Humbly, have you used excavators of varying sizes on uneven ground? I have and would suggest it's more important than you might think. But if you've operated them, you might know better than I.

Also, teleoperation is likely to produce lower-quality operation data than hooking up to locally operated excavators. Just a thought.

I might be less experienced than you - I've operated upto 38 tons on maximum 15 degrees incline. I wasn't moving tracks a lot when I did that. Would like to hear what scenarios you'be been in and how would you describe your experience? Maybe I could try those out to learn more!
