In grades IV and V, students learn about mechanical designing, critical thinking, team building, and problem solving. They receive an introduction to the parts used in mechanical designing of robots, such as DC motors, microcontrollers (the brain of the robot), various types of gears, axle locks, and caster wheels.
They begin by learning how to use screwdrivers and allen keys to tighten screws and nuts, and then they create different models, including a 4-wheel robotic car, 3-wheel car, soccer bot, push bot, simple crane, claw robot, rope cable car, and windmill.
