A wirelessly controlled medical robotic hand locally

Abstract

We focused on one of the many uses of robotic systems in our study. In particular, we wanted to enter the medical field to implement a hand-controlled wirelessly through a glove. The main function of this hand is to replicate the movements of the hand of the user wearing the control glove. In order for the robotic hand to react to incoming signals effectively and efficiently, it records these natural hand movements as a basis for information. The control glove consists of multiple parts: An Arduino microcontroller is used to process data from the sensors on the glove. Five adaptable and bendable sensors detect movement from the fingers and thumb. A special unit is used to measure acceleration and motion to determine wrist rotation. Wireless communication between the glove and the robotic hand is made possible thanks to the nRF24L01 transmitter. Six servo motors – one for each finger and wrist – are embedded in the robotic hand, which was created using a 3D printer. The design was obtained from the open source 3D CAD library. The robotic hand contains an Arduino microcontroller and nRF24L01 receiver module. When the design is complete, he will be able to replicate the movements of the control glove without any noticeable delay and demonstrate his ability to grasp different objects. We collected hand-building supplies and electronic circuits from the local market. The results indicate that the ability of the robotic hand to grip hard surfaces can be improved by providing additional degrees of freedom to the fingers. Sensitivity was tested and we found that each of the glove's sensors was approximately linear and with varying accuracy. This arm could be an innovative solution for people with mobility impairments, such as those with upper limb paralysis or individuals who struggle to lift objects effectively. Those who work remotely for safety reasons or who work in hazardous environments may find this technology very useful.
