Title: Continuous Rotation Servo -- Motor Factor (RMF) Calculator
Post by: RpiHacker on September 15, 2014, 07:19:13 AM

Hey Guys - given that a continuous rotation servo is a geared DC motor it seems to me that RMF calculator could be used to to choose a servo for a small robot 2-3.0 lbs. for inclines of say 10-15 degrees with 4 drive wheels.

Is that a good or bad thinking?

Finding the upper limit of of CR servo use would allow for the use of say a 16 channel PWM/Servo Driver for Raspberry Pi, which in turn would allow for adding sensors, LEDs and other bells and whistles. Thus I could use a single homemade chassis to grow the robot so to speak.

Thanks for any advice you may provide.

Yes, it becomes a geared DC motor and you can use the RMF calculator.
R-Pi and the servo driver board will work.

Just be aware that the R-Pi runs a time-sliced OS and is not great for precision timing.
