چکیده
This paper describes the visual control of a parallel robot called “RoboTenis”. The system has been designed and built in order to carry out tasks in three dimensions and dynamical environments; the system is capable to interact with objects which move up to 1m/s. The control strategy is composed by two intertwined control loops: The internal loop is faster and considers the information from the joints, its sample time is 0.5 ms. Second loop represents the visual servoing system, is external to the first mentioned and represents our study purpose, it is based on predicting the object velocity which is obtained form visual information, its sample time is 8.3 ms. Lyapunov stability analysis, system delays and saturation components has been taken into account.

Adaptive Voltage-based Control of Direct-drive Robots Driven by Permanent Magnet Synchronous Motors
Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...

The intelligence of a mobile robot is highly dependent on its vision. The main objective of an intelligent mobile robot is in its ability to the online image processing, object detection, and especially visual tracking which is a complex task in stochastic environments. Tracking algorithms suffer from sequence challenges such as illumination variation, occlusion, and background clutter, so an a...
متن کاملVision-Based Control of the RoboTenis System
In this paper a visual servoing architecture based on a parallel robot for the tracking of faster moving objects with unknown trajectories is proposed. The control strategy is based on the prediction of the future position and velocity of the moving object. The synthesis of the predictive control law is based on the compensation of the delay introduced by the vision system. Demonstrating by exp...
متن کامل3D tracking using two high-speed vision systems
When considering real-world applications of robot control with visual servoing, both 3D information and a high feedback rate are required. We have developed a 3D target tracking system with a 1ms feedback rate using two high-speed vision systems called Column Parallel Vision (CPV) systems. To obtain 3D information, such as position, orientation, and shape parameters of the target object, a feat...

Reliable object tracking at video speed is a task that requires high performance. We have analyzed the various parts of typical algorithms and found that some parts of program flows are best performed on a parallel platform for performance reasons and other parts are better performed on a sequential processor for reliability and versatility reasons. Combining the two processing profiles in one ...

In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
