Welcome back to our challenge class 4. Today we reviewed what we have learned from the first three classes. On the hardware side, we have tried large motor, color sensor, key pad and motor encoder. On the software side, we have learned loop and switch, variables, math modules. I have build robot that can read colors, go forward, backward, and self parking to the right. Today, we add a new capability to the robot, react to the touch. Once the robot touch the wall, it can stop, fire laser, back off, etc… Kids get creative about what they can do with the ev3. Next class, we will use color sensor again. We are going to build a traffic light detector. Red means stop, and Green means? Thank you everyone. See you next week.
