On April 25, it was learned that Tencent Robotics X Lab announced the latest progress in robot research, demonstrated its achievements in the field of dexterous operation for the first time, and launched its self-developed robot dexterous hand TRX-Hand and robotic arm TRX-Arm.

According to reports, the dexterous hand TRX-Hand has the same flexible operation ability as a human hand, can adapt to different scenes, flexibly plan actions, and complete “operations” independently. The robotic arm TRX-Arm is independently developed for human living environments, has seven degrees of freedom and anthropomorphic characteristics, and has the characteristics of dexterous movement, strong explosive power, integrated touch control, and soft and safe.

According to Tencent Robotics X Lab WeChat official account, in terms of movement ability, thanks to the innovative rigid-flexible hybrid drive mechanism design and self-developed high-power density driver, Tencent TRX-Hand has both high dexterity and high load speed. It has 8 independently controllable joints, weighs only 1.16 kg, has a maximum continuous fingertip force of 15 Newtons, and a maximum joint speed of no less than 600 degrees per second. It can easily handle the grasping and operation of objects of different shapes and sizes, and is also good at high-dynamic throwing and catching. At the same time, the flexible-driven fingertip design effectively improves the impact resistance of the fingers.

In terms of perception ability, the dexterous hand is covered with a self-developed high-sensitivity flexible tactile sensor array on the fingertips, finger pulps and palms, and a micro laser radar and proximity sensor are installed in the palm. At the same time, each joint is integrated with an angle sensor to ensure that the dexterous hand can accurately perceive the state information of itself and the object during grasping and operation.

In addition, unlike traditional collaborative robotic arms, TRX-Arm uses a combination of rope transmission and differential drive, which not only effectively reduces transmission friction and motion inertia, but also realizes multi-motor multi-joint collaborative drive, with high dynamic motion capabilities. At the same time, its forearm integrates a 768-point tactile array with a refresh rate of up to 1000Hz, thereby achieving high-frequency real-time positioning of wine bottles during rolling and balancing.

Tencent said that the Robotics X laboratory will continue to promote the integration of its self-developed robot dexterous hand TRX-Hand and robotic arm TRX-Arm, and introduce cutting-edge algorithms such as deep learning to enhance the robot’s dexterous operation ability and ability to solve complex problems, so that it can better serve real needs.
