Main Idea
Students learn about robotic sensors. They understand that robot sensors are based on the functions of human sensory organs. They study how the sensors (touch and colour sensors) work by creating their own robots and programming them. They identify when and why we use robotic sensors in real life situations.

Description
Discussion: Part A) Students talk about human senses and their functions (Sense of sight, sense of touch, sense of smell, sense of taste, and sense of hearing). They should be encouraged to discuss how we can link our senses to robot senses (References to Lego Mindstorms Ev3 sensors should be made). (15 minutes)
Part B): Where are sensors like these used in everyday life? (gyro, colour, ultrasonic, and touch sensor)-lights, automatic doors, parking sensors etc. (10 minutes)

Worksheets-Activities: Teacher has to demonstrate how the touch and the colour sensors work. (10 minutes). Students should work in groups and build a car and add a touch and a colour sensor in their robots (1 hour). They should program their robots to stop by using these sensors. (20 minutes).
Discussion: Part A) Students present in groups their robots in class and a discussion takes place. They ask questions and they find solutions to every difficult part of their activities. (30 minutes)
Part B) Students are motivated to think situations of real life that robots should “replace” humans. Afterwards, they have to identify which robotic sensors are used in these situations. (space exploration, entering dangerous areas, mowing lawns etc.) (15 minutes)
Worksheets

1.Create a car by using Lego Mindstorms Ev3.Add a touch sensor and a color sensor in your robot.
2.Program your car to move until it hits an obstacle. When it hits the obstacle, the car has to stop.
3. Program your car to move until it detects a black line. When it detects the black line, the car has to stop.
