On the Effect of the End-effector Point Trajectory on the Joint Jerk of the Redundant Manipulators [PDF]
Journal of Applied and Computational Mechanics, 2021 This paper is focused on investigating the joints jerk of industrial serial redundant manipulators with 6 degrees of freedom (6-DOF) under the variation of the end-effector point (EEP) trajectory in the workspace. The EEP trajectories are initially built

Responsibility Assignment in Redundant Systems [PDF]
Current Biology, 1970 Redundancy is a fundamental feature of biological motor systems. For example, when touching an object, many different combinations of movements of the shoulder, elbow, wrist, and finger joints result in the same movement at the fingertip. Exploiting this redundancy, the motor system distributes work across effectors to minimize signal-dependent noise ...

Active-Redundancy Allocation in Systems [PDF]
IEEE Transactions on Reliability, 2004 An effective way of improving the reliability of a system is the allocation of active redundancy. Let $X_{1}$, $X_{2}$ be independent lifetimes of the components $C_{1}$ and $C_{2}$, respectively, which form a series system. Let denote $U_{1} = \min ( \max (X_{1},X),X_{2})$ and $U_{2} = \min (X_{1},\max (X_{2},X))$, where X is the lifetime of a ...

Mathematics, 2020 The paper provides reliability analysis of a cold double redundant renewable system assuming that both life-time and repair time distributions are arbitrary. The proposed approach is based on the theory of decomposable semi-regenerative processes.

Maintenance Model of Digital Avionics
Aerospace, 2018 The cost of avionics maintenance is extremely high for modern aircraft. It can be as high as 30% of the aircraft maintenance cost. A great impact on the cost of avionics maintenance is provided by a high level of No Fault Found events (NFF). Intermittent

A proposal of system to improve software reliability
Studies in Science and Technology, 2021 System failures include hardware failures and software failures. However, most of them are software failures. A redundant system is usually used to improve the reliability of hardware, but even if the same redundant principle is applied to a software ...
