Antweight
Antweights are fighting robots (think Robot Wars but tiny!), a maximum of 150g in weight and small enough to fit inside a 4" cube.
I currently compete with Eyesorasaurus, out-of-micro:trol and Tik-Tok.
Pi Wars
Pi Wars is an annual (ish) robotics competition, where teams compete in a variety of remote control and autonomous challenges.
I competed with Sky Fawkes in 2019, and am entering Townson Family Salvage in 2020.
Science Oxford
Science Oxford is an educational charity, for whom I work as Technology Projects Officer. I have built two different sets of robots to use in workshops.
