We were thinking of using the highest noticed change in getEncVelocity() that appeared on a Smart Dashboard line plot for maximum acceleration, but if we donРІР‚в„ўt have consistent time units there it may be trickier than we thought.

Second, do you have any insight on how to accurately measure a robots maximum acceleration and jerk? WeРІР‚в„ўre trying to get motion profiling working, and are having a bit of trouble figuring out a way to find those out. We can put these constants into standard state-space notation using WPILibРІР‚в„ўs. Perhaps while IРІР‚в„ўm on here, though, I can ask a few more questions.Р”Р‡irst, do you know what time unit the CANTalonРІР‚в„ўs getEncVelociity() uses? I couldnРІР‚в„ўt find that information on the CTRРІР‚в„ўs API, though perhaps its safe to assume itРІР‚в„ўs seconds? If youРІР‚в„ўve used WPILibРІР‚в„ўs feedforward classes for SimpleMotorFeedforward or its sister classes, or used FRC-Characterization to pick PID gains for you, youРІР‚в„ўre already familiar with model-based control The kv and ka gains can be used to describe how a motor (or arm, or drivetrain) will react to voltage. The top graph charts trip time in milliseconds in green.

CAN Device Versions - String indicating the firmware version of devices connected to the CAN bus. WPILib Version - String indicating the version of WPILib in use.

In edit mode you can move around widgets on the screen and edit their properties. Official FRC Documentation powered by Read the Docs - frc-docs/driver-station.rst at main Setting the SmartDashboard display into editing mode The SmartDashboard has two modes it can operate in, display mode and edit mode. Though even if it is, I wonder if I can trust it with other dataРІР‚В¦ Each value displayed with SmartDashboard has a a set of properties that effect the way its displayed. I think the next time I have the robot in front of me (Saturday), IРІР‚в„ўll graph an actual timer objectРІР‚в„ўs data against it and see if thereРІР‚в„ўs any consistent correlation. Kinda feel silly now that I didnРІР‚в„ўt put that together. Thanks! Makes sense too, as it explains why I never found data between two time points.
