Is it possible to create a routine by varying the height of the throws? For example, a high and long steering wheel on the right then a low and long steering wheel on the left?

Yes, launcher works automatically for distance, cadence and different horizontal and vertical angles. Also if these parameters are not enough to adjust your routine you will have to intervene manually to adjust the additional height thanks to the elevation column. Finally if you can not adjust your routine it may be too complex and you may be forced to move towards a more sophisticated device such as Aliobot BadRaptor.
