William Robinson wrote to mention an entertaining Wired news article about vehicle meant for ****roaches. From the article: "Hertz has constructed a three-wheeled robotic vehicle that lets a Madagascan hissing ****roach navigate a room while perched atop a ping-pong ball. The ball works like a computer mouse's track ball. Where the roach moves on the ball, the vehicle moves in the room. Sensors on the bot can tell when it's going to hit something. It also has a semi-circle of LED lights facing the roach, so when it's about to hit an obstacle an LED will shine on the creature from the direction of the barrier, hopefully causing it to run in the other direction."
