You would think that if you were to develop an AI system or a brain of a robot that it would be highly complex. After all with all the different things we can think of and when it comes to problem solving, it would certainly involve complex algorithms and programming, right? However it seems that a recent discovery has suggested that maybe less is more. Scientists at the University of Sussex have discovered that snail brains could be the key to helping develop smarter robots. The scientists attached electrodes to the brains of snails and according to their findings, the snail only used two brain cells to make complex decisions.
