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, o, or blink
at any desired rate. Touch
sensor with nger 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.
