In the past decade there has been a significant increase in the use of omni-directional video — video that captures information in all directions. The bulk of this research has concentrated on the use of omni-directional video for navigation and for obstacle avoidance. This paper reviews omni-directional research at the VAST lab that address other applications; in particular, we review advances...

This paper proposes a mobile printer system (MPS) based on multi-robot cooperation. The system consists of multiple mobile robots, a wireless LAN system, a graphic user interface (GUI), and a host computer. The GUI comprises a user input section, a task allocation optimization section, and a control and communication section. Its operation is as follows: a user draws a picture on an input windo...

This paper addresses the problem of autonomous mobile ro bot navigation in a simple indoor environment We present a system which combines the paradigm of visual servoing with appearance based methods The only sensory information available to the robot comes from an omni directional vision camera The geometry of our system which uses a spherical mirror is presented Our algorithm relies on a sequ...

We address the problem of indoor mobile robot navigation by center following without prior environmental information based on visual information provided by a single camera. Recently, the research on the mobile robot of the automatic moving type works actively (DeSouza & Kak, 2002). It is an important problem to acquire moving environment information to move automatically. Various sensors such ...

Testing and validation of flight hardware in ground-based facilities can result in significant cost savings and risk reduction. We designed a relative motion emulator for aerospace vehicles using omni-directional mobile bases which provide large 3 degree-offreedom motion, while Stewart platforms mounted atop these bases allow superposition of limited 6 degree-of-freedom motion. This paper addre...

In this paper, dimensioning of Universal Mobile Telecommunication Systems (UMTS) Radio Access Method (RAN) has been performed with respect to varying antenna gain of NodeB and sectorization of site layout of network sites. Three different site layouts have been configured to estimate the number of sites required to cover the deployment area. In the first site layout, Single Omni directional ant...

This paper addresses the issue of development of a three wheel, four wheels and eight wheel Omni directional mobile robot. The Omni directional wheel is used in this research consists of 8 rollers made from synthetic rubber coated polypropylene rollers. All Omni wheel are independently powered using 3, 4 and 8 units of precision gear DC motors and the wheel/ motors assemblies where mounted dire...
