Is there a maximum height or other physical dimensions for the excavation hardware?

There will be a tent around the sandbox, so the maximum height will be defined by that. To be safe, excavators should be able to operate without any part rising more than 1.5 meters above the regolith surface. This should provide enough space for excavators while also allowing for the umbilical suspended from above. In order to determine the maximum footprint for the excavation hardware, please be sure to look at the rules on starting position and orientation.
