##### RMF Calculator, Acceleration
« on: December 12, 2008, 08:12:23 AM »
In the Dynamics tutorial there is a section on determining desired acceleration. The instruction is to add together the horizontal-plane acceleration with the results of the incline calculation.

On the RMF Calculator, there is an entry for Desired Acceleration, and further down an entry for Angle of Incline.

My question: What value should be entered for the Desired Acceleration? The horizontal-plane acceleration (because the calculator uses the entered incline angle data to do the calculation and sum for you); or the calculated value (sum of the incline angle acceleration calculation and the horizontal-plane acceleration)?

How fast do you want it to accelerate? 3ft/s^2? 1ft/s^2?
Just enter that in.

Lets say you want it to always travel at least 5 ft/sec. Then you tell it that it must also go up a 30 degree incline. That means it will travel at 5 ft/sec at a 30 degree incline.

So if your robot was going on a horizontal plane it'll go *much* faster.

(hope that clears it up)

So the value placed in the Acceleration blank will be the acceleration the robot will try and hold while traveling up the incline placed in the Incline blank, correct?
