Pato Robô · AI bipedal robot kit · 14+A duck that learns to walk. And you learn with it.
Semi-assembled bipedal robot kit with reinforcement learning. You build the legs, calibrate the servos, train in simulation and watch the policy run on the real robot. Assembled in Leiria, Portugal.
What is in the box
We do not just sell the robot. We sell the robot plus the path you walk with it.
Semi-assembled kit
Torso and head assembled; you build the legs and calibrate the 14 servos.
Pre-loaded policies
Walk, sit/stand, crouch, kick and fall recovery, trained by us for this robot. Gait variations we publish on the Hub arrive as updates.
Game controller
Drive the duck from day one, before training anything.
Course and community
Guided path in Portuguese: simulation, RL training and sim2real. In-person workshops in Leiria.
The path
Three stages. Each ends with the duck doing something it could not do before.
Build and calibrate
Legs, Feetech servos, wiring. At the end the duck stands and answers the controller with our policies.
Simulate and train
MuJoCo + PPO on an NVIDIA GPU: your own PC or a cloud machine. Change the reward, train a new gait, compare it with ours.
Sim2real
Export the policy, run it on the onboard Radxa and see what simulation did not tell you. Then back to 02.
Specifications
Based on Open Duck Mini v2 by Antoine Pirrone and the Microduck software by Pollen Robotics / Hugging Face. All Apache-2.0. No black box.

Timeline
Questions and terms
What happens to the deposit?
It secures your kit in batch 1 and is deducted from the final price: at shipping you pay the remaining €400. If we cannot build your duck for delivery, we return the deposit in full. Your statutory consumer rights, including the 14-day right of withdrawal for online purchases, are not affected.
What if there are not enough reservations?
We only buy parts for kits already reserved, so there is no idle stock. With fewer than 20 deposits on 1 November we close a batch of 30 at the same price and deliver in January — or refund your deposit, your choice.
When do I pay the remaining €400?
When the kit ships. You get a Stripe link by email; no payment, no shipping.
I reserved after 1 November. Do I get it before Christmas?
You get the Christmas box before the 23rd: printed shell, course access and a voucher. The full kit arrives in January, at the €499 launch price.
Is it a toy?
No. It is educational material for 14+, with 7.4 V servos and a lithium battery. Batch 1 ships with a declaration of conformity based on pre-certified modules; EMC testing closes in batch 2.
Do I need to know how to code?
Not to build it and use the included policies. For the training path, basic Python is enough — the course starts there.
Can I use the CAD and software?
Yes. The robot is based on Open Duck Mini v2 (Antoine Pirrone) and the Microduck software (Pollen Robotics), both Apache-2.0. Print parts, modify and publish, keeping the licence and credits.
