Days after emerging from stealth, the buzzy Silicon Valley startup Sunday Robotics has unveiled its autonomous humanoid helper for homes.
The Mountain View-based robotics firm says its flagship wheeled humanoid, Memo, will enter beta testing in late 2026 followed by a broader rollout. Sunday Robotics, which calls itself “the helpful robotics company,” positions Memo as a 24/7 household assistant that can clean tables, handle delicate glassware, picking up trash, and taking care of dishes.
According to the startup, hundreds of so-called Memory Developers are training the AI robot by wearing custom Skill Capture Gloves that record human motions. More than 2,000 of the devices have been distributed worldwide for collect data to train Memo’s onboard artificial intelligence.
Sunday Robotics, founded by former Google DeepMind/Tesla engineer Tony Zhao and robotics researcher Chi Cheng, began developing its first prototype in late 2024. The first iteration had only one arm and could only perform one task: arranging shoes. The humanoid’s skills have evolved rapidly. By October 2025, it could fold socks, handle glassware, and even pull a shot of espresso. Sunday says Memo now trains multiple household skills in parallel and adds new capabilities every month.
Memo stands 1.7 meters (5 feet 7 inches) tall and weighs 77 kg (170 lbs), with a humanlike build described as stable enough for industrial work. Its arms can reach 0.8 meters (2 feet 7 inches) horizontally and up to 2.1 meters (6 feet 11 inches) vertically. That’s enough reach to comfortable work across a standard bench and grab items from shelves above eye level. It has 20+ degrees of freedom (DoF), including seven per arm and four per leg. It moving speed is 1 m/s (2.2 mph).
The robot features a soft silicone exterior, a low center of gravity, and a lightweight frame designed for family environments. The startup says users can customize their robots with different colors and decorative hats. Its enclosure targets IP66–IP67-class protection, meaning it’s dust-tight and can handle heavy splashes or wash-downs typical of factory environments. Sunday insists that Memo does not rely on in-home teleoperation or constant human supervision, instead relying on learning collected off-site.
The startup has begun taking applications for its Founding Families beta program, offering early access, exclusive perks, and opportunities to influence the robot’s design. Pricing has not been disclosed.
Sunday Robotics is one of several US robotics startups racing to deploy their robots into homes. After Sunday teased its home humanoid, San Francisco-based Tangible Robots revealed its dexterous home assistant named Eggie. That startup’s CEO, Bipasha Sen, dropped out of an MIT PhD program to assemble the team that’s raised $4 million over two seed rounds.
Sunday and Tangible are taking a full-stack approach, developing their hardware and software in-house. They’re up against well-funded firms like Tesla, Figure AI, and 1X Technologies, which are taking dramatically different approaches as they race toward the consumer market. Tesla and Figure are planning to scale production of their autonomous humanoids in 2026, while 1X has opened preorders for its NEO robots. 1X’s humanoids, which cost $20K to buy outright or $499 per month, are expected to start shipping in 2026, with initial deployments relying on teleoperation for tasks that can’t be done autonomously.
