The prompt
Generate a complete 6-axis articulated robotic arm assembly comprising a rectangular base housing dimensions 220 mm long by 180 mm wide with four 6.5 mm corner mounting holes, an internal 3 kg counterweight cavity, a front rocker switch cutout, a 5mm LED indicator bezel, engraved "KG" lettering on the side panels, an engraved Bill of Materials (BOM) text layout on the base surface, and a rotating turret platform. The arm structure must consist of an upper arm link and a forearm link each measuring 400 mm in center-to-center length to achieve an 800 mm total reach excluding the hand, with integrated internal routing channels ($10\text{ mm} \times 8\text{ mm}$) and pivot joints sized to house SG90 micro servos ($31.8\text{ mm} \times 12.0\text{ mm} \times 32.0\text{ mm}$). Each major rotational axis must incorporate a 3D-printable modular single-stage planetary gearbox with a 15-tooth sun gear and a 63-tooth ring gear yielding a 5.2:1 torque-multiplication ratio. The end-effector assembly must feature a parallel-jaw grapple driven by a high-torque micro servo coupled with a sector gear train and high-friction grip pads. Include a matching handheld remote control unit housing 6 potentiometer knob cutouts, an ergonomic grip, and internal controller mounting space. All mating parts must incorporate standard $0.2\text{ mm}$ radial clearances for 3D printing and precise mechanical assembly. Use the image attached as a reference design for the physical look and aesthetic.
