Hi There is just the robot tutorial, chapter 1 (www.berniw.org, follow the links). This might give you an insight (->what are the inputs/interpretation/ranges). Basically you do not need to worry about a lot of stuff in human.cpp, because loads of code there just handle various input sources. What hepls me when digging into unknown projects/sources is to just roughly map the big blocks and hold myself back in wasting time with trying to understand details which are not required for my task;-) This way even huge projects can start to look handy;-) Best regards Bernhard On 10/02/2013 08:42 AM, khushali modi wrote: > Hello Bernhard, > > We started reading code in human.cpp and client project, we are able to > navigate the code faster but still we are facing a lot of problems > understanding everything in the code.
