This letter proposes a control framework for dual-arm robotic manipulation of a common workpiece, with the objective of tracking a reference trajectory for the object while minimizing the internal stress on it using pose/force controllers. The visual-tactile observations provided by the individual r
Robotic manipulation of objects in cluttered dynamic scenes is challenging for a twofold reason. Object detection and localization are complex due to partial occlusions and high variability in the object classes and manipulation in tight spaces is difficult due to potential collisions. The present l…

Visual control based on image features has received much attention for its inherent robustness against camera calibration errors, modelling uncertainties and the capability to keep the object in the Field of View (FoV) of the camera. Nevertheless, some drawbacks related to the basin of convergence a
The main purpose of this letter is to demonstrate that smart exploitation of force/tactile feedback can enable successful physical cooperation of two robot manipulators to handle a common object with a high degree of dexterity. The novelty of the letter is that dexterity is provided not only by the
A robust grasp controller for both slipping avoidance and controlled sliding is proposed based on force/tactile feedback only. The model-based algorithm exploits a modified LuGre friction model to consider rotational frictional sliding motions. The modification relies on the Limit Surface concept wh…
Manipulation planning and control are relevant building blocks of a robotic system and their tight integration is a key factor to improve robot autonomy and allows robots to perform manipulation tasks of increasing complexity, such as those needed in the in-store logistics domain.

Parallel jaw grippers have a limited dexterity, however they can still be used for in-hand manipulation tasks, such as pivoting or other controlled sliding motions of the grasped object. A rotational sliding maneuver is challenging since the grasped object can easily slip if the grip force is not pr…
