  ABSTRACT: This article presents the development of a timberjack-like pruning robot. The climbing principal is an imitation of the climbing approach of timberjacks in Japan. The robot’s main features include having its center of mass outside the tree, and an innovative climbing strategy fusing straight and spiral climbs. This novel design brings both lightweight and high climbing speed features to the pruning robot. We report our progress in developing the robot, focusing on straight climbing, behavior on uneven surfaces, and pruning. Key wordsPruning robot–Climbing robot

  ABSTRACT: A hybrid novel climbing pruning robot responding the requirement of sustainable forest management is presented. The climbing principal is imitated climbing approach of timberjacks in Japan. Main features include the locating of center of mass of the pruning robot outside of tree and the innovative climbing strategy fusing the straight and spiral climbs. Four active wheels are set at regular intervals around the tree allowing the robot to move along the tree. This novel design provides both lightweight and high climbing speed features of the pruning robot. The development progress of the robot with the experimental results of hybrid climb is reported here. Furthermore, the fuzzy velocity controller is also introduced with a promising experimental result.
