Project Name: Catapult into Bin
Controlled by: Programming 
Programming Difficulty: Medium
Construction Difficulty: Medium
General Comment. This is harder than it looks

Rules FOR STUDENTS

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

You must:
Build a robot that can go travel 4 metres, then shoot a ball into a bin. 

Tips For students

Tip: Generally the motors aren't powerful enough to flick a ball without using gears and/or some sort of rubber band. It's good to stretch a rubber band to hold the arm that holds the ball; then use a motor to release the rubber band and ball shooting arm.
