Re: [simspark-devel] The angle in the horizontal plane.

[Stefan G. <gla...@gm...>]

Hi Feng,

I will check the description of the wiki once again according to our 
agent-implementation.
But since I did this already several times, I hope there is no error 
left any more.

Keep in mind, that the camera is located in the center of NAO's head - 
but the pitch axis of the head is located a bit below. Since your 
changes are relatively small, this could already be an indicator.
On the other hand, you could also try to look sidewards and check the 
second angle, which is provided to you. This way you can cancel out 
other values...

Good luck,
Stefan
