Plexiglass shatters with splinters when hit or bent sharply and the edges are sharp. Lexan and other polycarbonates can take the shock much better and are more appropriate for use on our robots. Many teams also used perf stock (aluminum) as it is easy to mount components using ty-wraps or simple hardware. It is easy to pop-rivet to frames and can be cut with hand held metal shears.
