Tobbe, This is a nice looking model, especially with all the functions. As to more traction, you could use alternating regular chain links and tread links and mount a 1x4 plate on each tread link, studs out. I'm not sure how realistic this would (...)

I forgot to metion.. a very good, and practical book on Neural Networks is "Machine Learning" by Tom M. Mitchell (1997). Includes theory and examples. But working with Finite State Machines is a much more reasonable starting point for RCX. rama (25 years ago, 4-Nov-00, to lugnet.robotics)

You picked a challenging project. It is not possible for the RCX to do Neural Networks alone, since the RCX does not have the command set, and is not a fast enough processor to calculate the weights of the Neural Network. Also, the RCX doesn't have (...) (25 years ago, 4-Nov-00, to lugnet.robotics)
