In the   last post I was playing with 4Tronix's   Bit:Bot . In this post I will show the initial experimentation with an artificial neuron controlling the Bit:Bot to follow the edge of a line (it follows the left-hand side of the line). The neurons (well two separate ones, S1 and S2) are produced using weighted sums - summing the weights x inputs [ right-hand sensor (rs) and left-hand sensor (ls)] plus a bias for each neuron in this case w[0] and w[3].                         net=w[0]+w[1]*rs+w[2]*ls           net2=w[3]+w[4]*rs+w[5]*ls   If weighted sum >=0 then its output 1 otherwise 0       if net>=0:          s1=1     else:         s1=0     if net2>=0:         s2=1     else:       ...
