Disclosed is an adaptive control method applicable to an excavator. The adaptive control method includes: acquiring detection parameters of the excavator, the detection parameters comprising a displacement of an electric control handle of the excavator and angle information of the excavator; identifying a current working condition of the excavator based on the detection parameters; and adjusting control parameters of the excavator based on the current working condition. According to the adaptive control method provided by the present disclosure, the current working condition is identified by using the displacement of the electric control handle and the angle information of the excavator, and then the control parameters of the excavator are adjusted based on the current working condition, so that the control parameters are automatically adjusted with change of the current working condition, which improves control efficiency of the excavator.

A system capable of improving accuracy of information relating to the degree of instability of a work machine such as an excavator, the information being provided to an operator of the work machine. Instability degree information, which indicates instability degrees Is1, Is2 of a base body (lower traveling body 410 and upper turning body 420) for which instability values have been assessed as continuous variables, is output to a remote image output device 221 (information output device) such that the form of the output varies continuously depending on continuous changes in the instability degrees Is1, Is2. An operator of a work machine 40 can highly accurately recognize the closeness of the current instability degree of the base body to a threshold value at which the base body becomes unstable, and consequently a tolerable range in which the work mechanism, etc. are operated while avoiding instability of the base body.

A power machine can include a frame, a lift arm, and one or more electrical devices for control of one or more work elements. The electrical devices can be controlled to improve positional accuracy for work elements during work operations, to improve power management and customer experience (e.g., to provide smoother ride during drive operations), and to provide float functionality for work elements.

Systems and methods for monitoring an attachment, such as a breaker head, for a mining machine. The system includes a breaker head, a wireless identification tag, a sensor, and an electronic processor. The wireless identification tag is coupled to the breaker head and includes a tag memory storing an identifier of the breaker head and an antenna. The sensor is configured to generate measurement data associated with the breaker head. The electronic processor is configured to receive measurement data from the sensor, generate a notification based on the measurement data, and transmit the notification to the wireless identification tag. Additionally, the wireless identification tag is configured to store the notification. The notification can then be later retrieved from the wireless identification tag by various devices, such as a further mining machine or a reader device of maintenance personnel.

A device may receive machine data indicating a pose of one or more components of a machine. The machine data may be generated based on first data from one or more first sensor devices associated with the machine. The device may generate validation data to validate the machine data. The validation data may be generated based on second data from a second set of sensor devices. The device may perform a comparison of the machine data and the validation data and determine, based the comparison, whether the machine data is validated or not validated. The device may selectively control an operation of the machine based on the machine data. Based on determining that the machine data is validated, the operation may be controlled based on the machine data. The operation may be controlled without the machine data based on determining that the machine data is not validated.
