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.

System for handling the seamless transition of breaklines during an excavation task

A system for controlling movement of multiple links of an excavator can move a tool at the end of an excavator arm. The system includes a sensor data interface configured to receive sensor data for determining relative orientations of the multiple links with respect to each other, and a surface setting unit configured to access design data defining a reference surface. The system has a remapping unit configured to remap a user command for moving two links with respect to each other about a corresponding joint to a rotatory tool degree of freedom. The system then coordinates output signals, such that as a function of the remapped user command the tool is rotated within the associated rotatory tool degree of freedom, without the need that an operator coordinates underlying joint movements.
