The version of Imagine you have is probably good. In order to work with Robotnacka, you need a version that can load ActiveX components and thus extend its own functionality for new commands - for example commands that control the robot. If you got Imagine with Robotnacka, it is for sure good. Otherwise, the latest version that is distributed to schools in Slovakia by Infovek is also good.
You will see if your Imagine version is good when you try to create robot control ( new "oleobject [comname robot name r] - if this will work, your version is good!).
