Description

PDF

This is an open-source Plastic Antweight combat robot, intended for the SCAR component kits available from Turnabot and Team Malice. This and other community designs can also be found on the Team Malice website.

It placed 4th overall at Society of Combat Attack Robotics (SCAR)'s May Plastics Pandemonium (4 May 2024) as well as at Nexus Knockout! It placed 1st in Build Fight Fun! at InfinitiCon Tallahassee and in Robot Renegades Summer Showdown as Killer Parakeet by Helen Claudio of Firewolf Robotics! 

The design of this project is my own work, however it is heavily inspired by the full-combat Antweight “Night Force”, which in turn is inspired by the BattleBot “Bite Force”.

Warning! All combat robots are inherently dangerous! Handle LiPo batteries and powerful motors carefully.
