Abstract:
A machine includes a frame, a plurality of traction devices supporting the frame, an engine and an operator cab mounted to the frame, an implement system configured to move the work tool to a desired position, position sensors, a tilt-rotate system to move the work tool to a desired orientation, orientation sensors, an operator interface, and a control module. The control module is configured to receive a model of the work tool, receive boundary inputs defining a virtual boundary, receive signals from the position sensors and the orientation sensors, receive implement control inputs from the operator interface, determine a position and orientation of the work tool based on the signals and the model, determine whether the work tool is approaching the virtual boundary based on the position and orientation, the boundary inputs, and the implement control inputs, and automatically prevent the work tool from crossing the virtual boundary.
