I am quite new to nxj at this stage and my intention was to use some software for my ballbot project (i.e. balancing the nxt robot on a ball). I found several methods on the website but it seems that I cannot apply those successfully on my robot.. I came across this nxj occasionally on a youtube video using nxj to program ballbot which is quite interesting. I do find there exists a ballbot class in lejos that can be applied to balance the robot. It looks quite easy to do but I'm just wondering is there any example codes associated with the ballbot application that can be given? Or any suggestions/hints about how to get started to use nxj for my ballbot project would be highly appreciated.
