The fall is funny, but it isn't the story. The story is how they learned to walk at all : thousands of virtual copies trained in a world that an AI agent built on a laptop.

What a Microduck is

A tiny walking robot from Pollen Robotics , the robotics team Hugging Face bought in April 2025.

About 25 cm (10 in) tall , under 2 lb.

15 motors (legs, neck, head), a front camera, a depth sensor and two IMUs.

Walks, sits, crouches, catches its balance when pushed, and gets back up on its own.…
