Abstract

An automated spatial frame is disclosed. The spatial frame may include a master controller unit arranged and configured as a centralized controller for exchanging data with a remote computing system, exchanging data with a plurality of automated struts, and delivering power to the automated struts. Thus arranged, the master-controller unit may be configured as a fully integrated, rechargeable power supply/controller unit for powering and controlling the automated struts. In one embodiment, the master-controller unit is coupled to an external surface of a platform. The platform acting as a conduit for coupling the master-controller unit to the automated struts. As such, at least one of the platforms provides integrated connectivity to the automated struts. In one embodiment, the struts may be wireless automated strut including a motor, a power source, and a wireless communications module for communicating with an external computing system.
