Here’s some awesome NXT warehouse made by guys in Cubido Gmbh. These guys used microsoft BizTalk Server to manage SMS messages to the “warehouse”, SQL Server 2005 for data storage and web services. Microsoft Workflow Foundation to create the processes controlling the warehouse robot. and Microsoft .NET (C# and C++) to program the whole stuff. They also made their own electromagnet controlled via I²C bus.

Their webpages (mostly German) are linked here. A great trailer video (with Lego people animation..) for BigDays 2007 is here. Great work!
