This chapter investigates the problem of an aerial manipulator interacting with the environment. The chapter is split into two parts. The former considers an aerial device with tilting propellers that, thanks to a super-twisting slide mode controller, can control the interaction force for inspection task purposes. The latter proposes a hardware-in-...

Semi-autonomous telerobotic systems allow both humans and robots to exploit their strengths while enabling personalized execution of a remote task. For soft robots with kinematic structures dissimilar to those of human operators, it is unknown how the allocation of control between the human and the robot changes the performance. This work presents...

This article proposes a model predictive non-sliding manipulation (MPNSM) control approach to safely transport an object on a tray-like end-effector of a robotic manipulator. For the considered non-prehensile transportation task to succeed, both non-sliding manipulation and the robotic system constraints must always be satisfied. To tackle this pro...

This work proposes an operational space control framework for non-prehensile object transportation using a robot arm. The control actions for the manipulator are computed by solving a quadratic programming problem considering the object's and manipulator's kinematic and dynamic constraints. Given the desired transportation trajectory, the proposed...

This document revises the latest results related to robotic non-prehensile object transportation. The problem consists of a robotic arm transporting an object along the desired trajectory on a tray, guaranteeing a sticking behaviour and other constraints. The solution in [1], where an optimal control problem has been devised, is revised together wi...

Tip steering by induced deformation constitutes one of the most prominent feature to effectively navigate constrained environments with soft growing robots.

This paper addresses the problem of transporting a rigid box filled with unknown objects with a dual-arm robotic system. Enforcing non-sliding contact behavior, which guarantees the transportation of the box despite the unknown load's action, is the main difficulty in this setting. To solve this problem, we propose a high-level model-predictive con...

This paper tackles the problem of nonprehensile object transportation through a legged manipulator. A whole-body control architecture is devised to prevent sliding of the object placed on the tray at the manipulator's end-effector and retain the legged robot balance during walking. The controller solves a quadratic optimization problem to realize t...

Sharing the control of a robotic system with an autonomous controller allows a human to reduce his/her cognitive and physical workload during the execution of a task. In recent years, the development of inference and learning techniques has widened the spectrum of applications of shared control (SC) approaches, leading to robotic systems that are c...

Semi-autonomous telerobotic systems allow both humans and robots to exploit their strengths, while enabling personalized execution of a task. However, for new soft robots with degrees of freedom dissimilar to those of human operators, it is unknown how the control of a task should be divided between the human and robot. This work presents a set of...

The most effective expression of the 4.0 Era is represented by cyber-physical systems (CPSs). Historically, measurement and monitoring systems (MMSs) have been an essential part of CPSs; however, by introducing the 4.0 enabling technologies into MMSs, a MMS can evolve into a cyber-physical measurement system (CPMS). Starting from this consideration...

This article proposes a shared-control teleoperation architecture for robot manipulators transporting an object on a tray. Differently from many existing studies about remotely operated robots with firm grasping capabilities, we consider the case in which, in principle, the object can break its contact with the robot end-effector. The proposed shar...

Although substantial progresses have been made in robot-assisted laparoscopic surgery, the graspers for existing surgical systems generally remain non-sensorized forceps design with limited functions.

In this paper, an intelligent variable impedance control combined with a fuzzy gain dynamic surface is proposed to improve the interaction of the robot manipulator with an unknown varied environment. The parameters of the proposed variable impedance are adapted by optimization an introduced cost function using a recurrent fuzzy wavelet network. The...

Executing multiple tasks concurrently is important in many robotic applications. Moreover, the prioritization of tasks is essential in applications where safety-critical tasks need to precede application-related objectives, in order to protect both the robot from its surroundings and vice versa. Furthermore, the possibility of switching the priorit...

During suturing tasks performed with minimally invasive surgical robots, configuration singularities and joint limits often force surgeons to interrupt the task and re-grasp the needle using dual-arm movements. This yields an increased operator's cognitive load, time-to-completion and performance degradation. In this paper, we propose a haptic-guid...

Research activity in Minimally Invasive Robotic Surgery (MIRS) has gained a considerable momentum in the last years, due to the availability of reliable and clinically relevant research platforms like the da Vinci Research Kit (dVRK). However, despite the wide sharing of the dVRK in the research community, access to the platform remains limited bec...

Robot teleoperation is widely used for several hazardous applications. To increase teleoperator capabilities shared-control methods can be employed. In this paper, we present a passive task-prioritized shared-control method for remote telemanipulation of redundant robots. The proposed method fuses the task-prioritized control architecture with hapt...

Introduction and Objectives Fabrication processes for spinal orthoses require accurate three-dimensional (3D) models of the patients' trunk.

We propose a novel haptic guidance method for a telerobotic manipulation system, which is able to deal with several different system's constraints, such as collisions, joint limits, and singularities. In addition, we combine the haptic guidance with a shared-control algorithm for autonomous orientation control meant to further simplify the executio...

In laparoscopic Minimally Invasive Robotic Surgery a teleoperated robot is interposed between the patient and the surgeon. Despite the robot aid, the manipulation capabilities of surgical instruments are far from those of the human hand. In this work we want to make a step forward towards robotic solutions that can improve the manipulation capabili...

During robot-aided surgical interventions, the surgeon can benefit from the application of virtual fixtures (VF). Though very effective, this technique is very often not practicable in unstructured surgical environments. In order to comply with the environmental deformation, both the VFs geometry and the constraint enforcement parameters need to be...
