Unitree Robotics recently unveiled its latest creation, the Unitree Dex5 dexterous hand. According to the official announcement, this high-performance hand boasts an impressive 20 degrees of freedom (16 active and 4 passive) and 94 sensitive contact points, demonstrating exceptional dexterity and perception.
In terms of degrees of freedom, the Dex5 thumb has 4 active degrees of freedom, while the other four fingers each have 4 degrees of freedom (3 active and 1 passive). Importantly, all Dex5 joints support smooth back-drivability (direct intrinsic force control), enabling more precise force control and natural interaction during operation.
Demonstration videos released by Unitree Robotics show a robot equipped with the Dex5 dexterous hand effortlessly performing intricate tasks such as picking up oranges, playing cards, and solving a Rubik's Cube, highlighting its potential for complex manipulations.
However, information on the Dex5 dexterous hand is not yet available on the Unitree Robotics website. Currently, their "dexterous hand" product line only features the Dex3-1 three-finger dexterous hand, which has 7 degrees of freedom and 7 moving joints. The launch of the Dex5 undoubtedly marks a significant breakthrough for Unitree Robotics in the field of robotic dexterous manipulation.
