Yes and that's the reason I added in the initial response: > Where will the main 'engine' for the robot run ? on the robot's controller ? > In > any case, for this use case you needn't touch java at all IMHO.

So again, how is the robot designed ? Where is the controller ? For example: is the controller one of the popular open hardware boards ? Basically, I was /highly/ recommend first designing the components and API that'll make up your system and then choosing the language. My personal recommendations: - A python based controller (perhaps twisted[1] based) - A javascript based UI If otoh, you want the controller itself running 'client' side completely (within the browser) you might want to muck around with NodeJS: http://nodejs.org/ Disclaimer: I have no experience with using this myself, but people whose opinion I respect say good things about it. hth, cheers, - steve [1] http://twistedmatrix.com/trac/ -- random spiel: http://lonetwin.net/ what i'm stumbling into: http://lonetwin.stumbleupon.com/ -- http://mm.glug-bom.org/mailman/listinfo/linuxers
