Silent Spring is an upscale version of version 2 of DDT; its name continues of the theme of insecticides (credit to Nate Franklin for the idea). The robot was designed to survive a number of competitions, being waterjet from a single block of UHMW and featuring indirect drive methods using urethane round belt. Despite its conservative design, the robot packs an enormous punch, sending itself and its opponent to opposite ends of the arena. No matter the opponent, parts will fly and robots will die!
