Development of Robotic Hand Wrist with 1kg Payload

This paper presents a robotic hand wrist with a 1kg payload that has been developed to collect user input via an application and send the required signals to a robotic wrist to move left, right, up, down, grip, and ungrip, where the WebSocket protocol is used to establish wireless communication. The rise of industrial and service robots has sparked renewed interest in robotics research in recent years. Individuals with varying abilities can use assistance with daily activities. This paper introduces a robotic gripper that has features to carry objects such as pens, bottles, boxes, and balls, whose weight ranges from 50g to 800 g, and has gripping accuracy of 73.75% for pens, 80% for mobile phones, 88.5% for boxes, and 86% for bottles. For the protection of items, proper speed control of the motor is initialised using the PID (proportional integral derivative) algorithm at the time of pick and place, and soft cushioning is attached to the robotic hand for a firm grip. The whole process of picking and placing is semiautomated and can be controlled by three buttons. The gripper can be controlled from anywhere as it is based on a wireless communication protocol based on Wi-Fi.
