A program like Skype with auto answer for iOS? I have build a robot with a head actually made of an iPod (with iOS 6). I would like to take control of the camera remotely so I can control the robot from afar.

The program I need is very much like Skype, but I need to automatically activate the call as the robot is unattended.


The camera should not be activated all the time.
Unlike most camera programs, it has to be like a Skype call (video and sound both ways).


Skype allows you to do that but only on desktop version! 

I have searched for such a program/functionality and didn't find anything. I am actually thinking of adding one servomotor to answer the calls on the screen... ridiculous.

Ideally this program should work on my iPod with iOS 6 but a solution on iOS 8 or even Android interests me as well as a backup solution.

Any idea?
So I found another program that does almost everything and that is "usable" in my case, as Skype is not. 

Babyphone 3g

Pros:


It has the auto answer feature.
The camera can be turned off when not used.
If the connection is bad, it offers to take pictures.


Cons:


Video is only one way (big down) but sound can be both ways.
The "babything" design which makes it look unapropriate for me when it is the best I found.
Not free (and probably pay for each separate device you want to connect, have to check that)


I am not sure I should answer my question or edit my question in that case...
