Learning Goal: Understand how to write a program to control a robot.

Lesson 6 - Touch sensor

Add a touch sensor to the front of your robot.

A simple way to do this is to attach the touch sensor to a beam, and attach the beam to the brick body.
Use at least two pegs to keep it stable. Make the touch sensor stick out in front of the robot.

..........................................

Watch this video lesson:

Part 1. Program your robot to move forward until the touch sensor is pressed, then stop.
Expand your program so that the robot is able to autonomously

• move forward until it hits an obstacle with its touch sensor
• then backs up
• then turns and goes forward again.
• Use a loop in the programming so that the robot performs these steps forever
  as it explores a new environment.
  Make sure it is annotated. Save it as Touch1Yourname.
