raising and lowering

you would need some form of linear actuator, in other words a motor that pushes a pole in and out, then im not sure cause ive never worked with them (yet) but i assume they have some form of control board which either comes with them or you buy extra and it would have an in and out switch and a cut off for when it has reached its maximum length or minimum. the issue you will then have is to fabricate the rest what the remote sits on where it slides in and out ect, from memory there is one done like that already on this site ill try find it

if its something like that i hope it helps this guy does really nice work, if you have time and a lot of it spare then you should read the whole article and look at all the pics https://www.the12volt.com/installbay/forum_posts.asp~TID~110922~PN~1~TPN~3
