WordPress Shortcode. Published in: Dynamics is the study of the motion of individual bodies and mechanisms under the influence of forces and torques. The study of forces and torques in stationary systems and systems with negligible inertial effects is called statics.
Synthesis is a procedure by which a product a mechanism, for example is developed to satisfy a set of performance requirements. If a product configuration is tentatively specified and then examined to determine whether the performance requirements are met, the process is called analysis.
The design of mechanisms involves both synthesis and analysis. The design process begins with the recognition of a need. A set of requirements is then listed. Creativity and inventiveness are key to selecting the connectivity and form of a mechanism or machine to satisfy the need.
The designer may use formal synthesis procedures in which specifications and corresponding decision sets and design variables must be identified. The designer then prepares an adequacy assessment procedure, formulating a figure of merit and an optimization strategy. Detailed analyses of displacements, velocities, and accelerations are usually required.
This part of the design process is followed by an analysis of forces and torques.
The design process may continue long after the first models have been produced and may include redesigns of components that affect velocities, accelerations, forces, and torques. To compete successfully from year to year, most manufacturers must continuously modify their products and their methods of production.
Increases in the production rate, upgrading of product performance, redesign for cost and weight reduction, and motion analysis of new product lines are frequently required.
Success may hinge on the accuracy of the kinematic and dynamic analysis. These decisions may be verified and modified through analytical, graphical, numerical, and empirical methods. If a linkage is to be analyzed in only one position, graphical vector methods may provide the quickest solution. Complex-number methods are convenient for analyzing planar linkages.
Analytical vector methods are used for solving planar and spatial linkages.
While a calculator is adequate for solving a linkage problem for a single position, it is worthwhile to write a computer program when a solution is required over a range of values. Computer solutions are also effective for analysis and synthesis when it is necessary to evaluate several alternatives.
New and more powerful versions of software appear as well. Motion simulation software e. The linkages can be animated to verify design criteria and compute velocities, accelerations, and forces.
Clearly labeled plots showing the position, velocity, and acceleration of linkages help the designer gain an insight into the motion of a mechanism and give clues leading to an improved design. Mathematics software e.
In this form, equations are readable and easier to debug. Equations embedded in typical programming languages are somewhat less readable. In spreadsheets, equations are usually hidden, but tabular data are clearly displayed.
Solutions by Chapter
An important spreadsheet feature is that when one cell is changed, all related cells are updated to reflect the change. Mathematics software that includes equation solvers, numerical differentiation routines, and routines to manipulate complex numbers, vectors, and matrices can be a significant time-saver in working with mechanisms.
Linkage solutions require direct and inverse trigonometric functions. These "ANAT robots" can be designed with "n" DOF as each module is a complete motorized robotic system that folds relatively to the modules connected before and after it in its chain, and therefore a single module allows one degree of freedom.
The more modules that are connected to one another, the more degrees of freedom it will have. L-shaped modules can also be designed in a chain, and must become increasingly smaller as the size of the chain increases, as payloads attached to the end of the chain place a greater strain on modules that are further from the base. ANAT H-shaped modules do not suffer from this problem, as their design allows a modular robot to distribute pressure and impacts evenly amongst other attached modules, and therefore payload-carrying capacity does not decrease as the length of the arm increases.
Modular robots can be manually or self-reconfigured to form a different robot, that may perform different applications.
Because modular robots of the same architecture type are composed of modules that compose different modular robots, a snake-arm robot can combine with another to form a dual or quadra-arm robot, or can split into several mobile robots, and mobile robots can split into multiple smaller ones, or combine with others into a larger or different one.
This allows a single modular robot the ability to be fully specialized in a single task, as well as the capacity to be specialized to perform multiple different tasks. Modular robotic technology is currently being applied in hybrid transportation,  industrial automation,  duct cleaning  and handling.
Many research centres and universities have also studied this technology, and have developed prototypes. Collaborative robots A collaborative robot or cobot is a robot that can safely and effectively interact with human workers while performing simple industrial tasks.

However, end-effectors and other environmental conditions may create hazards, and as such risk assessments should be done before using any industrial motion-control application.
Intended for sale to small businesses, they are promoted as the robotic analogue of the personal computer. Autonomy and ethical questions Main articles: Roboethics and Ethics of artificial intelligence An android , or robot designed to resemble a human, can appear comforting to some people and disturbing to others  As robots have become more advanced and sophisticated, experts and academics have increasingly explored the questions of what ethics might govern robots' behavior,  and whether robots might be able to claim any kind of social, cultural, ethical or legal rights.
He calls this " the Singularity ". In , experts attended a conference hosted by the Association for the Advancement of Artificial Intelligence AAAI to discuss whether computers and robots might be able to acquire any autonomy, and how much these abilities might pose a threat or hazard. They noted that some robots have acquired various forms of semi-autonomy, including being able to find power sources on their own and being able to independently choose targets to attack with weapons.
They also noted that some computer viruses can evade elimination and have achieved "cockroach intelligence. Researchers at the Rensselaer Polytechnic Institute AI and Reasoning Lab in New York conducted an experiment where a robot became aware of itself, and corrected its answer to a question once it had realised this. However, other experts question this. He believes this represents an important and dangerous trend in which humans are handing over important decisions to machines.
At present the company uses ten thousand robots but will increase them to a million robots over a three-year period. Delaney said "Robots are taking human jobs. The World Bank 's World Development Report puts forth evidence showing that while automation displaces workers, technological innovation creates more new industries and jobs on balance.
Robots can be classified by their specificity of purpose. A robot might be designed to perform one particular task extremely well, or a range of tasks less well. All robots by their nature can be re-programmed to behave differently, but some are limited by their physical form. For example, a factory robot arm can perform jobs such as cutting, welding, gluing, or acting as a fairground ride, while a pick-and-place robot can only populate printed circuit boards.Now available again in this revised edition, the book is a detailed, practical guide and reference to gear technology.
Chapter 11 Important topics include two- and three-position synthesis, design of a function generator, and coupler curves. Mechanisms and Machines. VIII, - p. You can also find solutions immediately by searching the millions of fully answered study questions in our archive. In this form, equations are readable and easier to debug. It's easier to figure out tough problems faster using Chegg Study.
