Electronics

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

Measures accelerations on three axes simultaneously. By measuring the acceleration of the robot, one can calculate the velocity of the robot or the distance this robot has traveled. Accelerometers are also great for detecting collisions and determining if the robot is stopped or moving.

• Three Axis Accelerometer
• Selectable sensitivity via jumper: ±2g and ±6g
• LED indicated power and proper connection

This 12" battery extension cable allows for greater flexibility in robot design. Now you can design a battery compartment into your robot regardless of where the microcontroller is mounted.

• Designed for either of the VEX 7.2V Robot Batteries
• Mounting plate makes a permanent battery fixture easy

Ruggedized bumpers allow the switch to be triggered by large impacts without sustaining damage, such as when a robot bumps into a wall.

• Provide feedback to microcontroller as events "happen"
• Rugged bumpers allow switch to be triggered without damage
• Useful as a trigger in a variety of applications
• Functionality is pre-programmed in the VEX Microcontroller

Use these extension cables to extend the length of your motor, sensors, and other electronics wires.

It might be hard to drive your robot without a controller. The VEXnet Joystick allows a human operator to control their robot in real time. Similar to many video game controllers, the VEXnet Joystick features 8 face buttons, as well as 4 "trigger" buttons.

Compatible with the VEX ARM® Cortex®-based Microcontroller Digital Outputs. Use these for feedback indicators, to debug code, or for cool light patterns.

• (3) Red LED Indicators
• (3) Green LED Indicators
• (2) Yellow LED Indicators

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

These switches are great for signaling when a robot arm has reached the top or bottom of its 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 ARM® Cortex®-based Microcontroller

Reads the difference between a black line and a white surface; can be used with programming software to follow a marked path on the ground.

• Navigate down a marked path
• Use for light sensing
• More autonomous function

The Motor Controller 29 goes between a 3-wire Motor Port on a VEX Microcontroller and a VEX 2-Wire Motor. It uses a standard PWM signal to provide motor control.

VEX EDR 393 motors are the primary motors used for robot mechanisms. We also offer replacement gears to give your motors a speed boost. Use 393's to power your intakes, lifts, and drivetrains.

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

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

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

Use the VEX Power Expander to add a secondary power source for four of the PWM outputs on the VEX ARM® Cortex®-based Microcontroller.

• Attach a 2nd battery to your robot
• Power up to four (4) Motors or Servos
• Reduce motor load on primary battery
• Run your robot for longer!

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
• Detect obstacles using high frequency sound waves

The VEX ARM® Cortex®-based Microcontroller coordinates the flow of information and power on the robot. All other electronic system components must interface to the Microcontroller.

• STMicroelectronics ARM® Cortex® M3 user processor
• (8) Standard 3-wire Motor ports
• (2) 2-wire Motor ports
• More than 20 sensor inputs and outputs
• Programmable with easyC v4 or ROBOTC for VEX Robotics v4.x

The VEXnet Backup Battery allows you to mount and connect (1) 9V battery. This battery keep VEXnet alive when the main battery fails.

• Works with the VEXnet Upgrade
• Works with the VEX Cortex Microcontroller.
• Works with the VEX ARM9 Microcontroller.

Extend your runtime by powering your VEXnet Joystick directly from a wall outlet. Simply connect this adapter to the VEXnet Joystick's programming port and you're good to go for hours and hours.

The VEXnet Key 2.0 provides wireless communication between VEX ARM® Cortex®-based Microcontroller and VEXnet Joysticks. This key utilizes the new VEXnet 2.0 communication protocol over a custom 2.4 GHz data radio.

• Works with the VEX ARM® Cortex®-based Microcontroller
• Uses VEXnet 2.0 communication protocol over 2.4 GHz data radio
• Rubber fins help retain key once installed
