In this paper, we focus on the “Vuton-II”, a new omni-directional vehicle developed as a transport vehicle to operate within factories, hospitals, and warehouses. This vehicle is composed of three or more “Omni-Discs.” The Omni-Disc mechanism ensures that individual wheels of the Omni-Disc assembly are always aligned in the same direction, and can always roll freely. The Vuton-II was based on t...

This article has focused on evaluation and identification of effective parameters in positioning performance with an odometry approach of an omni-directional mobile robot. Although there has been research in this field, but in this paper, a new approach has been proposed for mobile robot in positioning performance. With respect to experimental investigations of different parameters in omni-dire...

This paper describes an efficient method to obtain 3D information from omni images using EPI analysis. Two types of omni cameras are employed to make a spatio-temporal volume, which is a sequence of omni images stacked in the spatio-temporal space. For the EPI analysis of omni image, we examine different types of cross sections in such spatiotemporal volumes. To conduct the EPI analysis realist...

This paper presents experimental analysis of wheeled mobile robots. Mathematical modelling of the mobile robot is presented. The mobile robots consist of an omni-directional and three differential drive mobile robots are tested and moved in given trajectories and the systematic errors of the robots are determined. A new method for omni-direction mobile robot was introduced in which the robot wa...

UNLABELLED This study examined reliability and concurrent validity of the newly developed OMNI-vibration exercise scale (OMNI-VIBRO) to measure Ratings of Perceived Exertion (RPE) during vibration exercise in twenty recreationally active students (12 males and 8 females). The criterion variables were muscle activity of the Vastus Medialis (VM), Vastus Lateralis (VL), Biceps Femoris (BF), and Me...

OBJECTIVE To determine smoking behaviour, acceptability, and toxin exposure when smokers switch to the potential reduced exposure product-Omni cigarette. DESIGN 12 week randomised, crossover study of Omni versus own cigarettes. PARTICIPANTS 19 light/ultralight and 15 regular smokers. OUTCOMES Cigarettes/day, smoking topography, craving, withdrawal symptoms, urinary cotinine plus its glucu...

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...

PURPOSE The stepping pictorial format of the Children's OMNI Perceived Exertion Scale (0-10) was validated for female (N = 20) and male (N = 20) children, 8-12 yr old with a peak (step) oxygen consumption of 46.1 +/- 5.3 mL.kg(-1).min(-1). METHODS Ratings of perceived exertion for the overall body (RPE-O), legs (RPE-L), and chest (RPE-C) were determined by the OMNI-Step Scale. Concurrent scal...

Due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. However, omni directional navigation system, omni-vision system and kicking mechanism in such mobile robots have not ever been combined. This situation brings the idea of a robot with no head direction into existence, a comprehensive omni directional mobile robot. Such...

Omni-drive systems operate by having individual wheels apply torque in one direction in the same way as a regular wheel, but are able to slide freely in another direction (often perpendicular to the torque vector). The key advantage of omni-drive systems is that translational and rotational motion are decoupled for simple motion. However, in considering the fastest possible motion this is not n...
