This investigation is very much related to the ch.2 Gears. It's because the speed of the robot was propotional to the teeth of the Gears. As most of you guys know, the more the teeth, the faster speed the robot have.
Firstly you should set the robot to for forward for 3 seconds.Then you measured the distance that robot travelled. This process is repeated three times for the accurate value. divide average value of the robot travelled by time in order to get the instantaneous speed of the robot. This process will be runned for all conditions, which is used to make hypotheses. then you might predict the value and compare to the actual value. in my case, we've got 49.3cm/s, and our hypothesis was 50.3cm/s.

Did you use the first hypothesis or the second one ?
Your explaination about measuring the distance that a robot travelled is somewhat confusing.
could u tell me about ceramics gear?
