Electric-motored personal mobility devices (PMDs) are appearing on Australian roads. While legal to import and own, their use is typically illegal for adult riders within the road transport system. However, these devices could provide an answer to traffic congestion by getting people out of cars for short trips (“first-and-last mile” travel). City of Ryde council, Macquarie University, and Tran...

The fact of the pattern agricultural land conversion in Jambi Province, changes area food crops are more influenced by economic factors (commodity prices, share subsectors) and population growth with a tendency to decline every year. Province is also as result use cultivated from crop plantation cropland massive expansion oil palm plantations. objectives this study are: Evaluating implementatio...

Design, syntheses, and testing of new, fullerene-wheeled single molecular nanomachines, namely, nanocars and nanotrucks, are presented. These nanovehicles are composed of three basic components that include spherical fullerene wheels, freely rotating alkynyl axles, and a molecular chassis. The use of spherical wheels based on C60 and freely rotating axles based on alkynes permits directed nanos...

Tractor–trailer systems have been widely used to increase load transportation capacity. Control of these systems started from motion aid facilities in human-driven vehicles to fully autonomous mobile robots in recent years. In fact, tractor– trailer wheeled robot has been proposed as a modular robotic system in which an actuated mobile robot tows a passive trailer. This is a highly nonlinear un...

In order to develop a mechanical simulation experiment, a dynamic simulation of crawler excavator walking mechanism is designed. The performance of walking mechanism of excavator is tested by dynamic simulation. According to the data analysis, it is known that crawler walking mechanism is an important part of mine excavator and a walking device with better adaptability than wheeled walking mech...

3D DYNAMIC MODELING OF A SPHERICAL WHEELED SELF-BALANCING MOBILE ROBOT Ali Nail İNAL M.S. in Electrical and Electronics Engineering Supervisor: Prof. Dr. Ömer MORGÜL August 2012 In recent years, dynamically stable platforms that move on spherical wheels, also known as BallBots, gained popularity in the robotics literature as an alternative locomotion method to statically stable wheeled mobile r...

As the level of human interaction with robotic systems increases, robot mobility becomes more important. Two wheeled robots offer higher levels of mobility and manoeuvrability when compared to their four wheeled counterparts with the ability to turn on the spot and easily negotiate tight corners. Whilst the stabilisation of two wheeled platforms has been well studied, there is no published rese...

This is a survey on recent joint work with A.R. Gover on the geometry of non–degenerate CR manifolds of hypersurface type. Specifically we discuss the relation between standard tractors on one side and the canonical Cartan connection, the construction of the Fefferman space and the ambient metric construction on the other side. To put these results into perspective, some parts of the general th...
