Hi all, I'm getting some troubble and I think someone can help me. This weekend I built my first robot and it's working, but only if the bridges and the dc motors are power supplied with a wall plug adapter. When I use 4AA batteries it doesn't move. Can anyone tell me how to handle this? Maybe with some sort of batteries, like lipo or anything similar? Thanks in advance.
PS: I let some photos of the robot. The first one without the connections between arduino and bridges and without power supplies connected. The second one working but with the breadboard just for debugging and powered from the wall.
