Re: 6 CIM Drivetrains... What's Your Experience?

Such a spreadsheet could help a team make the decision of whether 6 CIM acceleration is worth it or not in a few different situations:
- Robot attempting to 'turn a corner' around defense (i.e. get ahead of a defensive bot by 0.8-1.0 'robot lengths' in order to be able to turn in front of the defender and zoom away towards the goal)
- Robot attempting to beat a defending robot to a specific spot with N number of seconds to spare in order to get a shot off quickly
Back in early December I posted a large text file which lists the "time to distance" for a range of model parameters:

Would that be useful if I updated it for 6 CIMs?



Also, I don't know if you've seen it yet, but in mid December I modified the source to get the parameters from the OS environment (instead of being hard coded) and added a "ready to run" compiled executable attachment. It's at the bottom of the list.

The executable gets its input from the OS environment, which the user can edit in the script that runs the executable. The user can generate a variety of CSV files for various values of the parameters. In Excel these CSVs can be combined to get a single graph if desired.

If there's enough interest, I was thinking of integrating it with gnuplot so that graphing would be more seamless.
