In this article we propose an intelligent system (IS) for automatic movements of a robotic-assisted hospital bed, it is based on posture classification and recognition using mattress pressure sensors. The proposed IS allows to program a sequence of movements of the robotic bed that are executed automatically through electric actuators in response to the pressure distribution of a patient on the bed. The experimental results show that programmed movements are useful in preventing bed-sores in patients who stay in bed for extended periods of time.

Keywords: Pattern classification, support vector machines, pressure sensors, intelligent systems, assistive robotics.





We would like to thank the CGSTIC-Cinvestav IPN team for making this development possible. We are also grateful to the medical staff of Hospital Juárez of Mexico for their help.
