Robotic Systems - Agriculture and Forestry Walking Forestry Manipulator Plustech Oy Finland Innovative technology is used among agriculture and forestry in order to increase the work´s efficiency. The Finnish company Plustech Oy has developed the world´s first walking forestry manipulator whose ingenious walking kinematics were copied from examples that Mother Nature provides. The computer- controlled, six-legged walking mechanism suits any of the various kinds of ground conditions that may be found in forests around the world. Yet it is designed not to harm the environment it is working in, e.g. its weight is at all times evenly distributed on the forest floor, and it prevents soil erosion. The device is controlled by a joystick and its claw is used to handle and move tree trunks.
