Vision being the most important human sensor and feedback system is considered to play a prominent role in the future of robotics. Robust techniques for visual robot navigation are essential in service robotics tasks. This contribution presents a novel approach to large view visual servoing of a mobile robot with a pan-tilt camera. A predictive camera(More)
Flexible, lightweight manipulators offer some advantages in contrast to rigid arms, such as compact and lighter drives, energy efficiency, reduced masses and costs. This paper presents a novel approach for vibration damping of a multi-link flexible arm. The strain of the elastic arms is measured with Fiber-Bragg-Grating (FBG) sensors and provides the(More)
This paper presents a novel approach to large view visual servoing in the context of object manipulation. In many scenarios the features extracted in the reference pose are only perceivable across a limited region of the work space. The limited visibility of features necessitates the introduction of additional intermediate reference views of the object and(More)
Mobile manipulation in service robotic applications requires the alignment of the end-effector with recognized objects of unknown pose. Image based visual servoing provides a means of model-free manipulation of objects solely relying on 2D image information. This contribution proposes a visual servoing scheme that utilizes the pixel coordinates, scale and(More)
Robotic manipulation of daily-life objects is an essential requirement in service robotic applications. In that context image based visual servoing is a means to position the end-effector in order to manipulate objects of unknown pose. This contribution proposes a 6 DOF visual servoing scheme that relies on the pixel coordinates, scale and orientation of(More)
