I filed it under “H” for “Toy”….
MAKE Flickr pool member wirehead writes “I’m bringing up the gen2 circuit board. This should be the sort of thing that a qualified electrical engineer would whip out in a matter of minutes. But, I’m a programmer who likes to mess around with technology, so things sometimes take a little longer than they ought to. Or I connect power to ground and ground to power. I do that sometimes, too. But now, I can program this board to do stuff, once I get the LEDs all soldered up. Soon, you will start seeing this board in my light art”… Link.
Battle Kits are designed along the lines of the most successful combat robot ever: BioHazard. We started with some of the key features in BioHazard and developed four rugged, low-profile, high-performance, mobile platforms on which you can build the next killer robot! Thanks Doug! 
Grower is a small ‘rover’ vehicle which navigates around the periphery of a room. It hugs the room’s walls and responds to the carbon dioxide levels in the air by actually drawing varying heights of ‘grass’ on the walls in green ink. The Grower robot senses the carbon dioxide (CO2) level in the air via a small digital CO2 sensor. This sensor is mounted high on a wall of the exhibition space and sends data wirelessly to the robot. The number of people in an exhibit space breathing in oxygen and exhaling CO2 has an immediate effect on the sensor. My robot takes a reading of the CO2 level every few seconds and in response it draws a vertical line in green ink on the wall. Thanks Doug! 
Hektor consists of a suitcase which contains two electric motors, a spray-can holder, toothed belts, cables, a strong battery and a circuit board which is connected to a laptop and controls the machine. The motors that are mounted onto the wall suspend the can holder through the toothed belts and define its position by changing the length of these belts. Thanks Doug! 
The Scribbler is a fully programmable, intelligent robot with multiple sensor systems that let it interact with people and objects. It navigates on its own as it explores its surroundings, and then reports back about what it senses using light and sound. With your personal computer and choice of free software, write your own programs for your Scribbler Robot. [
TerminatorBot is a crawling robot with two arms that can also manipulate objects. It’s perfect for crawling around the wreckage of a disaster site but the limbs collapse into a cylindrical body that can be tossed or launched into specific locations, making the machine attractive for space applications or military use. 
The scribbler bot is essentially a drawing machine that converts digital information into a physical drawing. The bot is made up of a software component and a hardware component. The software component analyzes a picture taken by a web camera (or just about any other image source), creates a unique line drawing from that analysis, and exports a point list that corresponds to the points that make up the lines.
