Prior to today, Team 8 was running voltage compensation on all of its Spark MAXs. We had a pretty low current limit set, but we were occasionally having brownout/jittering issues. Furthermore, we were always having issues where our arm would brown out when moving down while the drivetrain was accelerating hard. It turns out that when we removed the low current limit on the drivetrain, the drivetrain would jitter to a point that would make it impossible to drive.
After working with the CSAs here at the Great Northern Regional for about an hour this morning, we were ultimately able to track down the issue to the voltage compensation running on the Spark MAXs. In the next few days, I’ll go ahead and send a full report in to Rev Robotics, but I just wanted to put out a warning for teams using voltage compensation on the Spark MAXs.
