AI Technical Summary
Technical Problem
Existing robotic fingers have difficulty controlling the gripping force when holding soft or fragile items, which can easily cause damage to the items.
Method used
The robot adopts a rigid-flexible coupling mechanical finger structure. By combining a gripping airbag and a support spring, it uses a pressure sensor to monitor the gripping force. Combined with the drive mechanism and gripping mechanism, it achieves flexible gripping and adjusts the gripping force by inflating and deflating the airbag.
Benefits of technology

Abstract
This invention relates to the field of robotics and proposes a rigid-flexible coupling robotic mechanical finger structure, including a fixed plate and two sets of gripping fingers. Each gripping finger comprises a first phalanx, a second phalanx, and a fingertip that rotate sequentially from end to end. The first phalanx is rotatably mounted on the fixed plate. The structure also includes a gripping airbag, a drive mechanism, and a gripping mechanism. The gripping airbag is fixedly mounted on the end of the fingertip, and an air pump is installed inside the fingertip. The gripping airbag is connected to an inflation valve and a deflation valve, which are used to inflate the airbag. Four drive mechanisms are provided, each driving two first phalanxes and two second phalanxes to rotate. The gripping mechanism drives the fingertip to rotate in order to grip objects. This technical solution addresses the problem in existing technologies where the excessive gripping force of mechanical fingers causes damage to some objects.
