“Are you a mechatronics fan and are looking for a simple Arduino project to do? Well, here is a simple yet very important mechanism used in many robots nowadays. Robots are designed to satisfy a certain need or to make life easier in a certain way. The gripping action is actually a common task performed by many robots to fulfill their assigned mission. In this instructable, you will learn how to make a three-fingered electronic gripper automated with pushbuttons.
