Autonomous companion mobile robot and system

A system, comprising:

• a mobile robotic device, comprising:
• an enclosure;
• a first fog Internet of Things (IoT) gateway processor within the enclosure;
• a first memory device coupled to the first fog IoT gateway processor within the enclosure;
• a first plurality of sensors and input/output devices coupled to the first fog IoT gateway processor within the enclosure;
• and
• a first motion base, responsive to commands of the first fog IoT gateway processor, having a first housing coupled to the enclosure, the first motion base having a first plurality of wheels, wherein at least three of the first plurality of wheels are configured to drive and steer the first motion base on a surface;
• and
• a mobile robotic docking station, comprising:
• a second fog IoT gateway processor;
• a second memory device coupled to the second fog IoT gateway processor;
• a second plurality of sensors and input/output devices coupled to the second fog IoT gateway processor;
• a second motion base, responsive to commands of the second fog IoT gateway processor, having a second housing, the second motion base having an open recess therein, configured to receive the first motion base and at least a portion of the enclosure of the mobile robotic device, the second motion base having a second plurality of wheels, wherein at least three of the second plurality of wheels are configured to drive and steer the second motion base on the surface;
• and
• a lifting platform, responsive to commands of the second fog IoT gateway processor, within the open recess, and coupled to the second motion base, comprising:
• a lifting base configured to receive the first plurality of wheels of the first motion base thereon, and
• a fastener configured to releasably secure the first motion base to the lifting platform,
• wherein the lifting platform secures and lifts the mobile robotic device to space apart the lifting platform from the surface.
