How can you design robos in robowar?

I have had pretty good luck with buying small remote control cars at the dollar store and taking them apart to reconfigure them into what I want, but that ends up with wires connecting the robot to the controller. Some of the people I work with have pieced together radio control cars and other parts to get radio control robots. If you prefer robot kits, some hobby stores sell a few inexpensive ones that are sometimes configurable. Otherwise some of the less expensive construction kits like LEGO or K-NEX or Construx or a few others have motors and gears in the kits. If you have a larger budget, Lego Mindstorms or Bioloid are more advanced kits that are programmable and autonomous. Some very important terms to keep in mind are: remote control - usually connects the robot to the controller by a wire, you can usually keep the batteries in the controller to make the robot lighter. radio control - the controller is a transmitter, the robot has a receiver on it, both need batteries. autonomous - you set up the robot and program it to run sets of commands, when you set it down and turn it on it runs the commands. Highest skill level, usually requires programming knowledge (like BASIC, C language, Assembly, ForTran, COBOL or some others) and electronics knowledge (like power supply vs. load, Programmable Logic Arrays, Trans/ceivers, sensors, and many other options). But of course it is the most fun. operator controlled - the robot has motors in it, maybe some electronics, it doesn't move until you push a button or lever on the controller. sensory feedback - the robot can have switches, sensors or detectors on it that send information back to the controller (or its processor if it is autonomous). Might require a transmitter on the robot and a receiver in the controller (with some indicators to tell you what the robot is "sensing"). There is a ton of things that can go together to make a robot, if you learn how to fix appliances and cars it definitely helps you figure out robots.
