Suction grippers have the advantage to handle many different types and sizes of items, without being restricted by the dimensions of clamps to enclose an object and to handle objects more delicately. <br/>However, the challenge of attaching these grippers to irregularly-shaped and rough surfaces remains a persistent issue. Despite advancements...

Haptic Shared Control (HSC) systems offer a means to naturally support human drivers in the transition to automated driving. Tuning of HSC requires knowledge of the neuromuscular system (NMS) of drivers. This MSc thesis project aimed to experimentally validate a linear parameter varying (LPV) technique for modeling driver neuromuscular...

Summary<br/> <br/>This project is carried out in collaboration with bicycle accessories manufacturer Widek BV. Widek came with the plan to create a new design for bicycle handlebar grips with an increased ergonomic value compared to the currently available alternatives. The origination of this plan lies with the release of a paper containing new...

Tactile sensing provides crucial information about the stability of a grasped object by a robotic gripper. Tactile feedback can be used to predict slip, allowing for timely response to perturbations and to avoid dropping objects. Tactile sensors, included in robotic grippers, measure vibrations, strain or shearing forces which are produced by...

This research explores the possibility of upscaling bio-inspired designed soft robots in transport engineering application with the focus on grabbing and manipulating break bulk such as windmill blades or rolls of steel. Upscaling current state soft robotic systems includes challenges regarding the structural strength of the robot. Also...

This thesis contains the design process of a compliant shape adaptive chicory gripper for robotic sorting processes. The robotic sorting line consists of an input and output conveyor-belt. The input line contains unsorted chicories which are scanned by a robotic vision system. Overhead FlexPicker robots, equipped with chicory grippers, sort the...

Drainage of fluid from wet adhesive-substrate interfaces is often mentioned to be an important mechanism in obtaining strong grip. It has been hypothesized that micropatterned adhesives – that contain features (e.g., pillars) separated by channels on their surface – have a better drainage capability compared to unpatterned adhesives....

For the application of composite materials to become more widespread and replace traditional materials their manufacturing processes and final products will need to be competitive and be e.g. lighter, stronger or stiffer and quicker, easier or more cost-efficient to produce than traditional materials. The state of the art for pick-and-place...

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...

Lifting an object by capillary forces is mostly done with a single liquid bridge which connects the target object to a probe. In this work the potential of capillary forces for soft-tissue manipulation is investigated; not only a single liquid bridge is used, but multiple bridges as well since capillary forces can be enhanced by contact...

An important design choice for Haptic Shared Control is the magnitude of assisting forces: high assisting forces are beneficial during agreement between operator and controller, but also result in larger conflict forces in case of disagreement. In order to use higher forces without increasing conflict forces, literature proposes Adaptable Haptic...

Myoelectric as well as body-powered hand prostheses, the two commercially available prosthetic control types, have both their specific advantages. Advanced myoelectric prostheses for example have the characteristic of facilitating multiple degrees of freedom due to grip type variation and/or wrist movements. Compared to prosthetic devices with...

Development of adaptive haptic shared control system requires understanding of the adaptive nature of the driver’s neuromuscular system. In this study, linear parameter varying modeling techniques are proposed to identify changes in the admittance of the driver’s arm. The admittance describes the relation between the torque applied to the...

Robots that are developed for applications which require a high stiffness-over-inertia ratio, such as pick-and-place robots, machining robots, or haptic devices, are often based on parallel manipulators. Parallel manipulators connect an end-effector to an inertial base using multiple serial kinematic chains. This architecture enables the design...

Background: Little is known about action-perception learning processes underlying prosthetic skills in body-powered prosthesis users. Body-powered prostheses are controlled through a harness connected by a cable that might provide for limited proprioceptive feedback. This study aims to test transfer of training basic tasks to functional tasks...

Traditional Electronic Stability Control (ESC) systems influence planar vehicle motions to better match these to the driver’s intention. These systems use the Anti-lock Braking System (ABS) hardware to generate the needed tire forces. This has a large impact on longitudinal vehicle motions. A second method of altering the front wheel tire forces...

Orthopaedic surgery includes frequent removal of bony tissue with large instruments that require a significant force to operate. An increasing number of surgeons, especially female and older surgeons, cannot operate high-load orthopedic instruments properly because they lack the necessary force or hand span. The goal of this study is to develop...
