I have never used the OOpic before but . . .
I browsed the OOpic2 site, and it claims 'Within the OOPic IDE programming environment, you can choose to use Basic, C or Java syntax for your scripts.'
Basic is by far the easiest. But C is more powerful with more features, if you have some programming experience.
The OOpic looks fairly good to me, meaning it looks simple enough for a beginner, yet has good features you can use in more complex robots later on . . .
Keep us updated on your OOpic experiences!
