Customize your robot.
One drivetrain, a front intake, and one shared shooter or separate pollen and nectar shooters. Use meters, kilograms, seconds, and degrees. Your GLB model is appearance only; the server uses the declared body box.
These limits do not certify a real robot as competition legal.
- Size: up to 18 × 18 × 18 inches; mass: 3–40 kg.
- Drive: up to 2 m/s; turn: up to 180°/s.
- Ball launch: up to 20 m/s; hold at most 4 balls.
- Shot delay: 0–5 s (default 0); at least 0.1 s recovery and 0.15 s between shots. Dual shooters share the firing interval.
- Static 3D model: GLB up to 5 MB; no scripts or external assets.
Switching presets keeps your saved custom robot. Finish Customization saves these settings as your custom robot.
Up to 5 MB. Static geometry, colors, no textures or extensions. Export +Y up, +X forward. Models are visible and downloadable by other players.
Positions use the robot's center: positive forward and left, with height measured from the floor. The intake stays at the front edge; keep shooter positions within the body.
