"Motors that can do overkill"

Hi,

On this page:
https://www.societyofrobots.com/robot_tutorial.shtml

It says:

"get motors that can do overkill"

My first project will be ...

small 2 wheeled, differential drive, robot car
a third wheel (ball caster) for balance

Controlled by a Raspberry Pi and a RoboClaw

3" diameter wheels

My approach to pick an RPM was to walk 15 feet at a speed that I thought was OK for the car.

That took 7 seconds and about 19 revolutions of the wheel.

That equates to about 163 RPM.

My thought was to pick one of the micro-gear motors at ServoCity or Pololu.

Question: does "do overkill" mean I should pick a greater RPM like 220 or should I stick with the 163-ish range and pick a motor with more torque (hmm, but that could lead to a larger battery and more weight).

Thanks,
Bill
