We need a “Holographic Simulator” to demonstrate the operating state of a robotic arm. The scene should be presented in a 2D orthographic view with a holographic projection aesthetic, featuring scan lines and subtle jitter; the jitter amplitude should respond in real time to the audio spectrum intensity available in the browser (from music playback or microphone input). The system will loop the robotic arm’s motion sequence and calculate an “efficiency score” based on the duration and stability of a complete cycle (e.g., grasp → move → release), displaying it in the UI. Implementation can use Three.js to load the robotic arm model, with custom GLSL shaders to achieve the holographic scan-line and noise flicker effects.
