rate of distance change 3

very simple with fast updating and i think it's pretty accurate

big issue is that the numbers can jump around at slow speeds especially at high fps
even if you change the speed of the actuator

this is probably because the actuator is moving too slowly at these low signals which also means a higher prox maximum will be problematic.
a possible solution is to have two or multiple sets of prox sensors and nas sensors that activate and deactivate and certain thresholds to keep the actuator moving fast enough.

you dont need this fast of an actuator but faster is better, to a certain point


you can use and upload
