Abstract EN
A person following robot is an application of service robotics that primarily focuses on human-robot interaction, for example, in security and health care.
This paper explores some of the design and development challenges of a patient follower robot.
Our motivation stemmed from common mobility challenges associated with patients holding on and pulling the medical drip stand.
Unlike other designs for person following robots, the proposed design objectives need to preserve as much as patient privacy and operational challenges in the hospital environment.
We placed a single camera closer to the ground, which can result in a narrower field of view to preserve patient privacy.
Through a unique design of artificial markers placed on various hospital clothing, we have shown how the visual tracking algorithm can determine the spatial location of the patient with respect to the robot.
The robot control algorithm is implemented in three parts: (a) patient detection; (b) distance estimation; and (c) trajectory controller.
For patient detection, the proposed algorithm utilizes two complementary tools for target detection, namely, template matching and colour histogram comparison.
We applied a pinhole camera model for the estimation of distance from the robot to the patient.
We proposed a novel movement trajectory planner to maintain the dynamic tipping stability of the robot by adjusting the peak acceleration.
The paper further demonstrates the practicality of the proposed design through several experimental case studies.
