Giving the Hexbug Spider freedom to explore on its own

hexbug-hack

[Eric Gregori] recently spent some time messing around with a Hexbug Spider, and wrote in to share some modifications he made to the toy. In its unaltered form the robot can be controlled remotely, and while it’s fun to play with, the excitement is short lived. Using a TI MSP430 along with a small motor controller kit he put together, he gave the Hexbug a bit more personality.

The kit is really just a simple board used for mounting the MSP430 and FAN8200 motor driver, along with an IR emitter/sensor pair. It would be easy enough to put something similar together yourself, though if you are looking for a protoboard/deadbug/PCB etching-free solution, his Spider Hack kit is a quick and easy solution.

[Eric’s] walkthrough shows how to disassemble the Hexbug, and details which components need alterations before the controller board can be properly mounted. A few soldered wires later, the toy is ready to be reprogrammed, a process [Eric] carries out using the Launchpad board from which he lifted the MSP430.

As you can see in the videos below, calling the robot autonomous might be a bit of a stretch (I don’t see it walking to the kitchen to make me a sandwich), but it can navigate and avoid objects with ease.
