 The robot's motion and action mappings, such as stopping, moving, sitting, and standing, are defined in [rosserial_node.launch](./jsk_unitree_startup/launch/rosserial_node.launch) and [lead_joystick_teleop.yaml](./jsk_unitree_startup/config/lead_joystick_teleop.yaml). These files control the robot's responses to joystick inputs and can be customized as needed.
