Neural Network Manager for Lego Mindstorms NXT

Bram van der Vlist and Rick van de Westelaken have created a neural network manager for the NXT using Java. The training is done on a PC, then the trained network can be loaded and run autonomously on the NXT. Neat stuff! Read more here.

    Hi,

    I have justs encountered your Neural Network Manager application and have been trying to implement it. My aim is to get the robot to recognize some basic commands ie forward/back/spin. I can compile and run the Neural Network Manager PC application and link it with the RecSamples.nxj program.

    However I am unable to upload/run the nnTest.nxj program successfully as I get the following error: leJOS NXJ> Linking…
    an error occurred: Unsupported ldc in java.lang.Thread:.
    The following features/conditions are currently unsupported:
    – Too many locals ( > 255).
    – Too many constants ( > 1024).
    – Too many static fields ( > 1024).
    – Method code too long ( > 64 Kb!).

    Any ideas on how to solve this issue?

    I have only started learning about Lejos and mindstorms and can write/upload basic programs.

    Hope to hear from you soon.

    Kind Regards,

    Kurian Vithayathil
