Three-dimensional sensing system for agricultural robots

Abstract

A three-dimensional sensing system that consisted of a laser scanner and a lift was developed for agricultural robot to capture precise external information. The laser scanner was moved vertically by the lift to collect three-dimensional distance information around the robots. In the experiments by using a laser scanner and a color camera, each tomato fruit in a same cluster was discriminates successfully. Furthermore, the sensing system detected not only objects but also human motion around a robot when infrared sensors were added to the sensing system.
