Re: First Neural Net implemented on a Lego NXT (C like, ROBOTC)
aah, you meant the NN topology:

as mentioned, I'd take a Feed Forward Net.
The number of neurons = number of output bits.

1 motor: at least 3 functional states (stop, forward, reverse)
1 neuron may encode 1 bit
10 motors: 3^10 combinations of functional states = 59049 states <= 65536 = 2^16 bits

so you need 16 digital outputs = 16 neurons to encode (control) the functional states of 10 motors

(sry for my poor English)
