def checkIfBall(self,**kwargs):
'''
N.B. This is a python generator, not normal function
Checks if the ball is already in the line of sight of the robot. saves a great deal of time that would be
wasted on searching.
It waits for 2-seconds, then decides by checking if the call back function has already added pan angles
to pan angles list.
Args:
self.blackboard["angles"]["pan"]
Returns:
Yields True : if the pan angles are greater than some constant values: meaning a ball is already spotted.
Yields False: otherwise
Parameters for optimization:
1. The constant term that defines how many pan angles there should exist to decide the ball is already spotted
Larger values => resistant to noise but may result to failure to detect the ball.
2. The delay time > before checking the number of pan angles.
Larger value > enough time to make sure a ball is not missed right under the nose.
Smaller value > good for speed.

N.B. This is a pyton generator, not normal function

self.scanning_tilt => tilt angle for search
Returns:
Yields True : After breaking out of for loop that turns the pan from left to right. Meaning
a ball was spotted during search.
Yields False: If it successfully searched over all range of pan angles 0-90 without spotting the ball.
Parameters for Optimization:
1.You can easily change the tilt search angle by chaning the variable self.scanning_tilt
2. By changing the constant added term when checking whether the ball is spotted or not; you can
change when the robot would consider a ball is spotted. Higher value means large noise reduction
but more delay time (or failure to spot the ball)
