Design and Kinematic Modeling of Wrist-inspired Joints for Restricted Operating Spaces

Strategic Insights -

Research on designing wrist-inspired joints has made significant progress in enabling flexibility and maneuverability in robotic manipulators and grippers for restricted operating spaces. A team of researchers from Nankai University in Tianjin, China, has developed a wrist-inspired joint with an integrated drive system, allowing for simultaneous pitch and yaw movements. This innovative design combines the flexibility of soft joints with the high rigidity of discrete joints.

The researchers, led by Ning Sun, have applied this technology in manipulators and grippers, demonstrating its potential in various applications. Experimental results have verified the effectiveness of the wrist-inspired joints in achieving flexibility and maneuverability. The study's findings suggest that this technology can be useful in fields such as search and rescue, disaster response, and healthcare.
