Describe how many centimeters your robot travelled:

## EXPERIMENT 2

Mark a distance of 40 cm. Take time with a stopwatch, how fast does the robot travel this distance with medium speed. Guess how long it might take it to travel 20 cm. Experiment.

Describe how your robot performed when following the program:

## EXPERIMENT 3

Set the robot speed to maximum. What distance does the robot travel in 2 seconds? Set the speed to minimum. How long does the robot travel now in 2 seconds?
