The prompt
Got you — **detailed enough for an AI CAD tool, but not a giant wall of text**. Create a **single fully connected APEX V2 humanoid mechanical skeleton**, designed as an original biomimetic robotic system inspired by human biomechanics. ### BODY Connect the entire body mechanically: **head, neck, segmented spine, shoulders, upper arms, elbows, forearms, wrists, hands, fingers, thumbs, pelvis, hips, thighs, knees, lower legs, ankles and feet.** ### JOINTS * **Neck:** compact 3-axis pitch/yaw/roll mechanism. * **Spine:** 6–10 linked vertebra-like segments with distributed flexion, extension, lateral bending and rotation. * **Shoulders:** floating 3-axis spherical mechanisms with controlled translation. * **Elbows:** variable-axis multi-link hinges for flexion/extension. * **Wrists:** compact nested gimbals providing flexion, deviation and rotation. * **Fingers:** three-segment tendon-driven mechanisms with articulated pivots and compliant fingertips. * **Thumbs:** multi-link opposable mechanisms with flexion, extension, abduction, adduction and rotation. * **Hips:** compact 3-axis spherical mechanisms. * **Knees:** multi-link rolling/sliding mechanisms with changing rotation centers and controlled rotation. * **Ankles:** compliant parallel-link mechanisms providing pitch, roll and limited rotation. ### MECHANICAL SYSTEM Integrate **precision bearings, shafts, linkage arms, spherical joints, modular actuator mounts, mechanical travel stops, compliance elements, replaceable joint cartridges, sensor mounts and cable/tendon channels**. Use realistic mechanical clearances and ensure every joint connects correctly to the neighboring limb structure. ### MATERIALS Use **7075-T6 aluminum** for lightweight frames and housings, **Ti-6Al-4V titanium** for selected high-load lightweight components, **17-4PH stainless steel** for shafts/pins, **PEEK** for low-friction bushings, **carbon-fiber composite** for lightweight limb structures, and **elastomers** for controlled compliance and damping. ### SENSING & ACTUATION Provide mounting locations for **absolute encoders, torque/load sensors, IMUs, temperature sensors, electric rotary actuators, transmissions and series-elastic elements**. Keep actuator interfaces modular and separate from the primary structural bearings. ### CAD STYLE Create a **high-detail engineering CAD assembly**, not a sci-fi shell. Show internal mechanisms where possible, realistic fasteners, bearing seats, linkage connections, removable covers, joint axes, cable routing, service access and manufacturable part geometry. Output **one complete articulated full-body assembly**, with an **exploded technical view showing all major joint mechanisms and materials**. v
