Attach, program, and demonstrate to the class how to use rotational sensors to accurately move a robot from point to point.

Prepare a presentation showing students how to accurately calculate the values for the rotational sensors attached to their robots.

Select activities for students to test using rotational sensors.

 

Students will:

Participate in a teacher led discussion on what a rotational sensor measures and how rotational sensors can be used in conjunction with wait-for statements, program control loops, and rotational sensor conditional statements to control autonomous robots.

Participate in a teacher led discussion on the use of rotational sensors to measure the speed of rotating axles using compound gear trains.
