Understanding what, when and where to use the wide variety of reliability engineering tools available helps in achieving the highest reliability in products, processes and services. This paper outlines the value of using Weibull Analysis, Reliability Block Diagrams Reliability Centered Maintenance and Root Cause Analysis and as techniques for processes, products, equipment and services improvement. Reliability Engineering tools help to determine the relationship between the process and the equipment. A demonstration of where and how the reliability engineering techniques can be applied is shown in the research. Every product and process design and their development are unique such that meticulous planning is required to map the reliability tasks to the identified constraints. A product with complex multidisciplinary integrated functions requires efficient reliability tools. These tools are required to be used to assess built-in safety and reliability features of the product under an...

This article intents to compare the applicability of mechanical compliance and the use of Pneumatic artificial muscles (PAMs) as actuators to achieve compliance in robot arms. PAMs were developed by using biological inspiration from human triceps and biceps in an effort to produce a manipulator with characteristics of a human arm. On the mechanical compliance, this article focuses on how material parameters can be adjusted to achieve mechanical compliance. Furthermore a comparison in applicability of either method will show that the two will function more effectively to achieve compliance if they are used together.
