How to Make a "Hungry" Robot Sometimes the best robots are more emotional and less functional. Gadget Freak Eunchan Park shows you how to build a coin-eating robot using Arduino, a 3D printer, and a ...

If you want an easy project to complete in a day or so, or something to introduce kids to the world of robots and electronics, make this light-following robot your weekend project.

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.

Learning to build a robot arm will teach you how to breadboard a circuit, how to program your Arduino, and how to work with moving parts.

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.
