This Arduino-UNO powered Wanderer robot uses an Arduino Motor Shield, a Parallax Ping))) sensor mounted on a small, forward-mounted scratch-built pan & tilt and a small TV video camera / transmitter mounted on a larger, rear mounted, CrustCrawler pan & tilt. The Chassis is a 2WD platformâ€”it and the controller boards were kindly provided by the Maker SHED at Oâ€™Reilly Media for a story we published in the July-August issue of Robot (check out the Maker Shed–a lot of cool robotics stuff there).
Anyway, Steve Norris and I loosely discussed a wandering robot with a video feed before it was fully assembled and programmedâ€”I built the small pan & tilt out of two servos, two model airplane clevises and other nick-nacksâ€”a fun project in itself, and did a partial assembly of the deck and Crustcrawler pan & tilt, but Steve created the final design of the platform and wiring, completed the build and programmed the project. The wanderer avoids obstacles and cliffs while sending streaming video to a TV. It looks about scanning the environment when it finds an obstacle or cliff. See it run here.
Steve is a prolific builder of robots and has created dozens. He has contributed to MAKE magazine and has been featured on their blog a bunch of times. He has made such an impression that he is scheduled to appear on the new Mad Scientists special being produced by the National Geographic TV channel and which is scheduled to be broadcast in early October.
