Part of Lesson Plan: VEX Encoders

Activity Overview / Details

Optical encoders use infrared beams of light and a notched wheel to record on and off states.  This can be used to detect how fast an axle or shaft is spinning.  Using math, calculations can be done to figure out how far a robot will travel for every rotation of an axle.  This lesson introduces encoders and shows how to install them.  Attached is a short Powerpoint, the VEX pdf, and pictures of the encoder.  

Students will take notes on the P-point and also be notified that the pdf is located in the VEX user guide binder.   This will be followed by an example of what math needs to be done before programming.

Attached is a picture of the installed encoder, a pdf of the instruction manual. I need to create a power point of the mathematics and then a lesson on how to program the autonomous code.
