We analyse video sequences of a hand interacting with a ball. The hand motion is segmented using a piecewise polynomial motion model inspired by research in motor control. Next, an adaptive gravitational model of the ball is used to locate hand-ball events. We show that hand-ball events can be automatically classified from velocity and acceleration profiles.
Integrating machine vision and motion control method into a double layers alignment system is a popular issue in flat panel display and semiconductor industry. An ultra-low stage is considered to compensate the postur...

This paper presents a study of the behavior of piezoelectric micro robot to three degrees of freedom (longitudinal movement. transversal movement and rotation) foreseen to work on flat surfaces. Its main merits are its ability to perform micro-scale displacements and to support heavy pre-loads. An adequate interface is developed, allowing the control of the system. Even, a phase sensitive vision method is developed to sense the position and the heading angle with an accuracy better than 0.2 pixel i.e. 12 mum with an observed field of about 4 x 3 cm(2). A personnel computer controls the whole system.
In this work the tracking control problem is solved using the approximated nonlinear predictive control and it is combined with artificial potential field for obstacles avoidance capabilities. The potential field appr...

In this paper, two global measures of image similarity are compared for use in topological localization of mobile robots. A catadioptric vision system was used as the sensor. Our localization system employs a discrete Bayes filter. Experimental results with real images of an office environment indicate the robot can localize itself from the memorized training images even with the modification of the environment.
robots are becoming more and more prevalent in many real world scenarios. Housekeeping, medical aid, human assistance are a few common implementations of robots. Military and Security are also major areas where roboti...
