Okay, I've been through the calculations several times as have my students; and we keep coming up with the same answer. I am sending this out to the group to see if we are misinterpreting anything on use of the SoR motor calculator.

Our goal: select the correct motors for our robot.

Our criteria: based on the input parameters on the SoR motor calculator.

Mass = 6 lbs.

Desired Velocity = 9 in/s (0.75 ft/s)

Desired Acceleration = 0.4 ft/s^2

Expected Efficiency = 60% (treaded robot, rough terrain)

Incline Angle = 60 (extreme part of course)

Wheel Diameter = 2.5" (0.21 feet)

Powered Wheels = 2

We also specify a motor output rpm of 90. With this we get a required RMF that is pretty intense; so I'm hoping to get some feedback on what the group comes up with, or if I'm missing something.

I would appreciate any comparative data.

Cheers,
