- A team built a budget-friendly robot vacuum under $500, aiming for weekly charging.
- Used behavior cloning with a CNN on teleoperated image-action pairs for navigation.
- Encountered issues like false positives, oscillation, and poor depth perception during testing.
- Experiments with data augmentation and ImageNet pre-training didn't reduce high validation loss.
- Future improvements include using frame history and collecting cleaner, more consistent data.
- The project was completed part-time in 4 months, meeting budget but facing limitations like weak suction and manual intervention needs.
