We're indeed streaming the audio and have haptic feedback. My hypothesis is the seat vibration isn't as helpful. It's sub optimal and operators would be far more productive without it. We would do a paper when we have enough data on this. We're also putting more cameras but streaming a lot of them at once is tricky.

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.
