robust and flexible machine dog body design

Generate a robotic dog body structure with the following functions: Design a robust and flexible robotic dog shape with good mobility and stability, capable of adapting to different home environment terrains. Sensor system: Includes high-precision environmental perception sensors (such as LiDAR, ultrasonic sensors, etc.) for obstacle detection and environmental modeling; non-invasive biometric sensors for vital sign monitoring; cameras for image recognition and home surveillance; as well as various sensors such as tactile sensors, light sensors, and sound sensors to comprehensively collect information about various environmental conditions and user interaction. Actuator system: Equipped with mechanical arms, grippers, and other devices for handling objects, opening and closing doors, etc.; features a stable walking drive system capable of precise movement and turning; includes built-in vibrators, lighting modules, etc. for alerting the hearing impaired; and also includes a voice interaction module (microphone, speaker) for voice recognition and synthesis.
