Sunday Robotics previewed ACT-2, saying it reached 99.1% zero-shot success on laundry folding.
- 785 autonomous attempts across 9 garment types
- Unseen homes, no per-home adaptation, one fixed model
- Handles sizes from XXS to 8XL
- 4.72/5 average fold quality and a 2:13 median completion time
The company frames this as single-demonstration learning that generalizes to new environments, with post-training gains transferring directly into real-world performance.
A reply in the thread also mentions Walden Robotics, which reportedly came out of stealth at a $1.1B valuation with $300M co-led by Toyota and Deviation Capital, and says its robots have already been in production at a Toyota plant since February.
