Design, implementation and performance analysis of a microcontroller based wireless electromyography device

Improper design of manual materials handling (MMH) tasks at workplace can cause musculoskeletal disorders such as muscle strain to industrial workers. To avoid these disorders, ergonomists and engineers require an integrated measurement system which allows them to study the interaction of body posture and muscle effort during performing MMH tasks. However, far too little attention has been paid to develop an integrated measurement system of body posture and muscle activity for assessing MMH tasks. The aim of this study was to develop and test a prototype of integrated system for measuring postural angles and electromyography (EMG) signals of a worker who doing MMH tasks. The Microsoft Visual Studio software, a 3D camera (Microsoft Kinect), Advancer Technologies muscle sensors and a microcontroller (NI DAQ USB-6000) were applied to develop the integrated postural angle and EMG signal measurement system. Additionally, a graphical user interface was created in the system to enable users to perform body posture and muscle effort assessment simultaneously. Based on the testing results, this study concluded that the patterns of EMG signals are depending on the postural angles which consistent with the findings of established works. Further study is required to enhance the validity, reliability and usability of the prototype so that it may facilitate ergonomists and engineers to assess work posture and muscle activity during MMH task.

Lojik devre laboratuvarı Elektrik-Elektronik Mühendisliği bölümü için önemli laboratuvarlardan bir tanesidir. Entegreler deneyler sırasında doğru bir şekilde çalışmalıdır. Entegre devrelerin düzgün çalışıp çalışmadığını test etmek için bir devre kurmak zor ve zaman alıcıdır. Bu çalışmada, entegre test cihazı entegre devrelerin hızlı ve doğru bir şekilde test edilmesi için tasarlanmıştır. Entegre test cihazında, Microchip tarafından üretilen PIC18F452 mikrodenetleyicisi kontrol ve test algoritmalarının gerçeklenmesi için kullanılmıştır. PIC18F452 düşük güç tüketimine, yüksek performansa ve geliştirilmiş FLASH/EEPROM teknolojisine sahiptir. Entegre test cihazını kullanmak kolay ve basittir. Entegreleri zif-sokete takmak yeterlidir. Test devresi, entegrelerin düzgün çalışıp çalışmadığını LCD ekranda göstermektedir. Entegre test cihazının prototipi üretilerek Lojik devre laboratuvarında kullanılmıştır. Laboratuvar personelinin deneme ve yorumları, entegre test devresinin laboratuvarlarda güvenle kullanılabileceğini göstermektedir.

Exoskeletal robots are used as high-tech products in the military, health and industrial applications. The integration of robots and humans offers new opportunities for the creation of new assistive technologies that can be used in biomedical, industrial and military applications. This paper presents the mechanical design, modeling and simulation of 2 degrees of freedom (DOF) upper limb exoskeletal robot. The system can be used both for supporting load lifting and for rehabilitation of upper limbs. A load cell was used to measure the applied load. Encoders were used to measure the shoulder and elbow joint angles. An electromyograph was developed to measure muscular activation. In this study, simulation was conducted with the PID position control, however the system hardware is applicable for a force control architecture.
