Teleoperated semi-autonomous care robots aim to alleviate work pressure from care workers. Unlike many traditional stiff position-controlled robots, the care robot is operating in a shared environment with humans that is often unpredictable and unknown. Especially when dealing with tasks that involve contact with the environment, modulation of...

Haptic assistance (HA) has been shown to be useful in a wide variety of applications by providing the benefits of automation while keeping the human in the loop. In recent years, providing additional visual feedback has been found to provide benefits to HA interfaces by complementing their advantages and mitigating their weaknesses. However, the...

The progress in technology has made vehicles safer and the quest to make them even more safe is never ending. Autonomous cars present the solution to make cars much more safer by eliminating the primary cause of road accidents, human error. However, autonomous cars tend to fail in decision making especially in complex traffic environment...

Teleoperation of a robot is often necessary when the remote site is not safe for humans. Moreover, to interact with dynamic environments safely, a teleoperation method called teleimpedance, which allows the human operator to control the impedance of the robot, is used. The main drawback of this method is that the human workload may increase....

Joint limits and singularities limit the total and intuitive utilization of the robotic workspace in VR mediated teleoperation. This paper presents the development and validation of a novel null-space projection control method, used to adjust joint configurations of teleoperated robot arms containing joint limits and singularities. The novel...

Automation in a domestic environment is not flawless and human interference will be necessary, for implementing robots in this environment. <br/>When remotely controlling semi-autonomous robots, proposed concepts can be divided into two main concepts: To trade control back and forth between the human and the operator and to share control...

Haptic Shared Control (HSC) can improve operator performance during teleoperation. HSC uses assistive forces on the master device to guide the operator's control input towards a reference trajectory. However, the reference trajectory might be incorrect due to inaccuracies in the sensed or modeled environment and thus not match the intended...

Teleoperation allow us to manipulate environments that cannot be manipulated directly by a human operator, like space and deep sea, but they are also used in surgery to scale movements and filter out unwanted movements. Commercial teleoperators often lack haptic feedback to the user. Literature shows that a lack of haptic feedback can reduce...

Teleoperation allows the use of human intelligence and decision making in remote tasks which are too dangerous for humans to perform. Technologies such as force feedback and haptic guidance have shown to increase task efficiency during teleoperation. In an unmodeled environment, sensors provide input for haptic guidance or present extra...

A telemanipulation system lets a human operator manipulate an environment on distance, using a master and a slave device, which are connected by a bilateral controller that controls the master and the slave device and provides the communication between these devices. The master device is manipulated by the operator and these actions are...

When tasks need to be performed in remote, potentially inaccessible and/or hostile environments for humans, it is often more convenient to send a robot. Such environments are often only partially known, and therefore not suitable for fully autonomous robots to operate in. In these situations teleoperation can be used, which combines the problem...

Teleoperation is widely used in human-hostile or otherwise inaccessible environments. However, using teleoperation to perform a task is more difficult than performing the task directly. A main factor for this is limited telepresence due to the absence or distortion of natural sensory feedback. An interesting possibility to increase telepresence...

A common method to obtain workspace extension of the slave's workspace is through rate control because it has an unlimited workspace of the slave. However, when contact interaction with the remote environment is needed, position control is often proposed due to the force feedback. To benefit from the strengths of both of these control types,...

Unmanned Aerial Vehicle (UAV) teleoperators suffer from a reduced situational awareness, contributing to a high UAV accident rate. The implementation of a haptic interface is a way to provide them with more information about obstacles in the environment in order to compensate for this. Research focused on systems that actively help the...

Deep sea mining is currently being investigated as a possibility to harvest valuable materials from mineral-rich areas located in water depths up to 2000 meters. One promising mining method is to employ a large crawler on the seabed, remotely controlled by an operator on the supporting vessel. Controlling such a vehicle is expected to be...

This research investigates a neuromuscular analysis based tuning algorithm for haptic cues that has been hypothesized to simultaneously improve safety and workload when compared to heuristic tuning, applied to a haptic collision avoidance system for unmanned aircraft teleoperation. This novel tuning method considers the combined stiffness of the...

To improve teleoperated task performance and control effort, haptic shared control can assist the human operator along a safe and optimal path with continuous guiding forces from an automated controller. But previous research tested such shared control on tasks that were accurately defined in the controller (giving flawless guiding forces),...

This thesis reports on the development of an efficient grasp master for space robotics teleoperation that will complement the haptic human arm master X-Arm-2 (Schiele 2011). It should provide the hand and fingers of various operators with sensing and feedback functions, enabling bilateral teleoperation of various types of robotic end-effectors...

In teleoperations, haptic feedback allows the human operator to touch the remote environment. Yet it is only partially understood to what extent the quality of haptic feedback contributes to human-in-the-loop task performance. This paper presents a human factors experiment in which telemanipulated task performance is assessed for three stages of...

This thesis presents a remote vision system designed to be used for telepresence applications. Telepresence is essentially being able to assert one's presence at a remote location. Being able to see and talk to people in another corner of the world is one method of telepresence we have come to know as video conferencing. As technologies evolve,...
