What documentation is available with the Java source files? All can see are java files, no instructions on what you’re suppose to do with them. You really should explain that part better IMO.

Hi,

Great article and I am eager to use this application, however I am running into a couple of problems:

“failed to load main-class manifest attribute from neuralnet.jar”

I receive the same error with the Jar file provided.

Additionally, when trying to compile the source, eclipse throws an error that the catch statements within connectUSB()/connectBT are unreachable. I have removed this but it seems to produce more errors.

Any ideas?

i have a error every time i tried to run the “neuralnet.jar” file

it says “failed to load main-class manifest attribute from neuralnet.jar”

someone know how to solve it?

This application is very interested in. I try do design to application in biomedical. How do you thing about that ? It is possible ? If you can give me some idea ? Thanks !

The Mindstorms NXT 8527 is my cup of tea. Simple enough for a ten year old, but challenging enough to allow continual growth in the robotics area. Your article mentions PC, but it is Mac compatible as well, right?

Hi,
the example is very nice. I now use lejos 0.6 and if I try to link nnTest I get the following error message:

leJOS NXJ> Linking…
an error occurred: Unsupported ldc in lejos.nxt.Button:loadSettings.
The following features/conditions are currently unsupported:
- Arithmetic or logical operations on variables of type long.
- Remainder operations on floats or doubles.
- Too many locals ( > 255).
- Too many constants ( > 1024).
- Too many static fields ( > 1024).
- Method code too long ( > 64 Kb!).

What lejos platform should be used with the example?
Regards
Rainer

[...] 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. [...]
