AZIMUT is a mobile robotic platform that combines wheels, legs and tracks to move in three-dimensional environments. The robot is symmetrical and is made of four independent leg-track-wheel articulations. It can move with its articulations up, down or straight, or to move sideways without changing the robot's orientation. To validate the concept, the rst prototype developed measures 70.5 cm 70....

Experiences with Spirit and Opportunity, the twin Mars Exploration Rovers, showed that one of the major issues that needs to be addressed in order to expand the exploration capabilities of planetary rovers is that of wheel traction. The relationships governing how much traction a wheel can produce are highly dependent on both the shape of the wheel and terrain properties. These relationships ar...

A self-contained autonomous dead reckoning (DR) system is desired to complement the Global Navigation Satellite System (GNSS) for land vehicles, which odometer-aided inertial navigation (ODO/INS) a classical solution. In this study, we use wheel-mounted MEMS IMU (Wheel-IMU) substitute odometer, and further, investigate three types of measurement models, including velocity measurement, displacem...

Most existing frameworks for electronic negotiations today are tied to specific negotiation systems for which they were developed, preventing them from being applied to other negotiation scenarios. Thus, the evaluation of electronic negotiation systems is difficult as each one is based on a different framework. Additionally, each developer has to design a new framework for any system to be deve...

This paper presents an experimental study of the electronic differential system with four-wheel, dual-rear in wheel motor independently driven an electric vehicle. It is worth bearing in mind that the electronic differential is a new technology used in electric vehicle technology and provides better balancing in curved paths. In addition, it is more lightweight than the mechanical differential ...

Movable Party is a mobile, real-time interactive music system where audience-participants pedal stationary bicycles to generate power and perform interactive music. Inspired by nakashi Taiwanese street performance culture, Movable Party creates a bustling public and streetside vibrancy in the decentralized metropolis of Los Angeles. The system consists of three stationary bicycles, each equippe...

Many vehicle systems contain rolling elements which exhibit unstable rolling motion, called shimmying, which may lead to disastrous results. The classical shimmying wheel is a simple model which captures the essential dynamics of such systems. Fortunately, this model possesses a particular geometric structure which provides a simple means to design a globally stabilizing controller. However, th...

In this paper we propose a palette-style volume visualization interface which aims at providing users with an intuitive volume exploration tool. Our system is inspired by the widely used wheel-style color palette. The system initially creates a set of direct volume rendered images (DVRIs) manually or automatically, and arranges them over a circle in 2D image space. Based on the initial set of D...

The seed-metering device of the no-tillage planter was driven by the ground wheel. Sliding was unavoidable when the ground was covered by the straw. High sliding brought seeding absence and affected the quality of sowing. In order to monitor the sliding of the ground wheel, a monitoring system composed of hardware and software was designed based on ATMEGA16 Microcomputer. In the system, the pra...
