Embodied AI Glossary中文Sunday Robotics
AdvancedA US home-robotics company founded by the creators of ALOHA and Diffusion Policy, building the Memo robot.
Sunday Robotics, usually known simply as Sunday, is headquartered in Mountain View, California, and was founded by two Stanford PhDs: CEO Tony Zhao, an author of ACT and ALOHA, and CTO Cheng Chi, an author of Diffusion Policy and UMI. The company came out of stealth in November 2025, simultaneously unveiling the household robot Memo, the foundation model ACT-1, and a “skill-capture glove.” Its core approach skips robot teleoperation for data collection: instead, a person wears a glove structurally matched to the robot's hand and does real household chores, and that data is converted into robot-usable training data. In March 2026 it closed a $165 million Series B led by Coatue at a $1.15 billion valuation; it aims to deliver its first test units to 50 households before Thanksgiving 2026, and previewed ACT-2 that July.
ExampleMemo uses a single ACT-1 model to complete long-horizon tasks such as clearing an entire dinner table and loading the dishwasher, including in homes it has never visited before.
