About Sunday Robotics
Memo uses two arms, compact hands and a low wheeled base to perform selected household manipulation tasks. Sunday trains the platform using demonstrations collected by Memory Developers wearing its Skill Capture Glove, keeping routine data collection outside beta users' homes and using onboard autonomy for execution.
In March 2026 Sunday announced a $165 million Series B led by Coatue at a stated $1.15 billion valuation. The company says thousands of gloves have shipped and plans a public beta rollout in autumn 2026, with purchase availability only after beta feedback is incorporated into scaled production. Demonstrated chores and beta plans support late-stage development, not unrestricted home autonomy or current retail availability.

- Sunday Robotics previews ACT-2 laundry-folding model
2026-07-17 - Research Publication - The fixed checkpoint completed 778 folds across nine garment types without home-specific data or post-training; socks, bras, underwear and accessories were outside the declared folding scope. Successful folds took a median 2 minutes 13 seconds; 98.3% received four or five stars under a grading rubric fixed before evaluation.

2025-11-19 - Research Publication - Sunday presents ACT-1 as a robot foundation model trained without teleoperation trajectories, using human-aligned Skill Capture Glove data and Skill Transform to scale manipulation learning. The release highlights ultra long-horizon mobile manipulation (e.g., table-to-dishwasher) and zero-shot generalization in unseen homes with map-conditioned navigation. The post is dated November 19, 2025 on the company journal and serves as the primary research narrative for the ACT-1 / Memo stack.
