Sunday Robotics released an evaluation standard called Solve and used it to showcase the laundry folding capabilities of their robotic foundation model, ACT-2.

Evaluation Highlights

Clearly defining task scope: clothing types, lighting, surfaces, initial placement, etc.
Explaining adaptation costs during evaluation: No need to fine-tune for every individual home
The same set of model weights can run directly across different homes

Results and Conclusions

ACT-2 achieved a 99.1% success rate in folding clothes in unseen homes
Scenarios covered various houses, lighting conditions, bed types, and clothing sizes
The team believes that pre-training on large-scale, high-quality human data will significantly enhance the model's generalization capabilities
The original post also noted: the model can even learn new folding techniques from a single example and transfer them to new environments
Memo plans to enter households later this year
