Robot arm capable of micro-manipulation

Robot arm with disk-link wire bending and interchangeable grippers for micro-manipulation

This technology is a robot arm control system designed for obstacle avoidance and micro-manipulation, featuring a flexible link section where multiple disks are connected by link wires, and a gripper opening/closing mechanism driven by wire tension.

Conventional rigid-link robot arms have limited workspaces, struggle to avoid obstacles in confined areas, and are restricted in their ability to grasp objects of various sizes due to the use of integrated grippers.

This technology features a design where disks with opposing convex surfaces are connected by link wires to allow for bending, a sliding groove within the gripper for detachable connection to the link section, and variable control of the gripper opening width through wire tension adjustment.

Key Features:

• A link section configured to be bendable, with at least one or more disks connected by link wires
• A gripper section including a gripper drive unit provided at one end of the link section to handle targets and adjust the width of the opening
• A control unit that manages the link wires to rotate the disks, thereby controlling the bending of the entire link section
• A gripper with a sliding groove that receives a sliding protrusion from the link section, allowing for replacement with different grippers
