Study on a New Type of Clearing Stump Robot

Abstract:

A new type of clearing stump robot was developed to raise the efficiency of removing stump and reduce the damage of the ground surface in the cut over land. The robot mainly consists of a walking mechanism of a caterpillar excavator and a manipulator. It was controlled by a computer system based on the machine vision. The operating radius of the manipulator was 4-8 m, and the maximum stump cutting diameter was 0.55 m. The practical test shows that the robot can clear about 100 stumps per day (6 hours) compared to 45 similar stumps by hand-held implement. The efficiency of the robot is about 20-25 times than that of a worker. Especially, a hole of less than 1 m² is formed by the robot compared to 10 m² ground surface destroyed by employing another uprooter to clear a larch stump.
