Falling remains a large source of (traumatic) injuries and healthcare costs. Over the past years, different actuators have been developed in the field of wearable robotics to help prevent injuries from falling. To increase the wearability of these systems, the weight of power storage can be decreased with intermittent instead of continuous...

In this work, we propose a method of processing patient input on discomfort level during robot shoulder physiotherapy into discomfort maps. These maps represent the patient's discomfort distribution throughout the range of motion of the shoulder, interpretable by both physiotherapists and robots. This method consists of three parts: the patient...

Robotic interventions have become a pivotal component in minimally invasive neurosurgical procedures. While the use of robotic devices in medical operations is advancing, there is still a pressing need to train and equip medical professionals with emerging biomedical developments. Though Virtual reality (VR) has been proven to be a great tool...

Robots can aid in post-stroke motor function recovery and motor learning through the use of haptic feedback during collaborative training. A clear objective in robotic-assisted motor learning is to adapt the haptic feedback to individual users, but personal characteristics are not yet considered in this adaptation. <br/><br/>We investigated the...

Introduction: Although robotic-assisted surgery is increasingly performed, objective assessment of technical skills is lacking. The aim of this study is to provide validity evidence for objective assessment of technical skills for robotic-assisted surgery. Methods: An international multicenter study was conducted with participants from the...

Introduction: Robot-assisted surgery is often performed by experienced laparoscopic surgeons. However, this technique requires a different set of technical skills and surgeons are expected to alternate between these approaches. The aim of this study is to investigate the crossover effects when switching between laparoscopic and robot-assisted...

The complexity of handheld steerable laparoscopic instruments (SLI) may impair the learning curve compared to conventional instruments when first utilized. This study aimed to provide the current state of interest in the use of SLI, the current use of these in daily practice and the type of training which is conducted before using SLI in the...

BACKGROUND: Current robot-aided training allows for high-intensity training but might hamper the transfer of learned skills to real daily tasks. Many of these tasks, e.g., carrying a cup of coffee, require manipulating objects with complex dynamics. Thus, the absence of somatosensory information regarding the interaction with virtual objects...

In the past two decades, robotic systems have been introduced to assist surgeons in improving the control of surgical instruments. To fully and safely utilize the potential of robotic precision, relative displacement and vibrations between the robotic system and the human tissue should be minimized. This study presents the design of an interface...

The use of robots has attracted researchers to design numerous haptic training methods to support motor learning. However, investigations of new methods yielded inconclusive results regarding their effectiveness to enhance learning due to the diversity of tasks, haptic designs, participants skill level, and study protocols. In this review, we...

Despite recent advances in robot-assisted training, the benefits of haptic guidance on motor (re)learning are still limited. While haptic guidance may increase task performance during training, it may also decrease participants' effort and interfere with the perception of the environment dynamics, hindering somatosensory information crucial...

Robotic assistance for rehabilitation has benefited from the use of models for motor adaptation. The assist-as-needed paradigm for rehabilitation robotics was based on a single-state model of human adaptation to a neurological handicap. Recent studies have shown that human motor adaptation consists of two or more parallel adaptation processes. A...

As part of the ongoing research on balance assistance at the Delft Biorobotics Lab, the goal of this project was to analyse the relevance of optimising the control action to each individual user. In order to explore the feasibility of tuning balance assistance based on task performance as well as controller assistance, an experimental study was...

For assistive exoskeletons, researchers have introduced soft exoskeletons (exosuits) because they tend to be lightweight, easily worn and mobile for daily use. However, most existing devices have not introduced closed-loop control methods that users can intuitively learn and use during activities of daily living. The goal of this pilot study is...

This paper introduces a novel control framework for an arm exoskeleton that takes into account force of the human arm. In contrast to the conventional exoskeleton controllers where the assistance is provided without considering the human arm biomechanical force manipulability properties, we propose a control approach based on the arm muscular...

In this thesis, manual welding with robot assistance is studied. A variable impedance control scheme is developed to suppress the undesired movements of unskilled welders. The impedance parameters of damping and mass are investigated. Mass increases the undesired movements and is disregarded. Damping decreases the undesired movements, helping to...
