Medical Robotic Bed to Prevent Pressure Sores

Patients who stay in bed for long periods are prone to pressure sores. Pressure sores cause multiple complications and prolong hospitalization. To prevent sores, the patient’s lying position must be changed continuously so that excessive on any body part does not last long. In this paper, we propose a novel robotic formation of This is composed segments driven independently by brushless direct current motors use information feedback control. By controlling movement top with fuzzy controller, kept below reference value. Moreover, belt-type sensor developed herein using force-sensing resistor technology measure pressure. A control system main teach pendant, motor controllers, sensors was implemented. Through real experiments, validity proposed robot verified, it confirmed closed-loop controller followed commands well.
