Re: Ultrasonic Sensors
no, they wont give you and angular info. They will only give you the shortest distance read within the beam pattern. If you want to get angle info you can use two of these sensors (they will need to sound at different times to not get them confused) and by knowing the distance between the two sensors you can use trig to get angle info. We are thinking about using the camera to track the goal and then use the sonar to range. might be more accurate than the camera ranging.
