## Achievements

- 3rd place · CAST design challenge, MAHE 2025
- Four CFRP tape-spring booms
- One drive, four spools

## One drive. Four spools.

A central spur gear turns four independent spools together, keeping the boom release coordinated.

## Keep the tape under control.

Spring-loaded tensioners press against each coil. Rollers guide the tape out as it becomes a structural boom.
