-BRUSH
PRF-BRUSH, or Perceiving Robotic Forest-BRUSHing, is an autonomous robotic forestry system developed by the University of Wisconsin-Madison. The system uses a robotic arm to detect and remove large weeds and other plants that crowd out native forest species. The robot has two vision-based cameras providing 3D stereoscopic imaging and laser range finders that allow it to detect the plant and analyze the size, shape, and density of the plant. The robot is also equipped with a series of grippers and brushes that can be used to grasp, manipulate, and remove the offending plants. This system has been used in a variety of environments, such as residential yards and golf courses, to help manage natural resources in a sustainable manner.
