Project Name: Plank Battles
Controlled by: Programming or Remote Control
Programming Difficulty: Easy
Construction Difficulty: Medium
General Comment. Any battling robot gets the kids enthusiastic. This is no exception

Rules FOR STUDENTS

​You must use:
-1 NXT or EV brick
-up to 3 motors

You must:
Build a robot that can battle against another robot on a large plank. One robot starts at each end. The first one to fall off, loses. 
​

Tips For students

Tip: Cars with four wheels will go straighter. Especially if both motors turn one axel.
Tip: Cars that use gears will have better torque. A small gear on the motor and a big gear on the wheel will make the wheels turn slower, but stronger. To use gears, the wheel's axel can't go through the motor's hole.

TEACHER INFO

​When I have done this, I put the plank on three or four cube foot-stools. That way students could not construct a robot that 'gripped' the plank. 
​Grading option: The more battles won, the better the grade.
