Gearmotors compared -- speed
Side-by-side comparisons

In the process of designing your 'bot, you'll also need to know your motor's rotational speed (at the output gear) -- this will tell you how long it needs to be powered in a given direction in order to turn a desired amount. Here's a chart comparing all the motors I've tested:

Gearmotor speeds (deg/sec)

Meanwhile, if you prefer to think in RPM (revs per minute), here's the chart for you:

Gearmotor speeds (rpm)

In both motor speed charts, the green zone is the (rough) range of rotational speeds of interest to walker builders.
