I have a platform that's attached to a rolling chassis by linear actuators. As the chaiis moves the wheels be be on uneven terrain but i need the deck to run up and down to maintain a fixed high.
Right now i have a rotating laser on a tripod sending signals to a laser signal receiver to give me absolute level now. The receiver drives the actuator up and down to keep itself at it's specified height level.
The laser set is big money and i would like to think of a way to do this with the arduino if possible. If i do this i can also customize some features and perhaps drive a display to show me relevant information. Can anyone think of a good way to find an absolute height?
*note - ground height will change so i cannot just sense the height from the earth
I am not against keeping the tripod rotating laser and attempting to just buy the receiver side as that end is the majority of the money. Think this may be do-able? I am not sure what type of receiver is would use for this.... would those rotators use IR? Just looking for some general ideas...... and i am sure i left out some major detail... so feel free to ask and i will try to paint as good of a picture as i can.
