Abstract
This article is the second of a two-part tutorial on visual servo control. In this tutorial, we have only considered velocity controllers. It is convenient for most of classical robot arms. However, the dynamics of the robot must of course be taken into account for high speed task, or when we deal with mobile nonholonomic or underactuated robots. As for the sensor, geometrical features coming from a classical perspective camera is considered. Features related to the image motion or coming from other vision sensors necessitate to revisit the modeling issues to select adequate visual features. Finally, fusing visual features with data coming from other sensors at the level of the control scheme will allow to address new research topics

Model-Less Feedback Control of Continuum Manipulators in Constrained Environments

TL;DR: This work uses an optimal control strategy on a tendon-driven robot to demonstrate model-less control, which allows the manipulator to interact with several constrained environments in a stable manner and is the first work in controlling continuum manipulators without using a model.

Feature Depth Observation for Image-based Visual Servoing: Theory and Experiments

TL;DR: This work proposes a visual servoing approach where depth is observed and made available for servoing by interpreting depth as an unmeasurable state with known dynamics, and building a non-linear observer that asymptotically recovers the actual value of Z for the selected feature.

A new technique for fully autonomous and efficient 3D robotics hand/eye calibration

TL;DR: In this article, the authors describe a technique for computing position and orientation of a camera relative to the last joint of a robot manipulator in an eye-on-hand configuration, which takes only about 100+64N arithmetic operations to compute the hand/eye relationship after the robot finishes the movement, and incurs only additional 64 arithmetic operations for each additional station.
