AI Technical Summary

Technical Problem

Insufficient link stiffness or unreliable joint connections in existing robotic arms lead to decreased motion accuracy and collision interference between robotic arm components, causing damage.

Method used

The lever arm assembly adopts a structural design including a reinforcing member, a drive plate, and a driven plate. The drive plate and the driven plate are connected by the reinforcing member to form a three-dimensional structure, which increases rigidity and strength. The drive assembly is connected to the output shaft through transmission, avoiding a suspended structure and improving connection reliability.

Benefits of technology

It improves the rigidity and load capacity of the robotic arm, reduces deformation and vibration, enhances connection reliability, and prevents the robotic arm from going out of control and being damaged.
