Robotic Metal Inert Gas (MIG) and Tungsten Inert Gas (TIG) welding are the most widely used automated welding process in manufacturing industry. A novel robotic welding monitoring system is proposed and developed to detect inconsistencies during the welding process. The welding monitoring system assesses the weld quality and provides a real-time feedback to the welding robot. A new on-line analysis...
In the marine & offshore industry, the repair of buoyancy modules involves removal of defective regions which is commonly conducted manually using hand-held abrasive tools. This manual process is one of the key bottlenecks of the production process and the removed material can be hazardous to operators' health. To lower manpower costs, and together improve efficiency while minimizing the disruption...
Robotic Metal Insert Gas (MIG) and Tungsten Insert Gas (TIG) welding are responses for growing need from industry for welding process automation. With the well-established process knowledge, a weld monitoring system is developed in this study for manual or robotic TIG/MIG welding to allow the detection of process inconsistency and to assess the welding quality in real-time. A new method of welding...
This paper presents a new wearable lower extremities assistive robotic device that aims at providing assistive torque for stroke patients during rehabilitation process. The device specifically provides the assistive torque by detecting the user's intention using surface electromyography (EMG) signals with the force/torque estimation method based on continuous wavelet transform (CWT). The general hardware...
This paper describes the development of hardware and software of Human-Machine Interface (HMI) for active assistive device based on surface Electromyography signals (sEMG). The sEMG signals have been chosen as the most intuitive and transparent source of information on detection of users intention. For work presented in this paper, our research activities focus mainly on development of hardware, algorithms...
