Low-Profile Telescopic Inspection Robot with Detachable Walking Head

Create a complete 2D CAD concept drawing of an ultra-low-profile robotic inspection system for refinery and petrochemical environments. The robot must have a very low rectangular chassis designed to travel underneath pumps, compressors, pipe racks and other equipment. Overall concept dimensions: approximately 400 mm long, 250 mm wide and 40–60 mm high excluding wheels. Use four compact wheels positioned near the corners of the chassis. At the center of the robot, include a multi-stage telescopic inspection mast. The mast must fully retract into or closely along the low-profile chassis during travel and extend vertically to approximately 2 meters for inspection. Show multiple nested telescopic sections. At the top of the telescopic mast, include a detachable micro-inspection head. The inspection head should be approximately 120 mm long, 80 mm wide and 50–60 mm high. The head must function as both the mast-mounted sensor head and a separate miniature walking inspection robot. The detachable inspection head must have four very small articulated robotic legs that remain folded close to the body while mounted on the mast. When detached, the four legs deploy outward and downward, allowing the head to walk or crawl into narrow blind areas behind pipes, valves, flanges, underneath equipment and around structural obstructions. The detachable head should include a front inspection camera, thermal camera, LED inspection lights and small side cameras. Keep the sensor housings compact and mechanically realistic. Include a mechanical docking interface between the telescopic mast and detachable inspection head so the head can lock onto the mast, detach for independent inspection and later return and reconnect. The main robot should include four-wheel mobility, a low central battery/electronics compartment and small deployable stabilizing feet to stabilize the chassis while the mast is fully extended. Generate clean engineering CAD linework rather than artistic rendering. Include separate orthographic views: 1. Top view of complete robot 2. Side view with mast fully retracted 3. Side view with mast fully extended 4. Front view 5. Detachable inspection head with legs folded 6. Detachable inspection head with legs deployed 7. Exploded or separated view showing detachable head above mast docking interface Use mechanical engineering proportions, straight construction geometry and separate layers for chassis, wheels, mast, inspection head, legs, sensors, stabilizers and dimensions. Do not include refinery background scenery, people, logos or decorative elements. Focus only on the robot and its mechanical components. Make the drawing suitable as an early conceptual CAD layout for later development in Onshape or AutoCAD.
