告别机器人“手残”！中国团队研发六自由度机械臂 GL-Robot ，能捏鸡蛋还能举哑铃！

Core Viewpoint - The article highlights the innovative capabilities of the GL-Robot, a dual-finger robotic arm developed by Zhejiang University, which combines strong gripping power with delicate touch sensitivity, overcoming traditional limitations in robotic grasping technology [3][20]. Group 1: Technical Innovations - GL-Robot features a unique design with each finger having three joints, providing a larger contact area for stable and secure gripping, similar to human hand functionality [4][6]. - The internal "stacked four-bar mechanism" allows the fingers to intelligently switch between two grasping modes based on the object being handled, enhancing adaptability [8]. - The robot employs a "sensor-free" force perception method by analyzing the current signals from the driving motor, which correlates with the load and external environment, thus eliminating the need for expensive sensors [9][10]. Group 2: Grasping Modes and Performance - GL-Robot operates in two distinct modes: a precision operation mode for delicate items like eggs, achieving force control as low as 0.1 N, and a heavy-duty mode for larger objects, capable of handling loads up to 350 N [13][17]. - The robot's design allows it to grasp a wide range of objects, from thin coins to large cubes, demonstrating superior stability and adaptability in various scenarios [19]. Group 3: Commercial Potential - The absence of costly force sensors in GL-Robot not only enhances its performance but also significantly reduces production costs, indicating strong commercial viability in industrial and logistics applications [19][20].
