Hey, I have a BOE bot chassis with an Arduino mounted ontop. I have two high speed continuous servos for the wheels and an 4 pin ultrasonic sensor. For power I have 4 AA batteries powering the arduino.... this does not work very well, the four AA bateries do not supply enough power. So I thought that I could power the two servos with the 4AA batteries and a seperate 9 volt battery simply for the arduino and the 5v ultrasonic. But I hear that the power of the servos must be 'regulated' how can this be achieved? how do you regulate the power? I have limited space on board the chasis and so hope that the need for resistors and or other transistors is not needed. Thanks!
Heres the specifications on the Servos and ultrasonic,
