RHD is developed as a flexible hardware abstraction layer framework, that could be used in any application where interaction between a high-level control program and hardware devices are needed in real-time.

The main philosophy of RHD is the idea of a distributed variable database, making all communication variable oriented. A plug-in structure makes it simple to write interfaces to new hardware.
