用符号化动作编码让机械臂精准传递戏曲文化语义
Translating Cultural Choreography from Humanoid Forms to Robotic Arm
- 提出三阶段流程，将戏曲姿势转化为可移植的关节空间符号
- 在六自由度机械臂上实现动作时序与文化可读性双重还原
- 适合跨模态文化传承与非人形机器人艺术创作
机械臂编排常仅复现轨迹而丢失文化内涵。本研究检验了基于关节空间兼容符号记法的动作语义迁移是否能在六自由度机械臂上保持语义保真，并具备跨形态可移植性。提出ROPERA三阶段流程：编码文化编码姿势、组合符号序列、解码为伺服指令。以昆曲《牡丹亭》片段为实验材料，包含基于语料库的姿态选取、符号评分、直接关节角执行，以及结合灯光绘画与服饰色彩的视觉层。专家与观众评估均显示动作时序准确且文化可辨识。研究指向非人类中心的文化保存与可移植创作流程。未来将设计舞蹈引导的过渡路径，拓展记法至带触觉、音乐与空间提示的移动行为，并测试跨平台可移植性。
原文摘要 · Abstract (English)
Robotic arm choreography often reproduces trajectories while missing cultural semantics. This study examines whether symbolic posture transfer with joint space compatible notation can preserve semantic fidelity on a six-degree-of-freedom arm and remain portable across morphologies. We implement ROPERA, a three-stage pipeline for encoding culturally codified postures, composing symbolic sequences, and decoding to servo commands. A scene from Kunqu opera, \textit{The Peony Pavilion}, serves as the material for evaluation. The procedure includes corpus-based posture selection, symbolic scoring, direct joint angle execution, and a visual layer with light painting and costume-informed colors. Results indicate reproducible execution with intended timing and cultural legibility reported by experts and audiences. The study points to non-anthropocentric cultural preservation and portable authoring workflows. Future work will design dance-informed transition profiles, extend the notation to locomotion with haptic, musical, and spatial cues, and test portability across platforms.
