AI Technical Summary

Technical Problem

Existing robotic arm grippers for cleaning often fail to grasp glass cleaning baskets accurately, resulting in either missing the target or grasping only one side while missing the other.

Method used

The structure includes a first drive assembly and a second drive assembly. The first drive assembly consists of a first motor and a first transmission structure, and the second drive assembly consists of a second motor and a second transmission structure. The first motor drives the first transmission structure, and the second motor drives the second transmission structure, thereby driving the first and second robotic arms to achieve mechanical transmission and improve the grasping accuracy.

Benefits of technology

The starting accuracy of the robotic arm's gripper device has been improved, reducing the occurrence of missed grasps and ensuring accurate gripping.
