An autonomous waste-retrieval robot

GIGI

A legged robot that walks trails, beaches and race routes, finds the litter, and picks it up.

The problem

Trash everywhere.

Cleanup crews and volunteers do it by hand, on terrain wheels cannot cross. The litter comes back every day.

A marathon street covered in thousands of discarded water cups

Races

30,000

Gel wrappers and water cups left behind for every 1,500 athletes.

Beach

Every tide

The ocean washes debris ashore again, so the cleanup never ends.

Piles of bottles and litter among rocks and snow below Everest

Mountains

Too steep

Litter piles up where it is too remote for cleanup crews or sherpas.

Festivals & nightlife

Tons a night

Cleanup eats a big share of every event budget.

The solution · MVP

Off the shelf. Out in the field.

A Unitree Go2 quadruped with an SO-101 arm on its head and a bin on its back. No custom hardware to build, a low cost per site, and each robot pays back fast.
