Abstract

The controller of robot or satellite is primarily implemented with electronic circuit. However, the controller circuit is vulnerable in the space. Faults and changing environment are two main factors that cause failure of the controller circuit. In order to survive in such harsh circumstances, an evolvable hardware method is used. In this paper, the robustness of evolvable hardware is analyzed in the case of fault and environmental change by means of modeling. Additionally, a circuit evolution experiment with four scenarios is performed, which shows the robustness of evolvable hardware in the two cases.
