Move
Really consider if the points you are going for are = to the points you can loose. It isn't worth getting stuck next to a robot that is about to pour twenty balls into your trailer just to score one ball, for example.
If you can empty a ton of balls at once do it before trying to get a single 10pt b/c a lot of small balls add up faster, for the most part -- a lot of this depends on ur robot design of course
don't forget about ur human player (they've been a big determiner from a ton of points scored to tie braking fouls...)
And if ur robot is broken, don't try and run it, it is easier to move/protect a trailer than a trailer attached to a dead robot (and ur alliance will thank u)
Be sure to strategize with alliance members before round, some teams might need to closer work together to complete high scoring tasks than others and if picking an alliance take into account human players and the compatibility of ur robots not just pts scored (although this is important too).
But really, for most of the driver stuff it depends what you are comfortable with and ur robots capabilities. I'd say the safest thing is to do what u know best!
