What has been the hardest part of collecting training data for robotics projects?(reddit.com)

I'm researching how teams build datasets for robot learning and I'm curious what the biggest challenges are in practice. From what I've seen so far, collecting robotics data seems very different from standard computer vision datasets because you have to deal with sensor synchronization, demonstrations, real-world edge cases, and often much smaller datasets. One thing I'm still trying to understand is where most teams spend the majority of their time. For people working on robot learning, manipulation, navigation, or autonomous systems: Is data collection the main bottleneck? Is annotation and labeling the difficult part? Do you rely more on simulation or real-world data? What would you improve if you could rebuild your data pipeline from scratch? I'd love to hear some real-world experiences. submitted by /u/Vane1st [link] [Kommentare]
