Development of an automated wheelchair using RTK-GPS and LiDAR

Abstract

The purpose of this study is to make it safer and easier to get around using an automated wheelchair. In order to obtain highly accurate location information using RTK-GPS, a base station was set up at the university. We compared the errors of single positioning, RTK positioning using a distant base station, and RTK positioning using a base station installed in a facility in the university. As a result, the RTK-GPS system using the base station at the university had the highest accuracy. In the future, we plan to install RTK-GPS and LiDAR on a self-driving wheelchair to calculate the route to the destination.
