Lets make a Sandwich!

Robots are actually pretty dumb. When you give theminstructions, you have to be very specific and precise.

You have to specify things like distance and speed.

For example, you cant just say go forward. You have to say

Motor A travels at 75% speed for 3 seconds and Motor B travelsat 75% speed for 3 seconds.

Challenge Time

Let start with a few simple exercises.

1. Program a large motor to go forward at full speed for 3 rotationsand then break.

2. Program a large motor to go backwards at 75% speed for 3seconds and then coast.

3. Program a medium motor to go forward at full speed for 720degrees and then break.
