1. NXTG Workshop Day 2 Programming with Touch Sensor Light Sensor Ultrasonic Sensor Repeat CJ Chung Associate Professor of Computer Science Lawrence Technological University

2. Start-Touch Wait until the touch sensor is pressed; Then start the robot to go forward Stop after a second

3. Start-Light Locate the robot in the middle of the ring Wait until the light sensor detects very bright (lantern) light Then start the robot to go forward Stop after a second

4. Start-Light

5. Stop-Touch Go straight until the bumper is hit then stop

6. Stop-Edge Go straight until the white edge of the ring Then stop

7. Ultrasonic Sensor Test

8. Loop To repeat a sequence of code Until Elapsed time Number of repetitions Sensor condition is met Logic becomes true Forever

9. Say Yes – 10 times

10. Make the robot move around in the ring – Basic Sumo (Sumo0) Repeat the following forever: Go forward until the edge Backward slightly Spin right

11. Sumo0

12. First Sumo Competition Some matches Ask students to list ideas to improve the Sumo robot

13. Repeat Until Spin a little bit until it detects an object less than 10 inches If detected, stop spinning and say Object

14. Mission: Find a static object using the ultrasonic sensor & push it out of the ring, box Robot but the robot should remain on the ring!!
