i m planning to buid a robot that uses sonar,initially i have planned for it to be stationary and detect objects in its(sonars) range.
My problem is to find an algorithm that can distinguish objects on a plane perpendicular to the (sonars) cone's apex.meaning if there are 2 objects on the same plane it has to identify obj.1 is at co-ordinate say 0,20 and obj. 2 is at 10,20
Please help!
