春晚“机器人版蔡明”亮相背后，这家年轻团队如何注入“灵魂”

Core Viewpoint - The introduction of a humanoid robot in the CCTV Spring Festival Gala's skit "Grandma's Favorite" marks a significant advancement in robotics, showcasing the capabilities of the Beijing-based team Songyan Dynamics in creating lifelike robotic performances [1][3]. Group 1: Technological Innovations - The humanoid robot was developed over two years and completed a 1:1 replica in just 30 days, demonstrating the team's efficiency and technical prowess [3]. - The robot's facial features were enhanced using platinum silicone mixed with high polymer materials, allowing for improved natural movement and durability [3]. - A total of 32 motors were integrated into the robot's face, with 12 dedicated to mouth movements, significantly improving the flexibility of lip movements [3][4]. Group 2: Performance and Interaction - To address the "uncanny valley" effect, the team created a multi-modal expression model that coordinates mouth shapes, facial expressions, eye movements, neck postures, and gestures [4]. - The robot was designed to exhibit breathing movements and coordinated actions with its arms and neck, enhancing the illusion of lifelike behavior [4]. - The performance required precise movement control, as the robots had to operate within a limited space of approximately 12 square meters, necessitating high accuracy in their actions [5]. Group 3: Training and Development - The robot "Little Bumi" learned 21 different dance styles, showcasing the team's commitment to continuous improvement and adaptation [7]. - The training involved capturing movements from children of various ages, which were then redirected to the robot for reinforcement learning [7]. - The Beijing Economic and Information Technology Bureau reported that the city supports 12 categories of 200 innovative robotic products, indicating a robust local robotics industry [7].
