Various motor related parameters

[Pito Salas]

I don't have the spec sheets for my motors (as they came from my junk box) so I am guessing a little. 

Juan or anyone, can you help with these little clarifications? Thanks!

• MOTOR_MAX_RPM - Motor's maximum number of rotations it can do in a minute specified by the manufacturer.

  
  

  >>> I picked 200 but when I run the test motor script the fastest RPM I see is 145. Does it matter? Should I change it?

  
  

  
  

• MAX_RPM_RATIO - Percentage of the motor's maximum RPM that the robot is allowed to move. 

  
  

  >>> I set this at 0.7 just because my robot was showing that behavior that it turns a little every time it stops and one of your FAQs suggested this.

  
  

• MOTOR_OPERATING_VOLTAGE - Motor's operating voltage specified by the manufacturer

   >>> I have no idea about this. I put in 12V. Does it matter. Do I need to figure out how to measure it?

  
  

• MOTOR_POWER_MAX_VOLTAGE - Maximum voltage of the motor's power source. 

  >>>. Again No idea so I put in 12 again

  
  

• MOTOR_POWER_MEASURED_VOLTAGE - Measured voltage of the motor's power source. If you don't have a multimeter, it's best to fully charge your battery and set this parameter to your motor's operating voltage (MOTOR_OPERATING_VOLTAGE). This parameter is used to calculate the motor encoder's COUNTS_PER_REVconstant. You can ignore this if you're using the manufacturer's specified counts per rev.

  
  

  >>> I reverse engineered the counts per rev by experimentation.
