![]() This time, instead of a few LEDs, turned to an Android smartphone running an OpenCV-based app. Previously, we’ve seen turn a Hexbug spider into a line following robot with a pair of IR LEDs and a drop-in replacement motor driver. With a few extra parts, though, it can become a vastly more powerful robotics platform, as shows us with his experiments with a Hexbug and OpenCV. Any other suggestions or advice are welcome as well.The Hexbug Spider is a neat little robot toy available at just about any Target or Walmart for about $20. If not, can you recommend something else? I'd also like to get a couple of motors that would work well with whatever motor controller I need for the hex bug to prototype with, so motor suggestions would be helpful as well. The motors are low voltage (3.5V - 5V) so I'm looking for something that will be good for these motors. The hex bug uses an ST1155A dual motor controller on-board. The part I'm not sure about is the dc motor controller. I've settled on the HC-SR04 sonar sensor as it was recommended in a forum post, so I think I have that well in hand. I'd like to hack the hex bug into an obstacle avoiding autonomous robot (the light on my kids face when I told them we were going to "free" the robot was priceless!). After reading the docs, wiki, and forums, I think I can do this, but I would like a little guidance. I thought as an introduction a hex bug spider hack might not be too hard for me and it would really impress my kids as well. I love the idea of pythonic robotics and I just received my board a few days ago. ![]() I'm an electronics neophyte looking for an introduction with a fairly simple robotics project for me and my kids.
