# Unitree H1_2

`UnitreeH12Cfg` configures the bundled 27-joint Unitree H1_2 humanoid,
including its floating base, standing pose and simulation PD drive defaults.

  <p><b>Unitree H1_2 in the default joint pose</b></p>
</div>

## Usage

```python
from embodichain.lab.sim import SimulationManager, SimulationManagerCfg
from embodichain_robots import UnitreeH12Cfg

sim = SimulationManager(SimulationManagerCfg(headless=True, num_envs=1))
cfg = UnitreeH12Cfg.from_dict({})
robot = sim.add_robot(cfg=cfg)
```

The catalog ID is also accepted by the shared preview command:

```bash
embodichain preview-robot --robot UnitreeH1_2
```
