But where is no information about using of NXTRadar on that page. So I decided to use it as a regular sensor. I did something like this:

It's say something like 'unknown primitive'. I think it's because incompatibe version of VM(I have version 0.7). I try to download new version from NXTalk project webpage. But its 0.7 too.
