Or give your AI the task in words. The prompt names the tools and the exact commands.

You have the MouseMouse MCP server (lucen-mcp) configured against https://api.mousemouse.ai.
Work with the robot repo lucen/boston-dynamics-spot on that hub.
1. Read its card with get_robot_card(owner, repo) and its policies with search_repos(kind="model", robot="lucen/boston-dynamics-spot").
2. To train for it, submit a run with submit_training using template ppo_mujoco and robot "lucen/boston-dynamics-spot" (the CLI equivalent is: lucen runs create --template ppo_mujoco --robot lucen/boston-dynamics-spot --executor worker).
3. Never start, stop or steer a robot: a handoff is request_deploy, and a person approves it in the Inbox.

Boston Dynamics Spot

Boston Dynamics Spot is a quadruped, shown without its arm, made by Boston Dynamics. This model comes from MuJoCo Menagerie by Google DeepMind, under the BSD-3-Clause licence. The licence text is in LICENSE.

Not made by Lucen Robotics. Listed as a reference model for simulation.

The source's own README is kept unchanged as SOURCE_README.md.

How it was set up

The files come from boston_dynamics_spot in MuJoCo Menagerie, at commit 822c2d8. The robot card was drafted from the model by lucen robot init, as in Add your robot.

The model file does not state the values below. Each one comes from the source beside it.

SettingValueWhere it comes from
Control rate50 HzPlayground spot/joystick.py ctrl_dt=0.02
Actionoffset from the default posePlayground spot/joystick.py: motor_targets = default_pose + action * action_scale
Action scale0.3Playground spot/joystick.py action_scale=0.3
What a policy sensesjoint positions, joint velocities, base angular velocity, gravity directionSpot's joint encoders and IMU
Commandforward, sideways and turning speedPlayground's joystick command (vx, vy, yaw)
Everything elseread from the model filejoint order, the home keyframe, and kp 500 / kv 40 from the MJCF's own <position> actuators (Playground's task retunes its own copy to Kp 300 / Kd 1).

The configs cited above, at the commits read:

  • Playground: MuJoCo Playground, commit 4057c14. Each robot's task file, under locomotion or manipulation, in its default_config().

No file from the source was changed. This README, the robot card and the robot's pictures are new.
