Sensing dump body characteristics and control

A material type identifier identifies a type of material loaded into a dump truck. When the dump truck is unloaded, a flow rate identification system identifies a flow rate of material exiting the dump truck. A flow rate controller automatically controls the tailgate actuator based on a desired flow rate of material exiting the dump body of the dump truck.

SELECTIVELY CAUSING REMOTE PROCESSING OF DATA FOR AN AUTONOMOUS DIGGING OPERATION

A machine may include an implement; one or more sensor devices; and a controller. The controller may be configured to receive, from the one or more sensor devices, data regarding a ground surface on which the machine is to perform a digging operation; transmit the data to one or more remote computing devices to cause the one or more remote computing devices to generate digging information based on the data; and receive the digging information from the one or more remote computing devices. The digging information may include information identifying a sequence of digging locations in an area of the ground surface and information identifying corresponding dumping locations. Based on the digging information, the controller may be configured to cause the machine to navigate to a digging location of the digging locations, and cause the implement to initiate the digging operation at the digging location.
