Abstract
The development of wearable robotic technology has accelerated recently due to active research in industrial technology. Wearable robots are used to help patients with lower-body palsy to walk. This paper reports a generic wearable-robot monitoring system (GWRMS) that supports resource monitoring and status prediction. The GWRMS offers universal support for operating systems that comply with the Portable Operating System Interface (POSIX) application programming interface (API), reducing limitations that arise due to the choice of operating system and processor. This system improves optimisation of a program operating in a robot-embedded system by detecting overhead in the software process of the wearable robot. In addition, it operates using TCP-socket-based monitoring on an on-demand basis only.
Highlights
Robots comprise a collection of embedded systems whose performance is sometimes limited by the requirement for high portability and mobility [1]
The objectives of this study were to optimise the code for wearable robots and to predict their status by developing a generic wearable-robot monitoring system (GWRMS)
The GWRMS introduced in this study can be used with any operating system that conforms to POSIX standards, and it is not dependent on a specific process, architecture, or platform
Summary
Robots comprise a collection of embedded systems whose performance is sometimes limited by the requirement for high portability and mobility [1]. In some cases, embedded systems need to guarantee real-time performance. To address these requirements, previous studies have demonstrated methods such as kernel design to guarantee real-time performance [2,3]. The robot described in this paper assists with walking in patients with lower-body palsy. Since such patients can walk only by using exoskeleton robots, software optimisation is critically important. This can be achieved by monitoring the system resources of the wearable robot
