Combat Robotics

Engineer a robot's drive, weapon, and armour, then battle in the arena.

Design, build, and drive a fighting robot, then send it into the arena against another.

Retrocomputing

Restore, repair, and program vintage computers — bringing classic hardware back to life.

Restore and program vintage computers — recap a dead board and boot a machine from 1984.

Which is right for you?

Choose Combat Robotics if…

  • A complete, hands-on engineering education across motors, power, radio, and structure.
  • The arena adrenaline and a genuinely friendly, helpful community.
  • Cheap entry classes (antweight/beetleweight) keep the first bot affordable.

Choose Retrocomputing if…

  • Bare-metal understanding of how computers actually work, with real nostalgia.
  • A revived machine is a tangible, usable, genuinely cool result.
  • Active communities document nearly every machine and fault.

Before you commit

Combat Robotics

  • Your robot will get destroyed, so repair and iteration are the real hobby.
  • Ongoing costs add up: spare parts, batteries, and travel to events.
  • A steep start across several disciplines at once, and a workshop to build in.

Retrocomputing

  • Old hardware is flaky and parts can be scarce or pricey.
  • Basic soldering and patient fault-finding are part of the deal.
  • Storing machines and spares takes more space than you'd think.
