Core Viewpoint - The article discusses the evolution of dexterous hands in humanoid robots, emphasizing the transition from morphological mimicry to functional mimicry, highlighting the need for high physical dexterity, multimodal perception, and intelligent decision-making capabilities in these robotic hands [2][5]. Group 1: Key Features of Dexterous Hands - A good research dexterous hand should possess three core features: high physical dexterity (IOD), multimodal perception ability (IOS), and intelligent decision-making potential (IOI) [2]. Group 2: Transmission Solutions - The current transmission solutions for dexterous hands are dominated by three main types: - Linkage transmission, which is rigid and precise but lacks high degrees of freedom [3]. - Gear transmission, which is compact and controllable but limited in force transmission efficiency and passive compliance [3]. - Tendon-driven (cable-driven) systems, favored by companies like Tesla and Shadow Hand, are lightweight and allow for natural passive compliance but face engineering challenges such as friction loss and complex system integration [3]. Group 3: Challenges in Key Hardware - The collaboration between tactile sensors and multi-degree-of-freedom joints is a critical bottleneck for dexterous operation. Existing capacitive or resistive sensors struggle with spatial density, signal drift, and environmental sensitivity, making it difficult to replicate human-level contact topology perception [3]. - The design of high-degree-of-freedom joints encounters a trade-off between performance, cost, and reliability, where increased degrees of freedom lead to more complex drive and transmission systems, resulting in higher failure rates and shorter lifespans [3]. Group 4: Degree of Freedom Debate - The industry is moving away from a fervent "degree of freedom competition" towards a rational pursuit of a "multi-dimensional system balance." While a 42-degree-of-freedom research hand exceeds the human hand's limit (approximately 27 DoF), its practical engineering viability remains to be explored [4]. - The trend is to create a "hexagonal warrior" that optimizes strength, speed, size, weight, lifespan, degrees of freedom, and structural strength [4]. Group 5: Future of Dexterous Hands vs. Grippers - In the short term, two-finger or three-finger grippers dominate structured industrial scenarios due to their low cost, stable control, and high reliability, with some users claiming they can handle 95% of tasks [4]. - However, in the long term, non-structured environments such as home services, medical care, and precision assembly will require the versatility, flexible object handling, and multimodal grasping capabilities that grippers may not provide [4]. Group 6: Industry Evolution - As the industry shifts from "mass production illusion" to "application vision," those that can bridge the "hand-eye-brain" loop, achieve soft-hard collaboration, and build a developer ecosystem will likely become the foundational infrastructure of the embodied intelligence era [5].
