Developing a high-performance patient-to-image registration system for robotic cochlear implant surgery: Through the human-robot interaction-focused design method leading to a multi-modal, multi-feedback admittance control, touch-based pair-point bone-anchored fiducial registration and its performance measured in accuracy, workload, usability and trust

This thesis presents the research to design a successful high-accuracy, sub-millimetric registration method for an autonomous robot equipped to drill bone for cochlear implant (CI) surgery. Its performance, and thus success, is measured in accuracy, workload, usability and trust. While state-of-the-art (STOTA) research lacks the inclusion of...

Wind load simulations and inertia scaling using an industrial robot arm

Existing wind load simulators such as wind tunnels and fans have multiple disadvantages, especially when used in a scaled-down environment. This paper proposes to simulate wind loads by using an admittance-controlled industrial robot arm rigidly attached to a research object. Admittance control should make it possible to simulate wind loads and...

Evaluation of Force Controllers for a Gravity-Compensating Upper Limb Soft Exoskeleton

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...
