Carefully applied skin grafts after a serious burn or injury can mean the difference between life and death. Likewise if you ve watched a robot combat match you know that a robot is doomed if its skin is ripped off by an opponent. The same follows for the failure of fasteners for a wheel assembly a weapon or a strategic internal system. If any of these are torn off in the arena that robot is most likely going to lose the match. The information in this chapter will help you make your own decisions about what materials and construction techniques you will use after thoughtful consideration of the many types of elements and fasteners available. Each material has a best application. Before you begin building you should look up specifications in suppliers catalogs and use logical design practices in the layout and construction of your combat robot. Use common sense. Talk with friends who have done mechanical design. Look at successful designs and determine just what made the design work so well or what caused others to fail. Don t be afraid to ask others for advice. Get on the Internet and converse with those who have built a robot similar to what you have in mind. Metals and Materials When you think of durability you probably think of metals first. However some of the newer plastics offer many advantages over metals when it comes to building robots for competition. High-Strength Plastics With virtually unmatched impact resistance outstanding dimensional stability and crystal clarity Lexan polycarbonate resin continues to be one of the popular types of materials for use in combat robots. The product is a unique thermoplastic that combines high levels of mechanical optical electrical and thermal properties. GE Structured Products is one of the leading suppliers of Lexan sheet .
