Control System

The control system of Archie is based on a hierarchy structure with a central controller. The central controller which entitles an HydraXC50 (Xilinx Virtex 4 FPGA) is designed to run a Real Time Linux (RT-Linux) beside some application based hardware. For instance, the communication (back and forth) between the central controller and the joints of the robot is designated as a task for the application based hardware. As a rough explanation, the communication hardware used in the central controller acts like a graphic card. Detailed explanation can be found in related reference.
