Design and Analysis of Novel Nursing Transformative Assistive Robot Comprised of Transfer and Omnidirectional Carrying

Abstract

In this paper, we present design and analysis of a novel nursing lift and wheelchair which can run towards omnidirectional on the ground. The proposed assistive robot provides a power assist function for transfer aid system with hoisting, and also an omnidirectional motion function using DDSS (Differential Drive Steering System). By transforming the length of Boom, Shaft, and Leg Parts, novel power assist robot can easily transfer the person from wheelchair to bed, and vice versa, and furthermore can carry the person as a wheelchair. To show the usefulness of the proposed robot, several experiments with a series of nursing operation have been done in the present research.

Healthcare Robots and Smart Hospital Based on Human-Robot Interaction

“…Until now, two types of nursing care equipment, a patient lift, and a wheelchair have been required to assist with transfers and transportation in the nursing care field. Therefore, we analyzed these processes and proposed and fabricated an omnidirectional power-assisted transfer/transportation integrated care robot that combines an omnidirectional transfer mechanism and a power-assisted lift mechanism, with the aim of performing these tasks with a single robot (Figure 4) [17,18]. A mechanism that can be transformed to the required size at the time of use was designed to enable use in the home.…”
