Living proof is this human-following robot/car that was build by the YouTuber over at DIY Builder, which relies on an Arduino Uno as the brain of the device. The video that you can find embedded ...

The build relies on the classic Arduino Uno microcontroller, which talks to a HC-SR04 ultrasonic sensor module and two infrared sensors in order to track a human target and follow it around.

Creating your own human-following robot using a Kinect and Raspberry Pi involves several steps, but the detailed instructions provided by Team Turtle Rover make the process manageable.

The Arduino micro controller can be easily removed from the robot, and it is placed on the prototyping board so that you can program to your heart's content. It easily connects to a PC or laptop ...
