I just marched up to it in heavy power armor and used a control laptop to disable it. The first time I tried the same thing, I didn’t have power armor, so I stutter-walked squares of opaque terrain up to it (book-cases, if I recall correctly). But that time, it self-destructed. Another method would be to build a light 3x1, or u-shaped, vehicle out of opaque vehicle tiles and push it up, if you have enough strength, or drive it up, if not.
