I'm bumping this thread to link to the
Luminary Micro's Jaguar Motor Controller Characterization thread on the First Forums and attaching a copy of the excel sheet (for those who are not FIRST Forum members). This is obviously very important data for everyone to consider when controlling their robot and I am glad they can provide it to us so early in the process (thanks Joe Hershberger ).
EDIT: I started writing this post before Joe Ross posted (beating me to it) but got side tracked. I guess we think alike for where to post this data in this older thread.
A few comments: I am impressed with the linearity of the CIM Speed vs Pulse Width. However, I am not sure (and not qualified to speculate not a ME) how well this will linearity will translate to speed of a motor under load (normal 4 motor drive of 130 lb bot). In my experience, at lower powers on the victors the drive motors just hum so will the jaguars just hum (depending on gearing obviously) for a the lower portion of these graphs. Maybe a fast rise like the victors is better in this case?
