Edward Ros decided to modify an off-road remote control car with an Arduino and related circuitry as a foray into creating an autonomous vehicle. He added two ultrasonic distance sensors, some LEDs for directional lights, and modified the drivetrain to decrease speed and increase torque. Here is a short demonstration of the vehicle in action:
The code for Edward's vehicle is not terribly complex, and shows how simple it is to make a device with some level of intelligence. When building your own vehicles and Arduino projects with external circuitry, consider using one of our range of Arduino-compatible ProtoShields. They are a bright yellow colour which makes planning and referencing the prototyping areas easy on the eye:
