Abstract
A mobile machine includes a tool coupled to the mobile machine by one or more controllable linkages. The machine includes a user interface mechanism configured to receive input from an operator. The machine includes one or more controllers configured to implement surface follow logic configured to receive the input from the user interface mechanism and identify a desired movement of the tool relative to a control surface, based on the input. The one or more controllers configured to implement control signal generator logic that generates a control signal to control the one or more controllable linkages, based on the identified movement.
Claims20
A mobile machine comprising:
- a tool coupled to the mobile machine by one or more controllable linkages;
- a user interface mechanism configured to receive input from an operator;
- and
- one or more controllers configured to implement:
- surface follow logic configured to receive the input from the user interface mechanism and identify a desired movement of the tool relative to a control surface, based on the input;
- and
- control signal generator logic that generates a control signal to control the one or more controllable linkages, based on the identified movement.
A method of controlling an excavator, the method comprising:
- generating a control coordinate system relative to a control surface;
- receiving an input from an operator via a user interface mechanism;
- mapping the input to a tool transformation on the control coordinate system;
- and
- controlling the excavator based on the tool transformation on the control surface.
A control system for an excavator comprising:
- control surface logic that receives a control surface;
- user interface logic that receives user input from a joystick;
- binding correlation logic that correlates the user input to a movement parallel to the control surface;
- and
- control signal generator logic that generates and sends a control signal to a controllable subsystem to move a tool based on the identified movement parallel to the control surface.
