Help with Object tracking

Hello guys,

I am planning to build a robot which will detect a movement and track it. By tracking i mean the face(ie going to be attached to a servo/motor) should move according to the movement of object. So basically i need a single servo/motor that moves according to the motion of object. Object can be anything : a human, animal, ball, etc....

Is it possible to do this?
Can i do this with ping sensors?
Which version of Arduino is best for this?
What kind of motor/servo is suited?

If the above details are not enough please let me know what more is needed?
I am new to Arduino based things so please be gentle :stuck_out_tongue:
Hoping some help here :slight_smile:

Is it possible to do this?

It is possible to attach a camera to a servo, and have the servo move in response to data from a PC to which the camera is connected. Object recognition and tracking is NOT something the Arduino can accomplish.

Can i do this with ping sensors?

If all you are interested in is distance to something, yes. Otherwise, no. The ping sensor can not distinguish a particular object.
