Fault tolerance has always been a standard feature of electronic systems intended for long-term missions. However, the high complexity of modern systems makes the incorporation of fault tolerance a difficult task. Novel approaches to fault tolerance can be achieved by drawing inspiration from nature. Biological organisms possess characteristics such as healing and learning that can be applied to the design of fault-tolerant systems. This paper extends the work on bio-inspired fault-tolerant systems at the University of York. It is proposed that by combining embryonic arrays with an immune inspired network, it is possible to achieve systems with higher reliability.
