I’ve been noticing a pattern in robotics discussions lately where most optimization effort goes toward models, hardware, or control systems, but less attention gets paid to the quality of the training data itself.

Especially for systems using vision or multimodal inputs, small issues in labeling or dataset consistency seem to create massive downstream problems:

• object annotations that vary between annotators
• edge-case environments that never appear in training
• inconsistent sensor synchronization
• data collected in conditions that don’t match deployment environments

What’s interesting is that a lot of these failures don’t show up immediately in testing, but later in real-world operation.

I recently read about teams like Unidata focusing heavily on the data preparation side for AI systems (collection, labeling, structuring for training), and it made me wonder whether robotics workflows underestimate how much reliability depends on dataset quality long before the model stage.

For people here working on robotics/vision systems:

• Where do your biggest data bottlenecks usually happen?
• Do you build datasets internally or outsource parts of labeling/annotation?
• Have you seen cases where improving data quality mattered more than changing the model itself?

Curious how others approach this in production environments.

I’ve spent the last couple of years chasing the next big thing and well... the screenshot speaks for itself. I’m currently sitting on over $4,700 in harvestable losses from positions like MSTR, RIVN and ACB.

My plan is to sell everything here and dump it into SCHD. Basically want to stop gambling and start building a reliable income
