Development of a robot to assist patient transfer

This work presents a robot to assist patient transfer. Using this transfer support robot, the nurse can transfer the weak, injured or paralyzed patient from bed to stretcher or from stretcher to bed by oneself. Moreover, the equipment can alleviate the suffering, stress and uneasy feeling of the patient. This work describes the concept of basic design, the construction of mechanism and the composition of control system. The control principle and algorithm of a new servo system are proposed. The experimental results of the synchronous motion for 4 motors and safety function based on current detection indicated the effectiveness of this system.
