Dexterous Hands in Robotics: A Shift from High Degrees of Freedom to Practicality
灵巧手行业正在集体做减法？
The article explores the evolving landscape of dexterous hands in robotics, noting a trend away from high degrees of freedom (DoF) toward more practical metrics like durability, cost, and operational efficiency. It highlights how industrial standards are influencing the market, with grippers and simpler hands becoming more prevalent. The text also discusses the limitations of current VLA models in controlling complex robotic hands and the role of data collection in training these systems.
