This paper presents trajectory tracking and heading adjustment systems of a Mecanum wheel robot using fuzzy logic controller (FLC) and inertia measurement unit (IMU) sensor. It is known that when a Mecanum wheel robot moves, its wheels may slip due to various floor conditions. During such a slip condition, the exact position and orientation of the robot often deviate from that which was intended....
In this paper, we propose a robotic wheelchair control architecture for reactive navigations to improve safety. The proposed solution is developed based on the XScale embedded platform and real-time embedded Linux. A touch panel is used to display useful information for users. In addition, reactive navigation techniques of mobile robots are developed by combining the obstacle detection sensor information...
Robotic cleaners are market-proven service robots. The most challenging issue of producing a robotic cleaner is to maximize its coverage performance. The complete coverage performance depends on the obstacle detection sensors as well as on the navigation systems. Conventional contact, infrared, and ultrasonic sensors perform either collision-based or collision-free perceptions with obstacles, and...
This paper describes an electrooculography (EOG) based human-wheelchair interface for wheelchair users. A pair of electrodes which measures the eye-gaze direction of users is desired as wheelchair manipulation commands. In addition to EOG based wheelchair manipulations, this paper also introduces ultrasonic arrays for detecting distances to actively avoid collisions. In order to simplify setup procedures...
Powered wheelchairs are popular mobility aids for most disabled patients and elders. Most of powered wheelchairs are manipulated via a conventional joystick. The powered wheelchair user has to control the direction and velocity of a powered wheelchair in a very narrow joystick operation range. Therefore, the user's joystick command may be very sensitive to the wheelchair motions. In addition, such...
