ACT-1: A Robot Foundation Model Trained on Zero Robot Data
Against the record
Memo, from Sunday Robotics, is at stage 1 of 5 on our ladder: demo only. Shown in videos or staged events; no units with customers. The latest milestone on its record is from 12 March 2026: Sunday said it raised $165 million, led by Coatue, at a $1.15 billion valuation.
This video comes from the maker's own channel, and makers show their robots at their best. The stage above comes from dated public records, not from the video.
