Cant' really answer about batteries since I haven't even connected mine yet. But what goes for usb connection I can tell you it is also very sensitive to it. I can only make it work with the cable that came with the arduino and connected to the computer. Any other combinations of cable/source don't work.
More in detail, when i mean work, i mean being able to control it from the zowi app. For example, I can connect it via usb to a usb charger and the robot might seem to normally start, but it doesn't answer to the app correctly (the app says it is connected though). In other cases it doesn't even start correctly at all and the app doesn't show it as connected either.

Servos consume a lot, and drop the battery voltage under 5V or 3,3V and reset the arduino, to solve this add this circuit: (consider 6V instead of the 5V of the image)
For the capacitor use > 1000uF and > 6V
In order to make Bobwi work to the app, you have add a button for A0, or just a single wire, and touch it, to make Bobwi change to app mode.

Hi All,
There should be problem with Nano Sheild, it can't go through big currents, I think. What my solution is as below.
- 5V power supply directly, using LiPo battery with 5V/4A rise circuit.

many thanks, G4lile0.
Haven't try you diagram yet, need to learn more basic electronics, circuits.
@poyaque-estamos i got no problem when using USB cable control Bobwi over bluetooth
