چکیده

In this paper we present an algorithm to compute set-point (i.e. a position to be reached by the robot) automatically from conic features virtually placed by an operator onto the object. We then use a visual servoing algorithm to guide the gripper to its final position. We have tested this algorithm in trying to open a valve with a 6 degree of freedom robot arm, using only visual information and without any model of the valve.

Automated Tracking and Grasping of a Moving Object with a Robotic Hand-Eye System

Most robotic grasping tasks assume a stationary or fixed object. In this paper, we explore the requirements for tracking and grasping a moving object. The focus of our work is to achieve a high level of interaction between a real-time vision system capable of tracking moving objects in 3-D and a robot arm with gripper that can be used to pick up a moving object. There is an interest in explorin...

Biologically Motivated Hand-Eye Coordination for the Autonomous Graspin of Unknown Objects

In the eld of visually guided grasping, humans still outshine their robotic counterparts with respect to accuracy, speed, robustness, and exibility. We therefore examined current neuroscientiic models for the control of human reach-to-grasp movements and, based on one of them, developed a novel visual motion control strategy. This control strategy was integrated into a complete hand-eye system,...

Pose Estimation for Grasping Preparation from Stereo Ellipses

This paper describes an approach for real-time preparation of grasping tasks, based on the low-order moments of the target’s shape on a stereo pair of images acquired by an active vision head. The objective is to estimate the 3D position and orientation of an object and of the robotic hand, by using computationally fast and independent software components. These measurements are then used for t...

Book Detection and Grasping in Library Scenario

Total or shared autonomous behavior is still an open challenge for service robots. An example of such system is FRIEND (Functional robot arm with user-friendly interface for Disabled people) (Figure 1). In the project ReIntegraRob care robot FRIEND will carry out all necessary manipulations for a completely paralyzed person who with support of FRIEND will be able to work in library. The task of...
