## Training with KSIM

```python
from ksim.robots.kbot import KBotConfig
from ksim import PPOTask

class KBotWalking(PPOTask):
    robot = KBotConfig(
        model_path="kbot-headless.mjcf",
        joint_names=KBotConfig.DEFAULT_JOINTS,
        actuator_config={
            "kp": 100.0,
            "kd": 10.0,
            "torque_limit": 40.0,
        }
    )
