TX: robotic-arm.md — composed prompt

A desk-mounted robotic arm with at least four articulated joints, posed mid-reach toward a small object on the desk — but not an industrial catalog part. This arm is generatively designed: its metal frame has the parametric, "AI-optimized" look of topology-optimized engineering — organic load-bearing branches, smooth bone-like transitions, lattice or voronoi-style cutouts where material was removed because the algorithm decided nothing needed to be there. Every strut should look grown to carry its exact load, not extruded.

Over that frame, a second material layer: woven technical fabric. Tensioned textile sleeves and panels — visible weave pattern, carbon-fiber or ballistic-cloth character — wrap sections of the segments over the optimized metal skeleton, so the arm reads as engineered musculature over engineered bone. The interplay of the two materials (taut woven fiber against machined/printed alloy) is the material centerpiece.

The manipulator: a three-clawed gripper at the wrist — three fingers in radial symmetry, each with the same optimized-lattice construction in miniature, posed partly open toward the target object. The gripper connects to the forearm through corrugated hose: flexible ribbed tubing gathered at the wrist, running back along the arm as its visible service umbilical (power, data, pneumatics), routed and clipped like it was engineered, not draped.

The mechanics must still look like they could actually work: visible rotation axes at every joint, with actuators, cable runs, or tendon-like elements explaining how each segment moves; segments tapering plausibly from a heavy base to the fine three-claw head. The pose must be believable for the joint layout: no segment intersecting another, no joint bent in a way its geometry couldn't allow.
