Described herein are systems, methods, and other techniques for determining a period during which an implement of a construction machine is interacting with a ground surface. A vibration signal that is indicative of a movement of the implement is captured. One or more features are extracted from the vibration signal. The one or more features are provided to a machine-learning model to generate a model output. An implement-on-ground (IOG) start time and an IOG end time are predicted based on the model output, the IOG start time and the IOG end time forming the period.

Implement-on-ground detection using vibration signals

Systems and methods for providing grade control on a motor grader without the use of masts attached to the blade. Embodiments include a body angle sensor configured to detect movement of a construction machine's body, a front 3D positioning device configured to detect a geospatial position of the construction machine's body within a world space, a drawbar angle sensor configured to detect movement of the construction machine's drawbar, and a blade angle sensor configured to detect movement of the construction machine's blade. Two positions on the blade may be calculated first within a machine space and subsequently within the world space. Movement of at least one articulating connection may be caused based on the blade positions within the world space.

Motor grader 3D grade control

Systems and methods for providing grade control on a motor grader without the use of masts attached to the blade. Embodiments include a body angle sensor configured to detect movement of a construction machine's body, a front GNSS receiver configured to detect a geospatial position of the construction machine's body within a world space, a drawbar angle sensor configured to detect movement of the construction machine's drawbar, and a blade angle sensor configured to detect movement of the construction machine's blade. Two positions on the blade may be calculated first within a machine space and subsequently within the world space. Movement of at least one articulating connection may be caused based on the blade positions within the world space.
