Activity 8: Drive in a Circle
For our eighth activity we will apply our knowledge of motors to create a new
behavior. While being able to move straight is important, we need to be able to
expand on that and make turns. This activity will have your TaskBot driving in circles
by varying motor power as the motors work in unison.
Parts Needed
• Fully assembled PRIZM TaskBot
• USB cable
• A charged TETRIX 12-Volt Rechargeable
NiMH Battery Pack
• Computer
