The prompt
Design a modular wearable robotic exoskeleton arm for a human. The arm should be made from separate components: a shoulder joint, upper-arm section, elbow joint, and forearm section. The upper-arm and forearm sections should be hollow shells with enough internal space for a human arm, padding, wiring, and mechanical supports. Each shell should be split lengthwise and open like a clamshell. Add a strong hinge along the rear/outer side of each shell and a secure latch or locking pin on the opposite side, allowing the wearer to open the shell, place their arm inside, close it, and lock it securely. The inner exoskeleton frame should be separate from the outer armour. The outer armour should be removable from the inner frame using strong mechanical mounting points or quick-release connections, allowing the armour to be removed for maintenance and replaced with different MK2 armour modules. The shoulder and elbow must be separate articulated joints that allow realistic arm movement. Keep the upper arm, elbow, forearm, inner frame, outer armour, hinges, and latches as separate editable CAD components rather than one fused solid. The design should be practical for a human-wearable exoskeleton and suitable for further editing in Fusion 360. Leave space for motors, servos, wiring, electronics, and mechanical hardware. Use a strong, realistic mechanical structure rather than decorative armour only.
