# `BB.LiveView.CommandRobot`
[🔗](https://github.com/beam-bots/bb_liveview/blob/main/test/support/command_robot.ex#L21)

A minimal robot exposing a single continuous command, for dashboard tests.

# `child_spec`

```elixir
@spec child_spec(Keyword.t()) :: Supervisor.child_spec()
```

Returns a child specification for starting this robot under a supervisor.

# `robot`

```elixir
@spec robot() :: BB.Robot.t()
```

Returns the optimised robot representation.

This struct is built at compile-time from the DSL definition and contains:
- All physical values converted to SI base units (floats)
- Flat maps for O(1) lookup of links, joints, sensors, and actuators
- Pre-computed topology metadata for efficient traversal

## Examples

    robot = Elixir.BB.LiveView.CommandRobot.robot()
    {:ok, link} = BB.Robot.get_link(robot, :base_link)
    {:ok, joint} = BB.Robot.get_joint(robot, :shoulder)

# `run_forever`

```elixir
@spec run_forever(keyword()) :: {:ok, pid()} | {:error, term()}
```

Execute the `run_forever` command.

## Returns

- `{:ok, pid()}` - Command started, use `BB.Command.await/2` for the result
- `{:error, term()}` - Command could not be started

## Example

    {:ok, cmd} = run_forever(goal_args)
    {:ok, result} = BB.Command.await(cmd)

# `start_link`

```elixir
@spec start_link(Keyword.t()) :: Supervisor.on_start()
```

Starts the robot's supervision tree.

## Options

All options are passed through to sensor and actuator child processes.
