I love competing in Combat Robotics, The sport is better known as Battlebots. Below are a few of my robots. Follow along at https://www.instagram.com/teamfoodfight/ to see some behind the scene shots.
An antweight (1lb) vertical spinner. Custom built from the ground up this has been my main combat robot. Pizza Slicer won bronze at its first ever Robogames competition. Robogames is the largest combat robotics competition in the world.

An antweight drum bot. Hotdog Roller is a fun bot and does extremely well in rumbles when facing multiple robots at once.
A 3D printed antweight, that competes in the plastic class. This class is designs to make fighting robots more accessible, by limiting the materials and construction techniques. For new comers this is the class that I recommend they start off with.
