crumblebot round two

Like the other set of Crumble missions these start easy and get tougher.

remember

• Push yourself to extend what the robot does before going on to the next mission.

• For example: mission 2: can you make the robot spin clockwise then anticlockwise?

• There are quite a few exercises that involve counting things or doing something a certain number of times so these should be easy to extend.

Notes:

• Mission 10: This is a game to test your response time. Press the button and wait, after a random delay between 1 and 3 seconds the lights will quickly start turning on starting with the rightmost one and going to the left with a delay of 1/10th of a second between them. You have to press the button again as soon as you see the lights. When you press the button the lights freeze, telling you how many 1/10th of a second it took you. The robot has a buzzer, you could try this blindfolded and use the buzzer to mark the start. Just a thought.

• Mission 11: I haven’t had a chance to explore this much but I bet there’s loads of fun things you can do here.

  • Get the robot to count the lines by lighting up its LEDs.
  • Program the robot to stop on the 3rd line (say).
  • Can you find a way to measure the thickness of the black line?
  • Can the thickness of the line be used to find the speed of the robot?
