Boe-Bot --> Does Voltage Input Change Servo Motor Speed?

Scope

I changed my batteries (again) in my Boe-Bot but this time, I put in 1.5 volt batteries, instead of the 1.2 v rechargeable batteries.

I thought I observed my Boe-Bot running around faster - is this true, does a variance in input voltage change the servo performance?

If so, why? I thought the input voltage was "fixed" with some sort of voltage regulator of some sort.

Thanks,

Yes, a higher voltage will produce more speed. But BE SURE not to go over a total of 7.2 volts. Higher than that and u will damage the servos. And running at 7.2 v will have a shorter life span than running at 5 volts. And the input voltage is regulated for the board of education & the bs2, but if you dont have the lil switch by the servo connectors set on vdd(5 v) than they are getting full juice from the batteries. I ran my boe bot from between 6.5 v and 7 v for almost 2 years and it's still truckin'! Your milage mat vary...

Not necessarily. It depends on how you have your servo voltage selector jumper placed. Take a look at the schematic: www.parallax.com/Portals/0/Downloads/docs/prod/boards/BOE_USB_D_Schematic.pdf
