Linkbot is a reconfigurable modular educational robot. Raspberry Pi is a low-cost single-board computer. Barobo Raspberry Pi is designed to run C-STEMbian, a free open source Linux operating system based on Raspbian for absolute beginners to use Raspberry Pi effectively. It provides a user-friendly solution for physical computing --- making and building in the physical world, and integrating sensors into Linkbot systems using Raspberry Pi.

In this project, a Linkbot and Raspberry Pi are used to build a police car, ambulance, or fire truck with a flashing light. The robot moves with a blinking RGB LED and siren of police car, ambulance, and fire truck. The entire system is controlled by a program including wiringPi with only 20 lines of code!
