This design offers flexibility in how robot functionalities are defined and managed within your agent-based applications. + +**Agent's `skills` Parameter** + +The `skills` parameter in an agent's constructor is key to this integration: + +1. **A Single Skill Class**: This approach is suitable for skills that are relatively self-contained or have straightforward initialization requirements. + * You pass the skill *class itself* (e.g., `GreeterSkill`) directly to the agent's `skills` parameter. + * The agent then takes on the responsibility of instantiating this skill when it's invoked. This typically involves the agent providing necessary context to the skill's constructor (`__init__`), such as a `Robot` instance (or any other private instance variable) if the skill requires it. + +2. **A `SkillLibrary` Instance**: This is the preferred method for managing a collection of skills, especially when skills have dependencies, require specific configurations, or need to share parameters. + * You first define your custom skill library by inheriting from `SkillLibrary`. Then, you create and configure an *instance* of this library (e.g., `my_lib = EntertainmentSkills(robot=robot_instance)`). + * This pre-configured `SkillLibrary` instance is then passed to the agent's `skills` parameter. The library itself manages the lifecycle and provision of its contained skills. + +**Examples:** + +#### 1. Using a Single Skill Class with an Agent + +First, define your skill. For instance, a `GreeterSkill` that can deliver a configurable greeting: + +```python +class GreeterSkill(AbstractSkill): + """Greats the user with a friendly message.""" # Gives the agent better context for understanding (the more detailed the better). + + greeting: str = Field(..., description="The greating message to display.") # The field needed for the calling of the function. Your agent will also pull from the description here to gain better context. + + def __init__(self, greeting_message: Optional[str] = None, **data): + super().__init__(**data) + if greeting_message: + self.greeting = greeting_message + # Any additional skill-specific initialization can go here + + def __call__(self): + super().__call__() # Call parent's method if it contains base logic + # Implement the logic for the skill + print(self.greeting) + return f"Greeting delivered: '{self.greeting}'" +``` + +Next, register this skill *class* directly with your agent. The agent can then instantiate it, potentially with specific configurations if your agent or skill supports it (e.g., via default parameters or a more advanced setup). + +```python +agent = OpenAIAgent( + dev_name="GreetingBot", + system_query="You are a polite bot. If a user asks for a greeting, use your GreeterSkill.", + skills=GreeterSkill, # Pass the GreeterSkill CLASS + # The agent will instantiate GreeterSkill. + # If the skill had required __init__ args not provided by the agent automatically, + # this direct class passing might be insufficient without further agent logic + # or by passing a pre-configured instance (see SkillLibrary example). + # For simple skills like GreeterSkill with defaults or optional args, this works well. + model_name="gpt-4o" +) +``` +In this setup, when the `GreetingBot` agent decides to use the `GreeterSkill`, it will instantiate it. If the `GreeterSkill` were to be instantiated by the agent with a specific `greeting_message`, the agent's design would need to support passing such parameters during skill instantiation. + +#### 2. Using a `SkillLibrary` Instance with an Agent + +Define the SkillLibrary and any skills it will manage in its collection: +```python +class MovementSkillsLibrary(SkillLibrary): + """A specialized skill library containing movement and navigation related skills.""" + + def __init__(self, robot=None): + super().__init__() + self._robot = robot + + def initialize_skills(self, robot=None): + """Initialize all movement skills with the robot instance.""" + if robot: + self._robot = robot + + if not self._robot: + raise ValueError("Robot instance is required to initialize skills") + + # Initialize with all movement-related skills + self.add(Navigate(robot=self._robot)) + self.add(NavigateToGoal(robot=self._robot)) + self.add(FollowHuman(robot=self._robot)) + self.add(NavigateToObject(robot=self._robot)) + self.add(GetPose(robot=self._robot)) # Position tracking skill +``` + +Note the addision of initialized skills added to this collection above. + +Proceed to use this skill library in an Agent: + +Finally, in your main application code: +```python +# 1. Create an instance of your custom skill library, configured with the robot +my_movement_skills = MovementSkillsLibrary(robot=robot_instance) + +# 2. Pass this library INSTANCE to the agent +performing_agent = OpenAIAgent( + dev_name="ShowBot", + system_query="You are a show robot. Use your skills as directed.", + skills=my_movement_skills, # Pass the configured SkillLibrary INSTANCE + model_name="gpt-4o" +) +``` + +### Unitree Test Files +- **`tests/run_go2_ros.py`**: Tests `UnitreeROSControl(ROSControl)` initialization in `UnitreeGo2(Robot)` via direct function calls `robot.move()` and `robot.webrtc_req()` +- **`tests/simple_agent_test.py`**: Tests a simple zero-shot class `OpenAIAgent` example +- **`tests/unitree/test_webrtc_queue.py`**: Tests `ROSCommandQueue` via a 20 back-to-back WebRTC requests to the robot +- **`tests/test_planning_agent_web_interface.py`**: Tests a simple two-stage `PlanningAgent` chained to an `ExecutionAgent` with backend FastAPI interface. +- **`tests/test_unitree_agent_queries_fastapi.py`**: Tests a zero-shot `ExecutionAgent` with backend FastAPI interface. + +## Documentation + +For detailed documentation, please visit our [documentation site](#) (Coming Soon). + +## Contributing + +We welcome contributions!

