We have previously shown the expression of the extracellular calcium (Ca2+o)-sensing receptor (CaR) in osteoblast-like cell lines, and others have documented its expression in sections of murine, bovine, and rat bone. The existence of the CaR in osteoblasts remains controversial, however, since some studies have failed to document its expression in the same osteoblast-like cell lines. The goals...

Fuzzy set theory, originally developed by Lotfi Zadeh in the 1960’s, has become a popular tool for control applications in recent years (Zadeh, 1965). Fuzzy control has been used extensively in applications such as servomotor and process control. One of its main benefits is that it can incorporate a human being’s expert knowledge about how to control a system, without that a person need to have...

Is it possible to build virtuous robots? And is a good idea? In this paper in machine ethics, I offer positive answer both questions. Although moral architectures based on deontology and utilitarianism have been most often considered, argue that virtue ethics approach may ultimately be more promising program artificial agents (AMA). The basic idea robot should behave as person would (or recomme...

The motion planning problems for non-holonomic car-like robots have been extensively studied in the literature. The curvature-constrained shortest-path problem is to plan a path (from an initial connguration to a nal connguration, where a connguration is deened by a location and an orientation) in the presence of obstacles, such that the path is a shortest among all paths with a prescribed curv...

Joint design and load transmission are crucial factors when building autonomous robots. On the one hand, heavy torques are often needed which result in multi-stage gearboxes, on the other hand the latter exhibit massive friction which gets in the way of energy-efficient actuation systems. Furthermore, the immense impact forces of a tumbling robot can easily break its joints, gears, and motors. ...

A three-level functional architecture for a team of mobile robots is described in detail, including the deenition of the role assigned to each level, the main concepts involved, and the corresponding implementation for each individual robot. The architecture is oriented towards teams of fully autonomous cooperative robots, able to carry out diierent types of cooperative tasks. Complexity is red...

Although groups of robots are expected to interact with groups of humans in the near future, research related to teams of humans and robots still appears scarce. This paper contributes to the study of human-robot teams by investigating how humans choose robots to partner with in a multi-party game context. The novelty of our work concerns the successful design and development of two social robo...
