Abstract

The loss of functionality or total absence of an upper limb is an issue that affects millions of individuals, impacting their daily lives and performance in professional activities. Despite advances in prosthetic technology over time, problems regarding applicability in real-life scenarios and adaptability to differing circumstances have plagued variants of modern prosthetics. The objective of BioSync is to alleviate these troubles by equipping the disabled with a bionic prosthetic that senses and adjusts movements in real-time under the glenohumeral joint. The methods involved in the efficacy of BioSync include a proportional-integral-derivative (PID) control system that provides precise and stable joint actuation, a reverse kinematics model that allows for natural mobility, and a machine learning fault-detection mechanism that ensures proper operation. The system uses electromyography (EMG) signals, long short-term memory networks, and a Neuro-Fuzzy model that detects anomalies but also ensures optimal adaptability. 𝒖(𝒕) = 𝑲 𝒑 𝒆(𝒕) + 𝑲 π’Š ∫ 𝒆(𝝉)𝒅𝝉 𝒕 𝟎 + 𝑲 𝒅 𝒅𝒆/𝒅𝒕 The above equation shows the PID equation utilized in the control system. A statistical analysis conducted on the prosthetic's performance in assisting the completion of everyday tasks demonstrated the functionality of the device. The fault detection framework accurately identified deviations from standard operating patterns, the PID loop stably interpreted EMG signals, and the Neuro-Fuzzy model ensured peak system health. In conclusion, the results illustrate the possibility of developing an intelligent prosthetic that can aid in a variety of disabilities in the upper arm by utilizing machine learning to ensure constant workability and safety. The significance of this work highlights the potential for more personalized and user-oriented prostheses that act intuitively to improve the quality of life of many individuals.
