Driving WeddingBot was pretty straightforward. The amount the stick was tilted forward or back determined the overall speed and the left/right position determined how much it would veer left or right at that speed.

Holding the trigger button would turn on the fan so that flowers would launch out. The back button would switch left/right turn commands to make driving the robot towards you more intuitive

For the record, The Flower Girl even took a turn on the dancefloor. Who doesn't love a techy wedding!
