I decided to implement a nice red switch for turning on and off this little robot.
Therefore I cut out a little piece behind the servo and placed the switch in there.
The place is just perfect for this switch.
I connected the two battery holder in series with AA batteries.
This gives me an output current of 2200mA and voltage of 9V.
Final:
You can see the little robot finally assembled.
