Mobile platform and method of assembly thereof

A method of assembling a mobile platform for an autonomous mobile robot, the method comprising the steps of:

• constructing a structural frame;
• providing a central unit configured to conform to an internal form of the structural frame and having a substantially planar form, the central unit comprising a power source and a controller;
• and
• mounting a wheel set to the structural frame the wheel set comprising a plurality of wheel units each coupled to the structural frame and at least one wheel including an in-hub electric motor,
• wherein the structural frame comprises a closed shape extending around a periphery of the platform and defining an open central region into which the central unit is mounted, and wherein the structural frame comprises:
• a plurality of elongate beams,
• a plurality of connectors, each connector receiving and mechanically coupling adjacent ends of respective elongate beams, of the plurality of elongate beams;
• and
• at least one of the plurality of connectors being a multifunctional connector which further comprises one or more integrated electrical interfaces for the central unit,
• wherein the elongate beams are sections having a constant cross section, and
• wherein the elongate beams are each formed with at least one longitudinal groove formed in a surface of the beam and extending longitudinally along a length of the beam.
