Servo Controller
Can anyone tell me the maximum torque the continous rotation servo produces when it is loaded and speed is zero.· The· data sheet only shows torque for no load at max speed.·
Thanks For Your Help.

I'm not sure if you ment "will it move slower..." but if you did then it depends on the max torque of the servo. You probably won't see a difference in a really strong servo in relation to a light load but one where your load is close to the max torque it will strain the motor and slow it down, in which case you can up the speed to a limit by adding more pulses per second. You'd need some feedback as to how fast the servo is actually rotating though--an encoder or a through beam sensor or contact switch, etc...
Are you trying to maintain a constant speed with varing loads? The data sheets for most motors (not sure about servos) will have graphs of torque and speed with some other information there too like amps, voltage, ect...it might be worth looking for the data sheet from the manufacturer. The relationship is usually already there but only graphically, no equations are provided.
Just ask if you need more specifics on any of this, I'll try to help.
Take a look at the spec sheet:
Technical Specifications
> Power 6vdc max
> Average Speed 60 rpm
Note: with 5vdc and no torque
> Weight 45.0 grams/1.59oz
> Torque 3.40 kg-cm/47oz-in
> Size mm (L x W x H)
40.5x20.0x38.0
> Size in (L x W x H)
1.60x.79x1.50
I blieve·this·means that·47oz-in (inch ounces) of torque will "stall" the motor.
This is its "workload" if you will. I have no idea how to convert this to "towable" power. Friction in your drive system plays a part.
Maybe a reason for an experiment... Incrementally stack wight on your Bot and measure run speeds at various servo speeds...

Tommy, I know it wasn't designed to·x, but can you make it·do x·anyway?
