A couple pics from last week's mission. Ended up locating an average of 2600 feet of rail at 9 different at-grade crossings in just over 2 days. I know the instrument is at the edge of the head of the legs in one picture, but things don't always go as planned when trying to set up in ballast.
Cool!!

Ah yes, the ole legs in the ballast rock setup. It has to be about the most unstable surface material we have around here. I used to do A LOT of surveying for various railroad projects, and have set up in it hundreds if not thousands of times. This was my usual setup procedure: After the initial stomp and leveling of the instrument, I always used the leveling screws on the bottom of the gun to re-center over the point, re-level using the clamps on the legs, and a final fine tune leveling or two with the instrument screws. This keeps the robot from hanging off of the plate like that if it bothers you. I did it more out of necessity since not all legs have tri-max sized real estate on top.
P.S. That is a cool rail shooting rig you have there.

It used to really bother me that the instrument wasn't close to being centered. Now, as long as it's stable, I just roll with it. This is the only type of work that I do nowadays. The trolley is pretty amazing!
