Visual Servoing for Floppy Robots Using LWPR
We have combined inverse kinematics learned by LWPR with visual servoing to correct for inaccuracies in a low cost robotic arm. By low cost we mean weak inaccurate servos and no available joint-feedback. We show that from the trained LWPR model the Jacobian can be estimated. The Jacobian maps wanted changes in position to corresponding changes in control signals. Estimating the Jacobian for the...
متن کاملImage Based Visual Servoing: Estimated Image Jacobian by Using Fundamental Matrix VS Analytic Jacobian
This paper describes a comparative study of performance between the estimated image Jacobian that come from taking into account the geometry epipolar of a system of two cameras, and the well known analytic image Jacobian that is utilized for most applications in visual servoing. Image Based Visual Servoing architecture is used for controlling a 3 d.o.f. articular system using two cameras in eye...
متن کاملHybrid Position and Image Based Visual Servoing for mobile robots
Visual servoing requires the target object to be in the field of view of the camera all the time. At the same time, we also want to achieve optimal path planning and controllability of the robot pose. This paper presents a new hybrid fuzzy control method for visual servoing of mobile robots to meet these requirements. IBVS (Image Based Visual Servoing) calculates the motion plan directly from t...
متن کاملVisual servoing using dynamic image parameters
Visual servoing is a framework for achieving the tight coupling of camera movements and information from images. We consider a typical visual servoing approach that uses geometric information about image features for controlling the position and attitude of a camera. We extend the applicability of this approach by using image motion information. To this end, we present two diierent approaches t...
متن کاملVisual servoing of mobile robots using non-central catadioptric cameras
This paper presents novel contributions on image-based control of a mobile robot using a general catadioptric camera model. A catadioptric camera is usually made up by a combination of a conventional camera and a curved mirror resulting on an omnidirectional sensor capable of providing 360o panoramic views of a scene. Modeling such cameras has been subject of significant research interest in th...
