This book establishes recursive relations concerning kinematics and dynamics of constrained robotic systems. It uses matrix modeling to determine the connectivity conditions on the relative velocities and accelerations in order to compare two efficient energetic ways in dynamics modeling: the principle of virtual work, and the formalism of Lagrange's equations. First, a brief fundamental theory is presented on matrix mechanics of the rigid body, which is then developed in the following five chapters treating matrix kinematics of the rigid body, matrix kinematics of the composed motion, kinetics of the rigid body, dynamics of the rigid body, and analytical mechanics. By using a set of successive mobile frames, the geometrical properties and the kinematics of the vector system of velocities and accelerations for each element of the robot are analysed. The dynamics problem is solved in two energetic ways: using an approach based on the principle of virtual work and applying the formalism of Lagrange's equations of the second kind. These are shown to be useful for real-time control of the robot's evolution. Then the recursive matrix method is applied to the kinematics and dynamics analysis of five distinct case studies: planar parallel manipulators, spatial parallel robots, planetary gear trains, mobile wheeled robots and, finally, two-module hybrid parallel robots.

This book investigates the utilization of harmonics in the permanent magnet (PM) or rotor shape to improve the torque density of PM brushless AC machines including three-phase inner rotor and outer rotor machines, five-phase machines, dual three-phase machines, linear machines, by means of analytical, finite element analyses, and as well as experimental validation. The torque density can be improved while the torque ripple remains low in PM shaping utilizing the 3rd harmonic. In this book, the analytical expression of output torque is derived for PM machines with rotor shape using the 3rd harmonic, and then the optimal 3rd harmonic for maximizing torque is analytically obtained. The book compares the PM shape in surface-mounted PM (SPM) machines and the rotor lamination shape in interior PM (IPM) machines utilizing the 3rd harmonic, and it becomes clear that their shaping methods and amount of torque improvement are different. In a five-phase PM machine, the 3rd harmonic can be utilized in both the current waveform and PM shapes to further improve the output torque. For the dual three-phase SPM machines without deteriorating the torque more than 30% when the optimal 3rd harmonic into both the current and PM shape are injected. The harmonics in airgap flux density have significant influence on the cogging torque, stator iron flux distribution, and radial force between the rotor and stator. These effects has been investigated as well in this book.

This book discusses the core principles and practical applications of a brand new machine category: liquid-metal soft machines and motors. After a brief introduction on the conventional soft robot and its allied materials, it presents the new conceptual liquid-metal machine, which revolutionizes existing rigid robots, both large and small. It outlines the typical features of the soft liquid-metal materials and describes the various transformation capabilities, mergence of separate metal droplets, self-rotation and planar locomotion of liquid-metal objects under external or internal mechanism. Further, it introduces a series of unusual phenomena discovered while developing the shape changeable smart soft machine and interprets the related mechanisms regarding the effects of the shape, size, voltage, orientation and geometries of the external fields to control the liquid-metal transformers. Moreover, the book illustrates typical strategies to construct a group of different advanced functional liquid-metal soft machines, since such machines or robots are hard to fabricate using rigid-metal or conventional materials. With highly significant fundamental and practical findings, this book is intended for researchers interested in establishing a general method for making future smart soft machine and accompanying robots.

Excerpt: ... APPENDIX (B). Abstract of Evidence and Reports made by a Select Com? mittee of the House of Commons, on Steam Engines and Furnaces. MICHAEL ANGELO TAYLOR, ESQ, In the Chair. Mr. Joseph Gregson, Surveyor, called in and examined. Was of opinion that the nuisance that arose from the smoke of steam engine furnaces might be attributed to two causes: one, the putting on the fire or furnace too much crude fuel at one time; the other, from the chimnies being commonly too low, in proportion to the fuel consumed.--Had seen this nuisance effectually removed; but it had generally been attended with an increased consumption of fuel: it was seldom adopted but where the parties had been or were under an indictment.--His own invention consisted in, causing all the smoke after it had arisen from the fire, to return into the heat of the fire before it entered into the flue or chimney, and so was consumed; 2dly, By putting on no more fuel at any one time than the smoke of which can be so consumed, and that without opening the furnace door for the purpose; 3dly, By supplying every fire with air, in order to counteract the effect of those winds that operate against the draft.--Had employed it in the fires and boilers of private houses, under steam engine boilers, and in wealding furnaces, where a number of bits and scraps of iron were packed together, and subjected to an intense heat 3 they were, in that state, then rolled or hammered into one compact body.--The result however in the latter case was, that although every thing acted according to the plans laid down, and the fire was regularly supplied with fuel, and the smoke completely destroyed, yet the heat necessary to weald those scraps of iron together could never be attained, and this was in consequence of the continued...

Stationary steam engines were the quiet powerhouses of the Industrial Revolution. They provided the driving force behind every manufacturing process for well over a century, as well as drainage of mines and allowing clean water supplies for the majority of our towns and cities. From a small sewage pump at the edge of a field of a few horsepower, to a 12,000 horsepower leviathan rolling armoured plate for battleships, these wonders of the steam age kept working for many decades, unseen by many, but often loved by the men who operated and maintained them. The engine houses they were kept in could be plain or ornate, and a rich variety of boilers provided the steam for them. This book looks at all of these aspects and what it was like to run a large steam engine for industry. The legacy of these iron giants is seen in the dozens of engines preserved for posterity all over the UK, in museums or in their original locations, giving thousands of people the chance to see them or enjoy getting involved in their preservation. This book is part of the Britain's Heritage series, which provides definitive introductions to the riches of Britain's past, and is the perfect way to get acquainted with stationary steam engines in all their variety.

Sir James Alfred Ewing (1855-1935) was a Scottish engineer, physicist and cryptographer. First published in 1926, as the fourth edition of an 1894 original, this book was written by Ewing 'to present the subject of heat-engines, in their mechanical as well as their thermodynamical aspects, with sufficient fulness for the ordinary needs of University students of engineering'. The text was extensively revised for this edition, taking into account developments in relation to steam turbines, steam boilers and internal combustion engines. Numerous illustrative figures are also provided. This book will be of value to anyone with an interest in Ewing's writings, steam engines and the history of engineering.

Following distinguished service during the Napoleonic Wars, the Scottish naval officer and Arctic explorer Sir John Ross (1777 1856) embarked on an abortive expedition to discover the North-West Passage. The existence of the Croker mountains, which he claimed had blocked his path, was afterwards disputed and his reputation suffered. His 1819 account of that voyage has been reissued in the Cambridge Library Collection. Prior to setting out in a steam vessel on a second expedition, for which he would be knighted, Ross published the present work in 1828. Seeking to establish himself as an authority on steam power when the technology was still in its infancy, Ross explores the development of the steam engine, the commercial and military potential of steam navigation, and how this called for a radical change in naval tactics. Illustrated throughout, this is the work of a practical maritime mind, combining both historical and technical detail.
