For example:
Task 1 needs object a.
Task 2 needs object b.
Task 3 needs object c.
If the robot could know the position of object a and c by method 1.
That means the robot use method 1 to prevent running object search module twice.
Therefore, I use times for object search module.
Which usage is correct, or totally not correct:
The robot saves two times of object search by using method 1.
The robot saves two object search times by using method 1.
Thank you~
