Microduck is 25 cm tall and about 800 g, with 15 motors, a camera, LiDAR and two IMUs, and a 50 Hz onboard policy loop. Seven moves come trained: standing up, sitting and standing, walking, turning, kicking, driving and grabbing.

Questions about an order go to support@microduck.homes.

Microduck is open source, and that includes the parts that make it move. The Python SDK, the simulator and the reinforcement-learning stack behind the seven shipped moves are all public, so the robot you receive is one you can retrain rather than only control.
Standing up, sitting and standing, walking, turning, kicking, driving and grabbing arrive trained. Each one is a policy, so each one can be taken apart, retrained and replaced.
Pre-orders are open on the pre-order page, with the buying FAQ on the buy page.
