蔡明机器人难点在活人感

Core Viewpoint - The development of a lifelike robotic version of Cai Ming for the CCTV Spring Festival Gala showcases significant advancements in robotics technology, particularly in creating realistic facial expressions and movements [1] Group 1: Technical Challenges and Innovations - The technical team at Songyan Power faced the challenge of creating a 1:1 replica of Cai Ming, which required precise modeling and adjustments to meet the demands of live performance [1] - A total of 32 micro motors were redesigned and compactly arranged to control facial expressions, with the control frequency increased sixfold to ensure smooth transitions between expressions [1] - The team developed a custom expression generation system based on extensive video data and live performance captures, enabling the robotic figure to replicate subtle facial expressions like raising eyebrows and smiling [1] Group 2: Enhancements for Realism - During rehearsals, the team identified that the robotic figure lacked a sense of "liveliness," prompting further adjustments to include neck movements and breathing patterns to enhance realism [1] - Three additional degrees of freedom were added to the neck to allow for slight movements that align with speech and facial expressions, making the robotic figure appear more lifelike [1] - The iterative process of adjustments and rehearsals ultimately led to a robotic figure that closely resembled a real person, achieving a significant milestone in robotics for live performances [1]
