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.

Telescope Making

Make a reflecting telescope from scratch — grinding, polishing, and figuring the mirror yourself.

Grind and polish your own telescope mirror by hand, then see the sky through glass you figured.

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 Telescope Making if…

  • A genuinely profound payoff: see the sky through optics you made by hand.
  • Meditative, low-cost craft with centuries of tradition and community behind it.
  • Teaches optics and precision you can't get from buying a scope.

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.

Telescope Making

  • Figuring and testing a mirror is hard, slow, and unforgiving of impatience.
  • You need a dedicated grinding space and a way to test the surface.
  • It's a long arc — first light can be months of work away.
