Fault detection and isolation in cooperative mobile robots using multilayer architecture and dynamic observers

Mobile robot systems are being used more often in tasks that protect human operators from dangerous environments, but these benefits can be easily lost if the robots spend much of their time being repaired. This implies that any increment in their …

Layered architecture for fault detection and isolation in cooperative mobile robots

This work presents an architecture that can help to increase the reliability in groups of cooperative mobile robots by taking advantage of analytical and sensor redundancy. First, the design of the architecture is portrayed and the faults to be …

Nonlinear state estimation in mobile robots using a fuzzy observer

The performance of model based fault detection and isolation systems can be improved by designing more accurate estimation methods. This work presents a novel implementation of a nonlinear Kalman filter based on the Takagi-Sugeno (TS) fuzzy …

Detección y diagnóstico de fallas en robots móviles cooperativos

The use of mobile robots has increased over the last years in a wide range of applications, which go from industrial work to more domestic tasks, such as vacuum cleaning or grass cutting. Due to the benefits that these systems bring and the …
