Kitbots

Kitbots is the home of the Saifu antweight combat robot kit — one of the most respected antweight combat robot kits in the sport. Founded by Peter Smith of Team Rolling Thunder, a veteran builder and Servo Magazine contributor with 20+ robots to his name, Kitbots designs bots that reflect years of hard-won arena experience. The Saifu isn't just a kit — it's a proven competitive platform that builders know by name.

The Saifu pioneered the hubmotor beater bar concept in the antweight class, combining a compact all-in-one drivetrain with a devastating drum weapon in a package that is both elegant and brutally effective. Now in its third generation, the Saifu V3 reflects years of refinement across dozens of competitive events — including multiple Motorama appearances. This is a kit for builders who already know the basics and are ready to compete seriously.

At ItGresa Robotics, we carry the full Saifu lineup including the Complete Kit, spares, and the wire harness — everything you need to build, compete, and repair.
