. . . #3you have your two lasers, each mounted parallel to each other, on a rail that allows you to separate them.you move to your tree, then slide them so that each one touches the side of the tree.your ir sensor is to 'see' that it touches the tree and reflects or not...measure the distance of your lasers, that equal the tree diameter

On a side note, this sounds like an attempt to replace a human with a machine. I think it is time we stopped doing that. It has been going on since the industrial revolution and, while it has made a few people very rich, it has not made humanity any happier....R
On the other hand, computers make everyone happier!
I thought that was Soma?
Really OT, but do you have to work 12 hours a day 6/7 days a week?
What about the leaves and branches and birds nests between the laser and the trunk?...R
Would you actually be less happy than you are now if you did have to (and did not know anything different)?You probably would not have been kept awake at night worrying how you were going to meet next month's repayment on the new car....R
