Use motors to manipulate your environment.
Students can use the Ultrasonic Sensor to detect and and respond to an object.
Hardcoding the exact movements that a robot has to make isn’t very efficient. Therefore, robots have different guiding systems to help them navigate their environment. One simple yet effective option is to use colored lines on the floor, which a robot can follow using a sensor.
How would you know how to pick up a specific color object if you could not see? Work in a team of at least 2 people, blindfold one of the team members and place three different colored Lego brick in front of them on a table. Figure out the best way to get your human robot to pick of the bricks in this order: blue, yellow, red
