Communication SoC based on 1oo2D architecture for industrial human-robot-collaboration

The mechanical force imparted by industrial robots is enormous and can lead to dangerous situations for human workers and property if they malfunction. System designs based on the redundancy concept are essential to avoid or mitigate the resulting risk, which is recommended by the various safety standards. In this paper, a 1oo2D based safety SoC that provides multiple Ethernet communication interfaces is presented. Two different design approaches are implemented using the in-house FPGA development board based on the LEON3 soft processor. The software algorithms for each approach are developed and verified.
