The Arduino platform lends itself nicely to the world of robotics due to the ease of assembling the hardware and accessibility of the development environment, and this has been demonstrated very well by Jeremy Bohrer with his simple two-motor Arduino-based robot. With the addition of two bump sensors at the front, the robot can detect objects and then navigate around them. With a little more imagination and work on the sketch more diversionary options could be created, as well as controlling the speed and so on. Here's a quick video of the robot in action:
If you'd like to learn about Arduino - but not sure how to start - then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
