Abstract: “With the growing trend of indoor mobile robots in the present day, such as elder caring and shopping helper, the issue of indoor robot navigation is becoming very important. In order to navigate mobile robots walk around in a room environment safely, the building of an indoor map is critical. However, the corner differentiation is usually becoming a significant issue. A robot should visit all corners and their consisting planes in a room correctly. Therefore, an efficient corner differentiation approach is essential for an indoor robot. In order to improve this issue, an effective corner differentiation is proposed in this paper to develop an indoor map building process.”
