In order to support a wide range of sensors, two modules form the core of the Proteus platform. The robot is centrally controlled by an x86 based board with a low-power high-performance processor. This module runs a Linux operating system by default. A microcontroller module is also included to provide access to low level sensors and actuators. Together, these two modules allow for connection to a large number of varying complexity devices. In addition, such a dual architecture allows for the power, familiarity, and large code base of an x86 system without losing the configurability and precision of a microcontroller.
