# useActuators

> Get all actuators with metadata

Returns a stable array of all actuators in the model with their IDs, names, and ranges.

## Signature

```tsx theme={null}
useActuators(): ActuatorInfo[]
```

## Usage

```tsx theme={null}
import { useActuators } from "mujoco-react";

function ActuatorPanel() {
  const actuators = useActuators();

  return (
    <ul>
      {actuators.map((a) => (
        <li key={a.id}>
          {a.name} (range: {a.range[0].toFixed(2)} to {a.range[1].toFixed(2)})
        </li>
      ))}
    </ul>
  );
}
```

## Return Value

```tsx theme={null}
interface ActuatorInfo {
  id: number;
  name: string;
  range: [number, number];
}
```

| Field   | Type               | Description                 |
| ------- | ------------------ | --------------------------- |
| `id`    | `number`           | Actuator index in the model |
| `name`  | `string`           | Actuator name from MJCF     |
| `range` | `[number, number]` | Control range `[min, max]`  |

## Notes

* The array is recomputed only when the model changes (e.g., after `loadScene()`)
* Returns a stable reference — safe to use in dependency arrays
* For reading/writing individual actuator values, see [`useCtrl`](/hooks/use-ctrl)
