Designed by a Combat Robotics Veteran! The Saifu Antweight Chassis & Drum Kit was designed by veteran builder Peter Smith of Team Rolling Thunder, creator of over 20 combat robots. Saifu represents years of evolution and battle-tested experience in the antweight class. Durable, Lightweight, and Built to Hit Hard This version of Saifu features a tough UHMW chassis with integrated wheel guards and carbon fiber top and bottom plates. The frame is designed to absorb abuse while keeping your components protected round after round. Powerful Hubmotor Weapon System The Saifu’s beater bar weapon is a precision-machined aluminum hubmotor—one of the first commercially available in combat robotics. It uses replaceable hardened steel bolt teeth for long life and easy maintenance. Because it’s a direct-drive design, there are no belts or pulleys to break under impact. Battle-Tested. Builder-Approved. Saifu has competed in over 18 events, including Motorama. It’s a proven, powerful, and customizable platform for antweight robot builders who want a serious edge in the arena.
