SYSTEM FOR HANDLING THE SEAMLESS TRANSITION OF BREAKLINES DURING AN EXCAVATION TASK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240018743 titled 'SYSTEM FOR HANDLING THE SEAMLESS TRANSITION OF BREAKLINES DURING AN EXCAVATION TASK

Simplified Explanation

The abstract describes a controller for an excavating machine that includes a tool, an arm, a set of sensors, and a chassis. The sensors provide data about the position of the tool. The controller has an input interface to receive operator steering commands and a computing unit to read a design model and reference the tool's position to the model. The controller is capable of performing a semi-automatic breakline-transition, which involves identifying a breakline-transition move based on the operator's commands and the tool's position with respect to the breakline. It also generates adjustment commands to align the tool to the breakline.

  • The controller is designed for an excavating machine.
  • It includes a tool, an arm, sensors, and a chassis.
  • The sensors provide data about the position of the tool.
  • The controller has an input interface to receive operator steering commands.
  • It has a computing unit to read a design model.
  • The design model consists of two interconnected polygons defining a breakline.
  • The controller references the tool's position to the design model.
  • The controller can perform a semi-automatic breakline-transition.
  • The breakline-transition move is identified based on the operator's commands and the tool's position.
  • Adjustment commands are generated to align the tool to the breakline.

Potential Applications:

  • Construction industry: The excavating machine controller can be used in construction sites for tasks such as digging trenches or leveling the ground.
  • Mining industry: The controller can be utilized in mining operations for tasks like excavating minerals or creating access tunnels.

Problems Solved:

  • Manual alignment: The controller eliminates the need for manual alignment of the tool to the breakline, reducing human error and improving efficiency.
  • Operator workload: The semi-automatic breakline-transition function assists the operator in performing complex maneuvers, reducing their workload and fatigue.

Benefits:

  • Increased accuracy: The controller ensures precise alignment of the tool to the breakline, resulting in more accurate excavation or leveling.
  • Time-saving: The semi-automatic breakline-transition function speeds up the process by automatically generating adjustment commands, reducing the time required for manual adjustments.
  • Operator assistance: The controller provides assistance to the operator by identifying breakline-transition moves and generating adjustment commands, making the operation easier and more efficient.


Original Abstract Submitted

a controller for an excavating machine, comprising a tool, an arm, a set of sensors and a chassis. the sensors being configured to provide data regarding a pose of the tool. the controller comprising an input interface and a computing unit. the input interface is configured to receive operator steering commands. the computing unit is configured to read a design model, comprising two interconnected polygons defining a breakline and to reference the pose of the tool to the design model. the controller is configured for performing a semi-automatic breakline-transition. the semi-automatic breakline-transition function including identifying a breakline-transition move based on the operator steering commands and the pose of the tool with respect to the breakline and generating operator steering command adjustment commands, based on the pose of the tool and the operator steering commands, in order to align the tool to the breakline.
