Headquartered in California, AI startup Sunday Robotics has emerged from stealth mode with the launch of its humanoid robot, Memo.

Designed as a domestic assistant, Memo is capable of handling everyday household chores such as washing dishes, doing laundry, and tidying up spaces.

In a demonstration video showcasing Memo’s capabilities, the robot is seen clearing tableware and loading it into a dishwasher.

The robot’s dexterity is further highlighted through tasks like handling wine glasses and folding socks.

Unlike many other humanoid robots, Memo forgoes legs entirely and instead navigates indoor environments on wheels, which helps maintain balance during task execution.

Notably, Memo’s training relies on real-world data collected from humans performing actual household tasks—rather than synthetic or simulated data.

The robot features modular, LEGO-like hands that synchronize with Sunday’s proprietary Skill Capture Gloves—wearable smart gloves that record and analyze how users perform various chores, including the precise grip strength needed to hold and lift objects.

Using these gloves, Sunday has compiled a dataset comprising approximately 10 million everyday household actions gathered from over 500 homes across the United States. This dataset underpins the company’s foundational model, ACT-1.

When announcing the dataset’s development in a blog post, Sunday stated: “There are 8 billion humans on Earth. Leveraging their everyday actions will enable us to become self-sufficient, break through data bottlenecks, and unlock large-scale robotics deployment.”

Sunday Robotics co-founder Zhi-Ming Zhao announced the release of the foundation model on X (formerly Twitter), writing: “We’re ushering in a major shift in robotic AI.”
