This is what I did during invites. from my experience you have 2 options (I'm assuming you're doing the bonus if you're trying to steer):
1. travel straight towards the cans and change the servo angle during the run to turn back towards the track (I did this and would not recommend, it is hard to do accurately).
2. If your servo isn't geared down already, gear it way down so you can utilize more of the servo's range of motion for accuracy and torque (a 90 degree change on the servo might be a 5 degree angle change actually, for example)
What exactly is gearing down the servo and how would i do that? Thanks for the reply.
