VEX IQ Sensor Overview

Sensor Name Sensor Image Sensor Specs & Use Default Functionality
Bumper Switch Allows for the sense of touch in the VEX IQ platform. Detect a wall, obstacle, or limit mechanism movement. With a Bumper Switch in port 2, it disables/enables a Smart Motor in port 4.
Touch LED Smart Sensor with red, green, blue LEDs. Constant on, off, or blink at any desired rate. Touch sensor with finger for interaction. Enables and disables Autopilot or similar robot running Driver Control Program when dome of sensor is tapped. Glows green when enabled, red when disabled.
Distance Sensor Uses ultrasonic sound waves to measure distance. Measures distance from 1 inch to 10 feet. Commonly used to avoid obstacles. Slows down and eventually stops as Autopilot or similar robot running Driver Control Program as the robot approaches an obstacle.
Color Sensor Detects the color of objects. Measures independent red, green, and blue in 256 levels each. Enables and disables Autopilot or similar robot running Driver Control Program when the sensor is “shown” a green card (enabled) or red card (disabled).
Gyro Sensor Measures turn rate and calculates direction. Frequently used in autonomous robot navigation and turning. With Autopilot or similar robot running Driver Control Program, it returns a robot to its original direction when driving stops.
Smart Motor Commands and measures speed, direction, time, revolutions and/or degrees of turn using its Encoder. No extra default functionality, but Encoders allow for superior motor control with simple programming.
