In this activity, a group of students each build an RCX robot. Each RCX is assigned a number. It will then have to tag the other RCXs with the number by using mail. 5 tags and the RCX takes on that RCX’s number. The winner is the RCX that has given its number to the most other RCXs at the end...

In this activity, design and construct an RCX car and program it to travel in a straight line until it hits a wall. Once it hits the wall, program the car to reverse direction and continue until it hits another wall at which point it stops.

In this activity, design and construct three RCX cars and program them to run a relay race. Each car is programmed to start the next car on its team by using the Mail function in ROBOLAB.
