Problem statement: Literature review was mainly aiming at recognition of objects by the computer and to make explicit the information that is implicit in the attributes of 3D objects and their relative positioning in the 3D Environment (3DE) as seen in the 2D images. However quantitative estimate of position of objects in the 3DE in terms of their x, y and z co-ordinates was not touched upon. T...

Efficient coverage of an area by a mobile vehicle is a common challenge in many applications. Examples include automatic lawn mowers and vacuum cleaning robots. In this paper a vehicle with uncertain heading is studied. Five control strategies based on position measurements available only when the vehicle intersects the boundary of the area are compared. It is shown that the performance depends...

Over the past five years, the topic of the origins of language is gaining prominence as one of the big unresolved questions of cognitive science. Artificial Intelligence can make a major contribution to this problem by working out precise, testable models using grounded robotic agents which interact with a real world environment and communicate among themselves or with humans about this environ...

Autonomous robotic systems are increasingly being used in a wide range of applications such as precision agriculture, medicine, and the military. These systems have common features which often includes an action by an "actuator" interacting with a target. While simulations and measurements exist for the success rate of hitting targets by some systems, there is a dearth of analytic models which ...

Controllers for autonomous robotic systems can be specified using state machines. However, these are typically developed in an ad hoc manner without formal semantics, which makes it difficult to analyse the controller. Simulations are often used during the development, but a rigorous connection between the designed controller and the implementation is often overlooked. This paper presents a sta...

The recent report by Goethert, Shani, and Telford has demonstrated that strains of Francisella tularensis subsp. tularensis (type A) on the island of Martha’s Vineyard are of multiple genotypes (3). In that paper, the authors stated that the mode of transmission of the two outbreaks (summer 1978 and summer 2000) of pneumonic tularemia (1, 5) from this island remain “undescribed” (3). I propose ...

Biological organisms perceive and act in the world based on spatiotemporal experiences and interpretations. However, artificial agents consider mainly the spatial relationships that exist in the world, typically ignoring its temporal aspects. In an attempt to direct research interest towards the fundamental issue of time experiencing, the current work explores two temporally different versions ...

Thing is a robotic hand with three digits, a pronating opposable thumb, and a 2 D.O.F. wrist. Designed to more accurately model human hand positioning and grasping capabilities than previous models, Thing is controlled by a flex-sensor-equipped glove which relays the user’s finger positions by means of flex sensors. It will also, by time of publication, incorporate an image-processing system fo...

Topology is an important area of study in mathematics, which is mainly concerned with qualitative properties of objects or spaces. It is broad and well developed. Current research interests are to explore the possibilities to integrate topological perspectives in various practical engineering problems. Robotics contains many challenging tasks and provides an ideal playground for topological too...

Auburn University has a competition Autonomous Lawnmower team and competes every year at ION’s competition [1] in Dayton, OH. This paper describes the how the team has approached coverage path planning for the lawnmower given the competition constraints. The competition setting dictates a closed polygon filed, which can be concave, and it will contain several static and dynamic obstacles. The p...
