  1. Top 10Lego Robot Dos and Don’ts Teacher Professional Development Spring, 2002

  2. Do: Use books. Use the web. Use existing machines as inspiration. Use any resource and reference that you can find to construct and program your robot. Don’t: “Reinvent the robot.” Work in a vacuum. Number 10

  3. Do: Use sturdy and rigid connections. Use square frames. Use pegs to act as rivets in double-beams for additional strength. Number 9

  4. Don’t: Rely on robots that are held together by one Lego “pip”. Number 9

  5. Do: Use cross-bracing! Number 8

  6. Don’t: Rely on mere friction to hold the robot together. Number 8

  7. Do: Have good axle support. Number 7

  8. Don’t: Bend the axles. Put excessive forces on the motor axles. Number 7 This is a good way to snap the motor axle.

  9. Do: Use gears. Gears give the robot more strength and control. Number 6

  10. Don’t: Attach wheels directly to the motors. This makes the robot too fast and out of control. Number 6

  11. Do: Understand that the robot’s hardware and software work together. A change to one means a change to the other. Have your “hardware” guys and your “software“ guys know what each other are doing. Number 5

  12. Don’t: Work in isolation. Famous last words: “I didn’t change anything!” Number 5 ?

  13. Do: Use sensors! Sensors help deal with unknown conditions. Sensors relieve the tedium of programming using time alone. Number 4

  14. Don’t: “Gip” your students out of learning something about sensors and robotics. But, at the same time, don’t force them either. Number 4

  15. Do: Prototype early. Prototype often. Good way to sub-divide tasks without needing all of the Lego parts (e.g. the RCX). Number 3

  16. Don’t: Build the WHOLE thing first, program and all, and then try it. It is more difficult to make changes the more “final” the robot is. Number 3

  17. Do: Keep it simple! The more things that you add, the more that can break. TIE Number 1 Don’t: • But by the same token, don’t stifle creativity or innovation.

  18. Do: TEST TEST TEST! Build the game boards early and start using them NOW. When you’re finished testing, TEST SOME MORE! TIE Number 1 Don’t: • Wait until the night before the competition to finally try out the robot.
