Built-in motion services, firmware and policy weights are not licensed by this repository. Low-level commands can be hazardous and require vendor safety procedures.、artifact_id: unitree-sdk2-python:b2；artifact_type: official_python_sdk_examples；url: https://github.com/unitreerobotics/unitree_sdk2_python；model_specific_evidence_url: https://github.com/unitreerobotics/unitree_sdk2_python/tree/master/example/b2；applies_to: B2 only through explicit example/b2 camera, high-level and low-level paths and the unitree_sdk2py/b2 package at the verified commit；verified_access: 是；verified_ref: e4cd91f051aaa77a70600e3d2bf7f50889db1980；verified_ref_date: 2026-07-13T06:54:01Z；last_verified_at: 2026-07-19；license_spdx: BSD-3-Clause；license_url: https://github.com/unitreerobotics/unitree_sdk2_python/blob/master/LICENSE；contents: B2-specific camera capture, OpenCV, high-level sport-client and low-level stand examples.；dependencies: Python >= 3.8、CycloneDDS == 0.10.2、numpy、opencv-python；hardware_requirements: Physical examples require a compatible B2 and configured network interface、Camera examples require access to the B2 camera service and a display for the OpenCV viewer；limits: Examples depend on vendor robot services and network configuration. No policy weights, production autonomy stack or general B2-W compatibility is inferred from the B2 path.、artifact_id: unitree-ros2:b2；artifact_type: official_ros2_examples；url: https://github.com/unitreerobotics/unitree_ros2；model_specific_evidence_url: https://github.com/unitreerobotics/unitree_ros2/tree/master/example/src/src/b2；applies_to: B2 only through explicit B2 README support and example/src/src/b2 targets at the verified commit；verified_access: 是；verified_ref: 668d1ec5a05d1c38d3306bdca7d59f2ba3581a88；verified_ref_date: 2026-07-02T12:45:43Z；last_verified_at: 2026-07-19；license_spdx: BSD-3-Clause；license_url: https://github.com/unitreerobotics/unitree_ros2/blob/master/LICENSE；contents: B2 stand and sport-client examples plus DDS message and ROS 2 integration instructions.；dependencies: Ubuntu 20.04 with ROS 2 Foxy or Ubuntu 22.04 with ROS 2 Humble、CycloneDDS 0.10.2 for the documented Foxy flow、rmw_cyclonedds_cpp、rosidl-generator-dds-idl、yaml-cpp、colcon；hardware_requirements: A development computer with Ethernet for physical operation、Compatible B2 for real-robot topics and control; loopback can be used for non-robot setup；limits: The repository provides integration and examples, not a complete navigation or inspection application. Network-interface and ROS environment setup are manual; low-level control requires safety review.、artifact_id: unitree-mujoco:b2；artifact_type: official_mujoco_model_and_low_level_simulator；url: https://github.com/unitreerobotics/unitree_mujoco；model_specific_evidence_url: https://github.com/unitreerobotics/unitree_mujoco/tree/main/unitree_robots/b2；applies_to: B2 only through the explicit unitree_robots/b2 MJCF, scene and mesh assets at the verified commit；verified_access: 是；verified_ref: ae6a8403e272733e9996ef59990880330496177f；verified_ref_date: 2026-06-04T13:10:20Z；last_verified_at: 2026-07-19；license_spdx: BSD-3-Clause；license_url: https://github.com/unitreerobotics/unitree_mujoco/blob/main/LICENSE；contents: B2 MJCF model, meshes, standard and terrain scenes for the Unitree SDK2-compatible low-level simulator.；dependencies: MuJoCo 3.3.6 in the documented C++ setup、unitree_sdk2 for C++ or unitree_sdk2_python for Python、yaml-cpp、spdlog、Boost、GLFW3、pygame for optional Python joystick；hardware_requirements: No robot is required for simulation、Physical sim-to-real use requires a compatible B2 and configured Ethernet interface、GPU requirements are not quantified by the repository；limits: The repository explicitly says the current simulator supports low-level development mainly for sim-to-real verification. Its documented stand/sim-to-real sample is Go2, so B2 model assets do not establish a complete B2 real-deployment example or validated sim-to-real performance. No separate quantitative fidelity or sim-to-real loss is reported.
冲突证据: Portfolio article is not a stock, shipment or independent field-performance ledger.
未决问题: Current B2 variant availability and delivery require exact store or sales confirmation.
