What you are looking for is Neuro Evolution. According to this paper you could be in a position to create a trainable feed forward Neural Network (some extra information might also be found here).

My recommendation would be to start small, maybe first start by making your character move and stop in the presence of danger. Neural networks can be rather difficult to debug, so start slowly to make sure that you have a solid base.

What type of neural network is suitable for simulating brain of virtual organism?
I never had any trouble finding wiper blade refills for my 1998 Honda Accord or 2000 Toyota Echo.  They were inexpensive because all you bought was the rubber part of the blade.  The steel strips to reinforce them were retained from the original wipers.

When my 2008 Nissan Frontier passenger wiper blade edge separated from the rest of the wiper I started looking for a replacement.  Refills I found claiming to be for my Frontier were usually refills for an after-market replacement arm assembly and did not fit my stock wipers.  I did finally find a Trico refill for my passenger side (18-240, narrow profile) but their recommended driver's side refill (24-240) is the same profile but needs to be wider (9mm vs 7mm??)

Local auto parts stores all say they stopped carrying OEM refills.  I could get a new wiper arm but years ago when I did that I regretted the poor quality of the replacement and the way it never quite fit the window as well.
