Planning and visual-servoing for robotic manipulators in ROS

Dynamic Position-Based Visual Servoing of Robotic Manipulators

− This paper discusses dynamic visual servoing and proposes a position-based approach to visual servo control of robotic manipulators. Several dynamic visual servoing control architectures used for position-based are addressed in this paper, in order to motivate the proposed approach. In position-based visual servoing, the features used to control the robot manipulator, actual pose of the objec...

Visual Servoing for Robotic Assembly

Visual feedback has traditionally been used in the assembly process to a very limited extent. With the advent of effective visual servoing techniques, visual feedback can become an integral part of the assembly process by complementing the use of force feedback to accomplish precision assemblies in imprecisely calibrated robotic assembly workcells. In this paper we present some of the issues pe...

Robust 2.5D Visual Servoing for Robot Manipulators

In this paper, the 3-dimensional (3D) position and orientation of a camera held by the end-effector of a robot manipulator is regulated to a constant desired position and orientation despite (i) the lack of depth information of the actual or desired camera position from a target, (ii) the lack of a geometric model of the target object, and (iii) uncertainty regarding both the angle and axis of ...

A visual servoing controller for robot manipulators

Abstract— This paper presents a new control family of fixedcamera visual servoing for planar robot manipulators. The methodology is based-on energy shaping methodology in order to derive regulators for position-image visual servoing. The control laws have been composed by the gradient of an artificial potential energy plus a nonlinear velocity feedback. For a static target we characterize the g...