You can also visualize data in Foxglove. + +If you want to also teleoperate the simulated robot run: + +```bash +uv run dimos --simulation run unitree-go2-basic --extra-module keyboard_teleop +``` + +This will also open a Keyboard Teleop window. Focus on the window and use WASD to control the robot. + +### Command center + +You can also control the robot from the `command-center` extension to Foxglove. + +First, pull the LFS file: + +```bash +git lfs pull --include="assets/dimensional.command-center-extension-0.0.1.foxe" +``` + +To install it, drag that file over the Foxglove Studio window. The extension will be installed automatically. Then, click on the "Add panel" icon on the top right and add "command-center". + +You can now click on the map to give it a travel goal, or click on "Start Keyboard Control" to teleoperate it. + +### Using `dimos` in your code + +If you want to use dimos in your own project (not the cloned repo), you can install it as a dependency: + +```bash +uv add dimos +``` + +Note, a few dependencies do not have PyPI packages and need to be installed from their Git repositories. These are only required for specific features: + +- **CLIP** and **detectron2**: Required for the Detic open-vocabulary object detector +- **contact_graspnet_pytorch**: Required for robotic grasp prediction + +You can install them with: + +```bash +uv add git+https://github.com/openai/CLIP.git +uv add git+https://github.com/dimensionalOS/contact_graspnet_pytorch.git +uv add

In this case `('image', Image)` will be connected between the two modules, but `begin_explore` will not be linked to `start_explore`. + +## Topic names + +By default, the name of the property is used to generate the topic name. So for `image`, the topic will be `/image`. + +The property name is used only if it's unique. If two modules have the same property name with different types, then both get a random topic such as `/SGVsbG8sIFdvcmxkI`. + +If you don't like the name you can always override it like in the next section. + +## Which transport is used? + +By default `LCMTransport` is used if the object supports `lcm_encode`. If it doesn't `pLCMTransport` is used (meaning "pickled LCM"). + +You can override transports with the `transports` method.

You can use `remappings` to rename module connections: + +```python +class ConnectionModule(Module): + color_image: Out[Image] # Outputs on 'color_image' + +class ProcessingModule(Module): + rgb_image: In[Image] # Expects input on 'rgb_image' + +# Without remapping, these wouldn't connect automatically +# With remapping, color_image is renamed to rgb_image +blueprint = ( + autoconnect( + ConnectionModule.blueprint(), + ProcessingModule.blueprint(), + ) + .remappings([ + (ConnectionModule, 'color_image', 'rgb_image'), + ]) +) +``` + +After remapping: +- The `color_image` output from `ConnectionModule` is treated as `rgb_image` +- It automatically connects to any module with an `rgb_image` input of type `Image` +- The topic name becomes `/rgb_image` instead of `/color_image` + +If you want to override the topic, you still have to do it manually: + +```python +blueprint +.remappings([ + (ConnectionModule, 'color_image', 'rgb_image'), +]) +.transports({ + ("rgb_image", Image): LCMTransport("/custom/rgb/image", Image), +}) +``` + +## Overriding global configuration. + +Each module can optionally take a `global_config` option in `__init__`. E.g.: + +```python +class ModuleA(Module): + + def __init__(self, global_config: GlobalConfig | None = None): + ... +``` + +The config is normally taken from .env or from environment variables. But you can specifically override the values for a specific blueprint: + +```python +blueprint = blueprint.global_config(n_dask_workers=8) +``` + +## Calling the methods of other modules + +Imagine you have this code: + +```python +class ModuleA(Module): + + @rpc + def get_time(self) -> str: + ... + +class ModuleB(Module): + def request_the_time(self) -> None: + ... +``` + +And you want to call `ModuleA.get_time` in `ModuleB.request_the_time`. + +You can do so by defining a method like `set__`. It will be called with an `RpcCall` that will call the original `ModuleA.get_time`. So you can write this: + +```python +class ModuleA(Module): + + @rpc + def get_time(self) -> str: + ... + +class ModuleB(Module): + @rpc # Note that it has to be an rpc method. + def set_ModuleA_get_time(self, rpc_call: RpcCall) -> None: + self._get_time = rpc_call + self._get_time.set_rpc(self.rpc) + + def request_the_time(self) -> None: + print(self._get_time()) +``` + +Note that `RpcCall.rpc` does not serialize, so you have to set it to the one from the module with `rpc_call.set_rpc(self.rpc)` + +## Defining skills + +Skills have to be registered with `LlmAgent.register_skills(self)`. + +```python +class SomeSkill(Module): + + @skill + def some_skill(self) -> None: + ... + + @rpc + def set_LlmAgent_register_skills(self, register_skills: RpcCall) -> None: + register_skills.set_rpc(self.rpc) + register_skills(RPCClient(self, self.__class__)) + + #
