I have seen other teams use the inertial sensor with a lot of success but if you are inexperienced and don’t know how to do PID the inertial sensor will be a little innacurate. If you use the built in smartdrive function turns will be plus or minus 2 degrees off of the target and most robots don’t instantly stop so if you code the robot to turn 90 degrees without PID it may turn 100 degrees. Even so you’ll probably be able to achieve decent accuracy and make a fairly consistent auton by making the chassis run at half speed.
