Packet consists: step-by-step building instruction in pdf format; EV3-G programs.

Equipment: 1 Lego Education EV3 Core Set (45544).

Optional equipment: second ultrasonic sensor, Lego EV3 Expansion Set.

A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself.

The swing also uses a lever at the base of the design. In this work, you will assemble a swing from a Lego EV3 set and program them using an ultrasonic sensor.

Task 1. Without sensors. Assemble the design of the robo-swing. Take off all the sensors and write a program for a swing without sensors.

Task 2. With one sensor. Mount one ultrasonic sensor to the man with a large motor on port A. Connect the ultrasonic sensor to port 1. Add counterweight to the second man to balance the weights.
