Home Robot ACT-2 Achieves Zero-Shot Laundry Folding
tonyzzhao · x · 2026-07-17
Sunday Robotics has previewed ACT-2, a foundation model for home robots designed to "work reliably even in unseen home environments."
Key Results
- Achieved a 99.1% zero-shot success rate in folding laundry across diverse, unseen home settings.
- Conducted 785 autonomous attempts, covering 9 types of clothing.
- Average rating of 4.72/5, with a median completion time of 2 minutes 13 seconds.
Highlighted Approach
- Massive pretraining is used to bridge the gap between lab performance and real-world conditions.
- Building on this, a single demonstration is enough to teach new folding techniques that generalize to unseen garments.
- This enables quick fixes for failure cases using minimal on-site data, with the fixes continuing to generalize.
The core conclusion: the real challenge isn't demo room performance, but reliability in unfamiliar homes.
