Recently, autonomous robots have been widely used in the production field. There are several advantages to introducing industrial robots in factories. However, these robots cannot be used in unknown environments because most of them are controlled by sequence controls. Two cameras are used as vision sensors that can recognize the outside environment to solve this problem. In this study, we aim at...
Recent advances in development of low-cost 3D sensors, such as Microsoft Kinect, bring attractive opportunities to robot system integrators. The accuracy provided by such sensors is generally unsatisfactory for many robotic applications, but it may be improved through calibration. This paper presents a calibration case study that is based on the sensor calibration procedure involving only a use of...
This paper introduces the development of a novel autonomous high accuracy 3D shape measurement system. A fringe projection system is mounted at the end effector of an industrial robot to measure the object shape. Through a special geometrical construction and calibration of the fringe projection system the system is feasible to measure at large and also at short distances with a large measurement...
In this paper, we have achieved kinematic calibration of the purely translational Orthopod parallel mechanism via a flexible measuring system, which is based on Costar SI-M350 CCD camera with TEC-M12 lens. We first identify intrinsic parameters of the camera and the camera calibration result is verified using a simple yet practical experiment. Then we perform manipulator calibration using its inverse...
The major goal of research regarding mobile service robotics is to enable a robot to assist human beings in their everyday life. This implies that the robot will have to deal with everyday life environments. One of the most important steps towards able service robots is to enhance the ability to operate well in unstructured living environments. In this paper we focus on the integration of object recognition,...
A key requirement for unmanned aerial vehicles (UAV) applications is the attitude stabilization of the aircraft, which requires the knowledge of its orientation. It is now well established that traditional navigation equipments, like GPS or INS, suffer from several disadvantages. That is why some works have suggested a vision-based approach of the problem. Especially, catadioptric vision is more and...
Binocular active hand-eye visual system on parallel mechanisms is a novel workspace monitoring mechanism, which fixed on the moving platform of a parallel mechanism with a circular orbit. Considering kinematic coupling between the parallel mechanism and the visual system, a general scheme based on the 3D reconstruct model of a binocular stereo vision is proposed to evaluate the control errors of the...
Deep Green is a vision-based, intelligent robotic system that currently shoots pool at a better-than-amateur level, with the ultimate goal of challenging a proficient human opponent at a championship level. The system's robotic aspects rely primarily on computer vision. The system is centered on a 3-degree-of-freedom gantry robot mounted to the ceiling to avoid impeding human access to the table.
