Create a power circuit so that the robot can run without being tethered to a laptop

I think we don't need a 3.3 V voltage regulator. If we connect 5V to either the BAT or the USB pins on the ESP8266, the onboard regulator will produce 3.3 V, the same way it does if a USB console cable is connected.

Oops, hit send on that last note by accident. Great news about the power, hoping we do not cook our boards!

I did not work on the robot when you left, but I did look into the serial over ip stuff a bit. I think I will continue working on the ip socket code angle as that serial wifi stuff seems to need special boot loaders and possibly hardware to make work.
