Özet

The goal of this research is to create a novel and costeffective robotic finger gripper. Textiles, food items, and even fragile electronics require specialized handling abilities to guarantee they are grabbed securely and without causing damage. A controlled gripper equipped with force sensors and feedback can keep objects from deforming when grabbing. Furthermore, the creation of a flexible and soft surface with material bumps enhances friction, which may prevent the object from slipping. This design can provide an ideal environment for item grabbing and manipulation, analogous to the human fingerprint. This paper describes the use of an optical force sensor with a soft and flexible sensing surface for a highprecision actuated gripper. A force sensor can provide feedback to a control loop to activate a picking mechanism. The sensing surface is intended to provide friction, preventing the clutched object from dropping. This research focuses on the planned molding, optical sensor features, and circuit concept using the photodiode array. In addition, a study on sensor reflectometry and simulation of gripper mechanisms is given and tested. MATLAB and Simscape are used to control a servomotor that controls the gripper. Remarkable results demonstrate how to use the provided design concepts for control activities with haptics.
