The VEX Accelerometer measures accelerations on three axis simultaneously. By measuring the acceleration of the robot, one can calculate the velocity of the robot, and more importantly the distance this robot has travelled. Accelerometers are also great for detecting collisions and determining if...

This product replaces the plastic cap on the back of a VEX 2-Wire Motor 393 with a quadrature encoder. Install this product and connect it to your Cortex Microcontroller via I2C to receive direct feedback from the motor. This encoder provides information on how fast the motor is going, how far it...

Use the VEX LCD Display to receive real-time feedback from your robot to perform live debugging. View multiple stored program configurations and select between them or provide additional user-input to robot. Note: Requires VEX programming software sold separately. You will need the Serial...

Avoid obstacles and measure distances with the ultrasonic range finder. Device emits a high-frequency sound wave that alerts the robot to things in its path. A Programming Kit is needed to change the program in the VEX Controller. Measure distances from 1.5in to 115in. Avoid obstacles. Create more...

The light sensor uses a photocell that allows your robot to detect and react to light. With the light sensor, you can program a whole new range of capabilities to your robot. A Programming Kit is needed to change the program in the VEX Controller. Analog input of light levels. Usable range of 0 to...

Kit includes a pair of simple limit switch sensors custom built for the VEX Robotics Design System. Switches send a signal to the Microcontroller when that are triggered. These switches are great for signaling when a robot arm has reached the top or bottom of it's motion. Provide feedback to...
