Delivered to United States: the import estimate (machine plus freight, Sales tax (0%), robot duty, and broker), or a seller in your own market where one lists the machine for less. Accessories excluded. Check configuration and request a seller quote on each robot's datasheet.
About 40% on China-origin collected today: the 2.5% MFN base, 25% Section 301 List 1, and the 12.5% Section 301 forced-labor duty effective 24 Jul 2026 with no expiry. It began the same morning the 10% Section 122 surcharge lapsed, so the total rose from about 37.5% rather than falling to 27.5%. Confirm the live rate before ordering.

| Out of the box | Among the most functional at its price: walks day one, remote and app control, demo motions, voice/LLM interaction, and a proven autonomous soccer stack (RoboCup 2025 KidSize champion lineage). Widely used for demos with zero code. | Nothing autonomous on power-up. ToddlerBot is a research kit: out of the box you get a 3D-printed bipedal chassis driven by DYNAMIXEL servos plus a fully pip-installable Python codebase. Its headline feature is a high-fidelity digital twin with plug-and-play zero-point calibration and motor system identification, so a policy trained in MuJoCo simulation transfers zero-shot to the real robot. After assembly and calibration you can run the provided policies (walking at up to 0.25 m/s, push-ups, pull-ups, wagon pushing, bimanual and full-body manipulation) or teleoperate it with a handheld gaming PC, but there is no app, voice assistant, or ready-made behavior for a non-programmer. | Same remote-control walking and voice/vision demos as the consumer R1, plus it is immediately developable: high- and low-level programming, ROS2, and Isaac Sim support. Nothing autonomous until you build it. |
| Development access | Open across ALL tiers (unlike Unitree R1): Python/C++ APIs, ROS 2, Booster Studio IDE, open-source RoboCup framework, and sim support (Isaac, MuJoCo, Webots, Gazebo). Tiers differ by compute, not by SDK lock. | Entirely open-source Python stack (hshi74/toddlerbot on GitHub). Codebase is MIT-licensed (commercial use allowed) and covers low-level control, RL training, diffusion-policy training, and real-world deployment; built on MuJoCo with MJX for accelerated training. The mechanical design files (Onshape, STLs) are CC BY-NC-SA 4.0, so the hardware design is non-commercial only. Full API docs, assembly manual, and bill of materials are published. | Fully unlocked (the only R1 tier with secondary development): high/low-level APIs, ROS2, and configuration-dependent onboard compute. Confirm the module with the seller. |
| Best for | Schools, RoboCup teams, and labs that want an affordable, fully open, competition-proven development platform. | Robotics and embodied-AI researchers, university labs, and serious makers who want an affordable, reproducible, fully open bipedal platform to develop and test sim-to-real reinforcement-learning and imitation-learning policies (loco-manipulation), not buyers wanting a finished consumer robot. | Universities and startups that want a compact programmable humanoid with configurable compute. |

K1
In the box
- Robot (fully assembled)
- Remote control
- Charger
- Documentation
- Transport case (Edu/Pro tiers)
- 6 months Doubao LLM access (China config)
Not included
- Hands or grippers (arms are 4-DOF with no end effector)
- Longer warranty on lower tiers (3 months on Geek)
- Charging dock
ToddlerBot
In the box
- ROBOTIS Bundle Kit ($4,335.51): the full set of DYNAMIXEL smart servos that actuate the robot (2x 2XC430-W250-T, 6x 2XL430-W250-T, 8x XC330-T288-T, 4x XC430-T240BB-T, 4x XM430-W210-T), plus HN11-I101 and HN12-I101 horn/bracket sets, a U2D2 USB communication controller and U2D2 PHB power set
- Alternatively, WowRobo ToddlerBot 2.0 assembled version ($4,299): all structural components, servos, and sensors, assembled and tested as a chassis
Not included
- NVIDIA Jetson Orin NX 16GB onboard computer (must be purchased separately, this is ~half the cost of a full build)
- Lithium battery pack
- WiFi module
- The 3D-printed structural shells and end-effectors (the ROBOTIS kit is DYNAMIXEL parts ONLY; you 3D print the body yourself from the open Onshape/STL files, ~21 min print time per repair part)
- Cameras, IMU, speaker, and microphones if buying the bare ROBOTIS parts kit
- A teleoperation controller (a Steam Deck or ROG Ally X handheld PC used to drive it)
- Any autonomy: it ships as hardware plus open-source code, not a robot that does anything on power-up
- Commercial-use rights to the mechanical design (design files are CC BY-NC-SA 4.0, non-commercial; only the software is MIT-licensed)
- Vendor technical support or a warranty in the consumer-product sense; support is a research community (Discord/WeChat)
R1 EDU
In the box
- R1 EDU robot (26 joints in the base specification)
- Battery, controller, charger
- Full SDK access
Not included
- Dexterous hands on lower tiers
- Compute module unless confirmed in the seller configuration
- Spare battery
- A training workstation
- Import duties/VAT buying direct
