[John] wrote in to share his latest creation, an Arduino-controlled Bluetooth robot. You might remember him from one of his previous hacks, the Lawnbot 400. This time around, he has decided to scale things down a bit and focus his hacking on small R/C toys.
His Bluetooth bot was constructed using a cheap R/C tank he scored at a thrift store for about $1.50. He removed all of the bot’s parts, aside from the frame, the battery compartment, and the motors that drive the treads. He added in an Arduino, which he paired with an Ardumoto shield from SparkFun. The motor shield costs about $25, but he does have schematics available so that you can roll your own if you so desire.
A Bluetooth Mate was added to the car, which allows serial communication with any other Bluetooth device. Once everything was wired up, he paired the robot with his computer and got down to driving it by simply pressing keys on his keyboard.
It looks like a fun little toy to have around, and it seems fairly easy to construct. Check out the videos below of his robot in action, and be sure to check out his code/schematics if you are interested in building your own.
