Faster Continuous Rotation Servo

Is there a way to speed up the Continuous Rotation Servo supplied by Parallax or will I have to buy a faster servo and modify it for Continuous Rotation?

I notice that w/ the old version of BOE Bot, you had to modify a regular servo and I remebered it being faster than the servo that came w/ version 2. Did anyone else notice this?

    It would depend on the gears in the servo. But remember faster means less powerful.

    I believe that the servo is over geared - the wheels 'slip' rather then stop or when the robot is trying to ramp a wall.

    I will have to open the case up again to see if I can take out or replace any gears .. but it seems unlikely. I was hoping for something like powering it on higher voltages or changing the controller board.

    If you're slipping instead of stalling, you've still got more power than you need (at least so far), you just don't have enough friction. You might want to try adding some weight.

    Keep in mind, this slippage might be a good thing, it may prevent the servo from stalling, and creating a blob of melted plastic smile.gif

    More voltage means more speed... depending on your servo, you can drive them with a bit more voltage (just realize that you may also shorten the life of the servo... I have driven them with up to 12 volts (8 AA batteries) and have not had a problem yet (but I also don't run it for very long at a time)
