In this activity, the students first choose an animal that they want to create and think about the types of motion that the animal does. Then, they approximte the animal's motion using gears and motors. This is a good way to use gears and motors in a situation other than a car. At the end, present y...

Does anybody have plans for a seismograph?

In this activity, design and construct an RCX sturdy car and program it to be controlled by touch sensors that can push “dirt”
See "Bulldozer-RCX" PDF for detailed instructions.

In this activity, design and construct an RCX car that can bridge a one
foot gap without falling.

In this activity, design and construct an RCX or NXT car and program it to enter
a tunnel, then reverse back out when it encounters a darker light reading.
See the Activity PDF's for detailed instructions.

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, set up an RCX “voting booth” to gather data using touch sensors. The presses will be recorded and plotted into a graph.

In this activity, design and construct an RCX tractor that is capable of pulling a heavy load across a floor. (NOTE: Gears will be needed.)
