In this paper concentrated on the design of a minimum rule based fuzzy-logic controller for robot navigation, and hurdles avoidance in cluttered environment, based on the Mamdani type fuzzy method. The controller has 3 inputs, and single output. This technique generates suitable heading angle maneuvers control of the autonomous vehicle which is used by the robot to reach its goal safely without...

Lower-extremity injury is common in soccer. A number of studies have begun to assess why specific lower-extremity injuries occur. However, currently few studies have examined how footwear affects lower-extremity mechanics. In order to address this question, 14 male (age: 22.1 ± 3.9 years, height: 1.77 ± 0.06 m, and mass: 73.3 ± 11.5 kg) and 14 female (age: 22.8 ± 3.1 years, height: 1.68 ± 0.07 ...

With the advancements in micro-electromechanical systems (MEMS) technologies, magnetic and inertial sensors are becoming more and more accurate, lightweight, smaller in size as well as low-cost, which in turn boosts their applications in human movement analysis. However, challenges still exist in the field of sensor orientation estimation, where magnetic disturbance represents one of the obstac...

Monocopter is a single-wing rotary flying vehicle which has the capability of hovering. This flying vehicle includes two dynamic parts in which more efficiency can be expected rather than other Micro UAVs due to the extended area of wing compared to its fuselage. Low cost and simple mechanism in comparison to other vehicles such as helicopter are the most important specifications of this flying...

Abstract The velocity obstacle method has extensive research in collision avoidance, which uses circles to represent robots or ships find a collision-free velocity. To better describe the motion characteristics of ships, an improved based on elliptical ship domain is proposed this paper. In previous domains own and target are seldom considered at same time. This paper considers time judges whet...

Abstract. Pedestrian dead reckoning (PDR) can solve the position information by its inertial measurement unit (IMU), which is a method to achieve indoor autonomous positioning without deploying base stations in advance. However, affected accumulated error, accuracy will decrease with increase of moving distance. To improve accuracy, step length estimation PDR improved. A combining on walking fr...
