The Hexbug Spider is a neat little robot toy available at just about any Target or Walmart for about $20. With a few extra parts, though, it can become a vastly more powerful robotics platform, as [eric] shows us with his experiments with a Hexbug and OpenCV.
Previously, we’ve seen [eric] turn a Hexbug spider into a line following robot with a pair of IR LEDs and a drop-in replacement motor driver. This time, instead of a few LEDs, [eric] turned to an Android smartphone running an OpenCV-based app.
The smartphone app detects a user-selectable hue – in this case a little Android toy robot – and sends commands to the MSP430-powered motor control board over the headphone jack to move the legs. It’s a neat build, and surprisingly nimble for a $20 plastic hexapod robot.
You can see the OpenCV-controlled Hexbug in action after the break, along with a video build log with [eric] showing everyone how to tear apart one of these robot toys.
