pdf format; program in EV3-G language.
Equipment: 1 Lego Education EV3 Core Set (45544), competition field, safety fence.
In this work, we will use a Lego EV3 ultrasonic sensor to stop a racing car after the finish line. The ultrasonic sensor will act as an echo sounder. In technology, echolocation began to be actively used after naturalists and physicists described this phenomenon in wildlife. It turns out that many animals are used to identify obstacles in the search for food.
Mechanisms: overdrive gear.
