Dual-Arm Workcell

Build a self-contained Three.js 3D simulator of a dual-arm industrial workcell, with locally bundled Three.js, no CDN dependencies and an English interface. Inside a safety-fenced workshop, include CELL 07 / DUAL-ARM COOPERATION ZONE floor markings, electrical cabinets and waveform screens. Two KUKA-style six-axis robot arms should perform coordinated pick-and-place handovers between their workstations and a conveyor, with opening and closing grippers and motion trails. Use dark factory panels with fluorescent yellow-green accents. The top status bar should show SIMULATION, STATUS: RUNNING and SYSTEM LOAD, a red ESTOP button, and NIGHT, SETTINGS and LOGOUT controls. Place an AGENT panel on each side with J1 BASE, J2 SHOULDER and J3 ELBOW angle gauges, live torque curves, manual and automatic controls, TIME CONTROL and scrolling command-terminal logs. Loop the coordinated task animation and let users take manual control of either arm. Change the workcell into an automotive welding shop: the two six-axis arms become welding robots performing spot welds on both sides of a white car body, with spark particles and a blue arc glow at the torch tips; the conveyor becomes a skid line carrying car bodies, and the floor marking reads WELD LINE 03. Keep the overall layout of the safety fence, the top status bar and the two side AGENT panels.

Loop the coordinated task animation and let users take manual control of either arm. Switch all interface text to Chinese and add an annotation layer for robotics students: hovering over terms such as J1 BASE, J2 SHOULDER and J3 ELBOW shows a Chinese explanation with a small diagram of the joint's motion; the status bar and panel titles are localized into Chinese as well. The annotation layer can be toggled in the settings.
