VEX Encoders

by

Introduction

Students will use the robots built in the Selecting Gears lesson and add encoders to the robots allowing the robot to input the number of revolutions of the motor to the software. The software will then be modified to autonomously controll the distance travelled.

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 axel or shaft is spinning. Using math calculations can be done to figure out how far a robot will travel for every rotation of an axel. This lesson will demonstrate how to install the encoder, how to do the math, and how to program the robot to use the information
