This paper presents theoretical and experimental results on observer-based impedance control. Impedance control is a technique for robot force control, which is often used to deal with geometric uncertainty. The aim of this technique is to obtain a dynamic relation between position and force in interaction similar to Newton's second law. Here the velocity is used to modify the damping of the imped
In situations where robots are performing manipulation tasks, e.g. welding, grinding, and drilling, it is necessary to avoid excessive forces in the contact with the environment. Because of geometric uncertainty and finite positioning accuracy this usually cannot be solved by position control alone. The subject of this thesis is robot force control, with particular interest devoted to impedance co
Cognitive control is a skill used to control one’s own behaviour to reach a goal. We compared this skill across archosaurs by using the distraction task on American alligators, emus, chickens, and common ravens. We investigated whether the animals would still find a food reward hidden behind one of two identical opaque barriers after picking up a food distraction. Results show that all species can
Injectable Bioresorbable Organic Bioelectronics Neuropharmacology—our ambition is to supplement classical biochemical signaling with the modulation of bioelectricity using both ionic and electronic processes. We focus on organic electronics that self-assemble directly inside or near the nervous system to form electronic circuits that mimic its structure and organization, enabling seamless integratInjectable Bioresorbable Organic Bioelectronics Neuropharmacology—our ambition is to supplement classical biochemical signaling with the modulation of bioelectricity using both ionic and electronic processes.

Achieving asthma control remains an elusive goat for the majority of patients worldwide. Ensuring a correct diagnosis of asthma is the first step in assessing poor symptom control; this requires returning to the basics of history taking and physical examination, in conjunction with lung function measurement when appropriate. A number of factors may contribute to suboptimal asthma control. Concomit
