The handling of complex machines such as redundant manipulators requires appropriate control systems in order to make the operating of the system easier and to reduce processing time. This paper presents an advanced control system for a drilling rig used in tunnel construction which is currently under development in cooperation with an industrial partner. The drill rig is equipped with two redu...

objective: to investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic parkinson’s disease (pd). materials and methods: in this cross-sectional study, 55 patients with idiopathic pd by mean age of 59.85 ± 11.89 years, and mean hoehn and yahr stage ...

In this paper modelling and analysis of the SRM torque characteristics including torque ripples are described. Optimal control strategy based on genetic algorithm (GA) to minimize torque ripple is proposed. The optimization criteria depend on choosing the exact current profile based on the optimal excitation parameters which govern the torque shape. The model and control are carried out on high...

the main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. hence, a field was selected in astaneh-ashrafiyeh and divided to three different plots. two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. according to test results, the lowe...

BACKGROUND AND STUDY AIMS Capsular endoscopy holds promise for the improved inspection of the gastrointestinal tract. However, this technique is limited by a lack of controlled capsule locomotion. Magnetic steering has been proposed by the main worldwide suppliers of commercial capsular endoscopes and by several research groups. The present study evaluates and discusses how robotics may improve...
