Hi all, I got some examples running without errors reported. But sincerely I
could not understand what should I look at those examples. I mean, is there
any control algorithm running? I pressed up/down and right/left keys and I
got a men walking around. Do you have any tips to improve my experiences
with ors?
I installed yarp following INSTALL file but I didn't get yarpview installed.
I think it's fundamental to get properly advantages from some examples.
Thanks,
Breno
