Group 1 - The core idea of the article revolves around the development of a flexible robotic arm, Mawarm, and the HEART series robots by Westlake University, which aim to enhance human-robot interaction through a revolutionary technology that combines rigidity and flexibility [2][3] - Mawarm's mechanical arm utilizes a programmable pneumatic system to control the stiffness of its internal structure, allowing it to adapt its "softness" or "hardness" based on the task at hand, ensuring precision in regular operations while providing safety during collisions by softening instantly [2] - The founder of Westlake Interactive, Jiang Hanqing, emphasizes the innovative design of mechanical metamaterials, which allows the robotic arm to change its stiffness dynamically, similar to how vacuum-packed rice behaves when air is released [2] Group 2 - The target market for the HEART series robots is the elderly care and service robot sector, addressing the significant shortage of caregivers in China, where the population over 60 exceeds 280 million [3] - The HEART series robots are designed to provide safe and reliable solutions in scenarios such as elderly care, rehabilitation assistance, and material delivery, with the ability to sense human touch and soften their actions to prevent accidental injuries [3] - Jiang Hanqing believes that the essence of technology is to create needs that humans never imagined, positioning future robots as empathetic partners rather than cold metal replacements [4]
