4 degrees of freedom, 94 sensors: Unitree once again showcases its super flexible robotic hand, but who is more advanced compared to Musk's Optimus? On April 1st, Unitree Technology, famous both in China and worldwide, displayed the company's newly developed super flexible robotic hand. In the video, the robot can perform actions such as playing poker, solving a Rubik's Cube, catching fruit, flipping books, and demonstrating the flexible movements of ten fingers. According to the video introduction, the main four fingers of this mechanical hand each have 4 degrees of freedom, and one palm has 94 tactile sensors. This means that a single hand has 16 degrees of freedom. If we add the thumb and the palm, it should be around 20. The degree of freedom is actually close to the latest hand technology of Musk's Optimus, which has 22 degrees of freedom per hand and can also demonstrate complex actions like catching a ball. However, please note that in the Optimus video, only one hand has 22 degrees of freedom, while the other is still an older model with only 11 degrees of freedom. In contrast, Unitree's hands each have around 20 degrees of freedom, and the increased flexibility of both hands further enhances task extensibility. A human hand has 27 degrees of freedom, and Unitree's robotic hand is rapidly approaching human levels. From the background, this robot body is still the G1 model. It seems that Unitree's approach is to develop the flexibility of various parts of the robot's limbs and hands separately, then integrate them together. Following this path, perhaps we will see embodied intelligent robots that fully simulate human movements...
