Human-like patient robot with chaotic emotion for injection training

In this paper, we present a system of patient robot developed with the aim at improving abilities of nursing student´s medical treatment, such as injection to vein. We propose to realize variable emotion of patient robot by using chaos orbit of non-linear time-differentiation equation. To evaluate the effectiveness of the robot through actual injection training, we measure heartbeat rate of nurse student during the injection training, proving the effects of the robot´s similarity to human. To make the patient robot to be self-contained for the training, we propose a 3D injector pose recognition method of patient robot to help that the robot behave autonomously along with the injection procedures of the nurse students trainings.
