“机器人孙子”和“哥哥们”是怎样炼成的？揭秘登上春晚小品机器人的背后技术

Core Viewpoint - Beijing Songyan Power Technology Group showcased multiple robots during the CCTV Spring Festival Gala, highlighting advancements in humanoid robotics and their capabilities in performing complex tasks and dances [1][6]. Group 1: Robot Development and Features - The team completed a 1:1 replica of a humanoid robot's head in just 30 days, overcoming challenges such as adjusting head proportions and ensuring precise lip movements for speech synchronization [4][5]. - The humanoid robot features 12 degrees of freedom in the lips and utilizes a self-developed expression driving algorithm to achieve realistic movements, significantly reducing the "uncanny valley" effect [5][6]. - The "Little Bumi" robot, standing 94 cm tall and weighing approximately 17 kg, learned 21 different dance styles, showcasing its advanced training capabilities [7]. Group 2: Performance and Control - The robots were required to perform in a limited space of about 12 square meters, necessitating high precision in movement control to avoid disrupting the performance [6]. - The team developed over 300 strategies to optimize the robots' motion control, adjusting the structural design to enhance balance and agility for executing complex movements [6][7]. - The training process involved capturing movements from children to refine the robot's actions, ensuring that its running posture closely resembles that of a human [7]. Group 3: Future Prospects - The founding and core development team of Songyan Power is primarily composed of individuals born in the 1990s, indicating a youthful and innovative approach to robotics [7]. - The company envisions a future where robots will transition from stage performances to everyday household applications, reflecting a broader trend in the robotics industry [7].
