The prompt
Design a 12-DOF quadruped robot chassis for a mobile detection platform, ~450mm body length x 300mm width x 150mm body height. Lightweight frame, target total mass under 12kg including payload. Four legs, 3 servo joints per leg (hip abduction, hip flexion, knee), servo mount brackets at each joint. Include: - A forward-facing sensor bay (80mm x 60mm x 40mm) on the front of the body for an e-nose + IMS air-sampling module, with an intake vent opening facing forward - A rear compartment (120mm x 80mm x 50mm) for a hot-swappable Li-ion battery pack, accessible via a sliding or hinged panel - A central compute bay (100mm x 70mm x 30mm) for a Jetson Orin Nano board, positioned above the leg mounts for weight balance - Mounting points on top of the body for a LiDAR/depth camera module - IMU mounting point at the geometric center of the body Material: lightweight aluminum or engineering polymer frame, hollow/ribbed structure where possible to reduce mass while maintaining servo mount rigidity.
