.Net On Lego Mindstorm
troop23 writes "A blog posting by Benjamin J. J. Voigt says this "The University of Potsdam has a project to develop a .NET VM for the Lego Mindstorms system. Lego Mindstorms just got a higher priority on my shopping list!" While the thought of using .Net to program Lego Mindstorms may not be palatable, having a mainstream dev environment sure is." Perhaps Mono would work just as well.
Well there already are C/C++ compilers for Lego mindstorms, so writing a new one wouldn't add that much. Writing a .net VM however fulfills a new purpose. Whether it's really necessary or ideal is another argument, but it definitely provides more new functionality than writing another C compiler would.
Anyways, while you're right a VM is less than ideal for embedded systems, there are embedded Java VMs that people use and to a lesser extent there are people that use python and perl in embedded systems. Sometime it just makes sense to choose a solution that requires more computing power because it allows you to program faster. In fact, I think if there's any case of an embedded system where a VM isn't a big deal it would be one that's just for fun, not production, that is, the exact market of lego mindstorms. I mean, it's really a lot like Basic stamp microcontrollers. It doesn't make sense to build a product around them, but if you're just messing around with stuff there are plenty of people who don't mind paying more so that they can write their code quicker.
Still trying to catch up ... to Java, huh? This stuff has been around for Java for years now.
Which wouldn't be surprising since Java was released in 1996, while .NET was released in 2002. You could've said the same thing when Java was first implemented on an embedded device. C/C++ and assembly were likely there for years before.
Please elaborate why it would be a negative to provide the very robust .NET Framekwork to Lego Mindstorms.
I love how the editorial commentary on posts here is full of straw-men and assertions. Prav-dot anyone?

Too bad Sun can't produce cross-platform compatibility even within their own product line. For example, mobile devices use J2ME while PCs use the J2SE framework.
You will find a lot of the J2ME and J2SE are not binary compatible and barely source compatible if you try to port the simplest app. The "Write once, run anywhere" argument doesn't really stand up here IMHO.
Do you think those Java capable mobile phones have the full blown Java API on them, and run standard non-preverified class files?
Man what's with the bias against .NET. Oh it's not "worthy" of controlling Lego Mindstorms?
OH NOS! OMGZ, I R NOT HAX0RING MY LEGOS NLESS ITZ IN ASS3MBL3R. .NET BAD K PLZ THX! D0WN WIT MICRO$OFT!!!!111!1!
Seems to me .NET is a good idea, so good in fact it's ripped off by Mono. A solid intelligable foundation library of objects, inter language, cross platform compatability. C# is a very enjoyable language to work in for some of us (personal preference). There's always the /.'ers with monkeys on their backs that insist its one huge elaborate Microsoft bait and switch to lock everyone into the Microsoft Evil Empire, but it seems to me theres a ton of positives as well, ECMA standardization, dozens of .NET capable languages now, and the MONO project is a great thing (that is a direct result, like it or not, of .NET being born). So whats with all this "oh nos, its Microsoft, so I shall not dirty my hands of complimenting it! Must bash in every post ever!".
Open your minds like you open your source and you might learn something, like some tools are good for some jobs, other tools for other jobs. Not everything that comes from MS is evil and not everything that comes from OSS is good.
Flame away.

Perhaps Mono would work just as well.
'Mono' and '.NET' are not two competing products.
Mono is an implementation of it, together with some development tools and non-standard libs and bits and pieces.

I did a lot of lego design for a robotics competition I competed in last year. While legos are great because they are so easy to use, I can't stand using them for anything even slightly large in scale because of what I have dubbed "The Lego Design Flaw." Basically, there is a 6:5 ratio of height to width on legos which makes construction and reinforcement much, much more difficult than it needs to be when working in the full 3 dimensions that the Lego Technic allows one to work in.
