A charging system for an autonomous data machine may be provided. The system may comprise: a charging station, wherein the charging station has a low profile allowing the autonomous data machine to drive over to charge a power supply of the autonomous data machine automatically; and one or more processors of the autonomous data machine configured to make charging decisions to effect charging operations of the autonomous data machine that include charging time, charging location, and operations to be performed during charging. In some instances, the charging decision are based on at least one of the following: location of charging station, availability of charging station, mission parameters, locations of other autonomous data machines, and/or charging requirements and/or availability of charging stations.
