An SPN Modeling of the H-IRW Getting-Up Task

This research study here deals with the Stochastic Petri-Nets (SPNs) modeling of an interacting task (getting up from a sitting position) in a human-machine interaction model. The machine is an Intelligent Robotic Wheelchair (IRW) appropriately modified to provide assistance to a human user, who utilizes the IRW. SPNs are recognized as useful modeling tools for analyzing the reliability and performance of systems through time, which is the main reason of choosing them. The main use of this model is to simulate the procedure and eventually used by people with disabilities and the elderly with ultimate goal to improve their daily life. They will get up from a sitting position with the help of the wheelchair, which has robotic arms attached to it. If not for the IRW, these people would need the assistance of another person to get up. Simulated results will be provided from the stage of this study.
