Lane change manoeuvres are known to vary widely in lane change duration. This is thought to be an effect of the surrounding vehicles and personal preference of drivers. However, little is known about the effect on steering behaviour during a lane change manoeuvre. Moreover, the relation of the effect of traffic to inter- and intra-driver...

An issue in driving simulation is that behaviour displayed in simulation does not exactly replicate behaviour in real-life. For example, roadside vegetation density impacts a driver’s speed and lateral position in on-road studies, but not in driving simulator studies. In this study it is investigated if the increase in fidelity and presence that...

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...

In recent years, rapid progress has been made towards automated highway driving. To increase comfort and trust in these automated cars, their motion planners, such as Model Predictive Controllers (MPCs), should exhibit a human-like driving style. However the effect of surrounding traffic on overtaking maneuvers has not yet been investigated....

Semi-autonomous robotic exoskeletons enable paraplegics to walk again. The exoskeleton envelops the paraplegic’s waist, legs and feet. When the user gives the command to start walking, the exoskeleton’s robotic legs start a cyclic walking motion. The user, aided by crutches, follows this fixed cyclic motion, shifting their weight to the stance...

The technological advancements in the automotive industry have enabled the automation of numerous routine driving tasks. As a result, the art of driving has become a control task with a strong supervisory character, including the common human factor issues. Haptic Shared Control has been shown to be useful in keeping the driver in-the-loop by...

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...

In our aging society, the demand for care is increasing. Therefore, it is foreseen that robots will assist elderly. However, human assistance will often be required by the robot, which thus should be at a position advantageous for telemanipulation. For autonomous manipulation, methods have been developed that position a robot. But for...

Drivers continuously adapt to the different needs and constraints in the driving scene. Literature has provided evidence for two adaptation strategies in response to an increased risk (decreasing the road width or increasing the driving speed) while lane keeping: decreasing driving speed and increasing endpoint arm stiffness. However, so far...

Epiretinal Membrane Peeling (EMP) is a common vitreoretinal surgery in clinic. Over the past twenty years, telerobotics has been developed to assist retinal surgeons. Robot-assisted surgery can aid the surgeon by motion scaling and filtering out natural hand tremor. However, the additive precision has yet to relieve the surgeon from the...

Crew of small fast ships often experience exces- sive vertical accelerations when sailing in waves, leading to discomfort and injuries. In an attempt to avoid this, in good visibility experienced operators reduce speed voluntarily when they anticipate that the next vertical peak acceleration will be unacceptably large. However, at night and...

Context: To investigate the effectiveness of nonlinear calculation of the near and far angle for driver modelling in curve negotiation, simulated data is analyzed based of Mars driver model and the nonlinear realization of Mars model given in Scholtens. Aims: It is shown that due to the dynamic calculation of the near and far angle, the...

—Enabling haptic interaction with non-solid materials, such as liquids or sediments, could expand possibilities for exploration of virtual or remote environments, which would e.g enable training divers and astronauts in simulators. To allow application of natural investigation procedures in such scenarios, haptic interfaces with several degrees...

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...

Lateral acceleration is a key aspect of the vehicle response perceived by the driver. Assistance systems such as Active Rear Steering (ARS) or Torque Vectoring (TV) are developed to modify the lateral acceleration response such that the vehicle has an improved stability and an extended linear handling region. With this extended linear handling...

Driving with Haptic Shared Control (HSC) provides an alternative for traditional traded control in human-controller interaction. Whilst driving, control is shared between the driver and the controller by translating the controller's desired steering input to additional torques on the steering wheel.<br/>Literature provides several guidelines for...

Haptic shared control (HSC) is a method to combine the abilities of humans and machines, in which human and automation jointly exert forces on an input device. According to human-centered design, the underlying controller for HSC should closely resemble human behavior. This paper aims to continuously adapt HSC based on an online identified...

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...

The Rubber Hand Illusion is an illusion in which<br/>visual cues of stimulation on a fake hand are combined with<br/>synchronous tactile cues on a participant’s hand, which can<br/>induce a sense of bodily ownership of the fake hand. This<br/>technique does not facilitate synchronous movement of the<br/>hands, and asynchronous stimulation or...

Haptic shared control enables continuous interaction between driver and automatic controller by means of torques on the steering wheel that guide towards a reference trajectory. Current haptic shared control systems induce conflicts when the reference trajectory of the automation differs from the drivers own desired trajectory, which can lead to...
