Woooah! Super-frikin-cool!
Reminded me of 'Weebo' from the movie 'Flubber'.

Anwar sir, does it have coaxial props or some other mechanism?

I saw control surfaces moving inside with only one prop. And I only know as much about as you know :) 

Seems like the control mechanism is something like the VFO :

It feels like a Coaxial heli inside a spherical robot.
Coaxial heli provides lift, spherical bot moves the CG inside the body to make it move.

Nah, it's not coaxial. And it moves by using control surfaces and not by moving its CG.

that does seem the case looking at the number of control surfaces. But support for moving the cg and save a lot of power on the ground when rolling. i havent watched the video i am only inferring from the pics over the net.
