All prices are before taxes and shipping. Packs are optional and independent; the robot is complete without any of them.
What the numbers mean in practice
-
15 motors at 25 cm and about 800 g is why the robot walks rather than poses. Every move is generated by a policy driving real joints, not by replaying an animation.
-
The 50 Hz control loop runs on the robot. Movement is not streamed from your laptop; the robot balances by itself. Your computer is for programming and training, not for keeping it upright.
-
A camera, LiDAR and two IMUs are the sensing stack the walking and balancing policies consume. Two IMUs means the robot has a sense of its own body position and its motion separately.
-
Seven moves shipped trained means the robot is useful on day one, before you write a line of code. Making your own moves is the second act, not the entry fee.
-
Roller mode is real. Clip on the Accessory pack rollers, ask for roller mode, and the robot loads the other policy and rolls.
Questions people ask about the specs
How long does the battery last? It depends how hard you drive it - walking and kicking pull more than standing around. The Charger pack exists for people who want to keep going without waiting: two spare batteries and a dual charger.
How fast can it walk? Fast enough to be fun on a desk and to need attention on the edge of one - and the speed is a policy property, which is the interesting part: train a faster gait if you want one.
Can it go up stairs? No. It is a 25 cm desk robot. It handles flat surfaces, small props, and getting back up after it falls - that recovery is one of the trained moves.
Is 25 cm the whole robot or just the body? That is the full height on its legs, duck head included.
What do I need on day one? Charge the battery, power it on, drive it with the included controller. Nothing else.
Where are the specs for the SDK side? In the documentation - what the SDK exposes, how the simulator runs and how training works. If you want to start coding, the Python SDK guide is the walking path.
