Increase the challenge by adding a computer engineering and sensor implementation aspect to the robotics lab.

• (1) Line Tracking Kit
• (1) Ultrasonic Range Finder
• (1) Light Sensor
• (2) Optical Shaft Encoder
• (2) Potentiometer

This product replaces the plastic cap on the back of a 2-Wire Motor 269 with a quadrature encoder. Install this product and connect it to a 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 has traveled, and what direction it is moving.

• Increased feedback from your motors allows for more control.
• Programming Required! Consult your software provider for details.
• Communicates via I2C via included 4-wire Cable.
• Not compatible with the PIC Microcontroller.

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.

• Measure distances from 1.5in to 115in.
• Avoid obstacles.

With the Quadrature Encoder's two output channels you can measure both the position and direction of rotation of a VEX shaft.

• Calculate Shaft Speed.
• Calculate Distance Traveled.
• Increase Navigational Control.

The light sensor uses a photocell that allows your robot to detect and react to light.

• Analog input of light levels.
• Usable range of 0 to 6 feet.
• Find dark or bright areas.

The Bumper switch works as a trigger that provides feedback to the Microcontroller as events "happen".

• Rugged bumpers allows triggering by large impacts.
• Useful as a trigger in a variety of applications.
• Functionality is pre-programmed in the VEX Microcontroller.

These switches are great for signaling when a robot arm has reached the top or bottom of it's motion.

• Bendable sheet metal switch "arm" is very versatile
• Useful as a trigger in a variety of applications
• Functionality is pre-programmed in the VEX Microcontroller

With the Potentiometer you can determine both position and direction of rotation.

• Measure Angular Position.
• 250-Degrees of Adjustment.
• Adjustable mounting angle.

By measuring the acceleration of the robot, one can calculate the velocity of the robot, and more importantly the distance this robot has travelled.

• Three Axis Accelerometer.
• Selectable sensitivity via jumpers: ±1.5g, ±2g, ±4g, and ±6g.
• LED indicated power and proper connection.
