Here is my latest robot. Al.I.S.E is an Aluminum, Infrared Scanning Entity; or just an old-school style crank arm hexapod :) This project was based on the mechanicals of the "Hexapod Monster" kit I built and reviewed back in 2008. I scaled it up a little, and added 2 super torquey gear head DC motors I found at a surplus store in Minneapolis. Power comes from a 9.6v RC transmitter pack, along with a separate 9v for the BS2 microcontroller. Motor control is handled by a Solarbotics 1198 CMD driver board kit. I used pencil top erasers for her feet, and found that using scrap pieces of solid core cat5e cable came in really handy for sub-board inter-connects. Obstacle avoidance is fairly rudimentary at this point, as I am only using 1 IR sensor along with flanking IR LED's. It still seems to work fairly well though. I definitely need to tweak the coding some more. Check out the movie I made of her backing away from some library books and making a run for the front door!
