 | | RE: Robolab Documentation
|
| Although I shall not consider that as a manual, this is a very good reference book for intro to Robolab. Well, just say intro may not be fair either, as it does include some advanced concepts at the end of the book. It contains useful sample codes, (...)

I went to one held in my state, I was completely disappointed. It turned (...)

| A cry for help: I am trying to implement Ben Williamson’s Fetchbot (URL). I am happy that I have the mechanics right. The problem is that I want to emulate Ben’s code in Robolab.

| | | | | Re: questions on events
|

I've not used an event watcher to monitor more than one event (...) (21 years ago, 3-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)

I don't want to go through the long route which is to save the light values from different sensors to different container, then, compare them. How about using "formula (...)

Could you explain, in plain English, what exactly an 'Event' is? ...it's not a 'State' because it can be a constant or a variable. Yet you can have an 'Event Fork' which is (...)
