AI Technical Summary
Existing six-degree-of-freedom rotary robotic arms struggle to adapt quickly to complex and ever-changing production environments, requiring frequent reprogramming. They also lack sufficient intelligence, safety, and interactive capabilities, limiting their application in a wider range of industrial sectors.
A six-degree-of-freedom rotating humanoid robotic arm was designed, which uses dual motors to drive the shoulder, elbow and wrist joints to achieve flexible movement in all directions and at multiple angles. It is equipped with different protection levels and quick-release bases, and is equipped with associated software to achieve efficient collaborative operation.
Robotic arms are highly flexible and precise, can adapt to complex working environments, improve production efficiency and safety, reduce operating difficulty and maintenance costs, and enable efficient collaborative work with human workers.
