ui44 currently tracks 331 robots from 202 manufacturers across 9 categories. This includes 210 commercially available robots and 121 in various stages of development or pre-order. The database is continuously updated as new robots are announced and existing products receive updates.

Robots in our database range from $125 (StackChan) to $1907k (Bespoke AI Jet Bot Steam Ultra). 146 of 331 robots have publicly listed prices. The remaining robots have enterprise-style pricing available on request from the manufacturer.

Use the sort dropdown on this page to order robots by "Price: Low to High" or "Price: High to Low." You can combine the price sort with category and manufacturer filters to narrow results further. Robots without public pricing will appear at the end when sorted by price.

"Available" and "Active" mean the robot is currently sold commercially. "Pre-order" means you can reserve one but it has not shipped yet. "Development" means it is still being built. "Prototype" means it exists only as an early model. "Discontinued" means it is no longer manufactured. Use the status filter tabs above to show only robots at a specific stage.

Visit the comparison tool and select up to four robots to compare. The comparison view displays all specifications, capabilities, sensors, connectivity, and pricing in a structured side-by-side format. You can also find comparison links on individual robot pages and manufacturer pages.

We re-verify specifications against official manufacturer sources on a rolling basis. Each robot page shows a 'last verified' date. Available products are prioritized for frequent verification, and we update records whenever manufacturers announce specification changes, firmware updates, or pricing adjustments.

The database covers 9 categories spanning the full range of home and personal robotics. These include cleaning robots (vacuums, mops, window cleaners), lawn and garden robots (autonomous mowers), companion and social robots, home assistant robots, security and patrol robots, humanoid robots, quadruped robots, pool cleaning robots, and commercial service robots. Each category has a dedicated page with filtered listings and category-specific buying guidance accessible from the categories directory.

Absolutely. If you know of a home or humanoid robot that is not yet listed in our database, we welcome suggestions. Our discovery process monitors manufacturer announcements, trade shows, crowdfunding platforms, and robotics publications, but new products sometimes slip through. We evaluate each suggestion against our inclusion criteria: the robot must be a physical hardware product intended for home, personal, or commercial indoor/outdoor use, with publicly available specifications.

ui44 focuses exclusively on depth and accuracy of technical specifications rather than affiliate revenue or marketing partnerships. Every robot profile includes verified dimensions, weight, sensor arrays, connectivity protocols, capability breakdowns, component analysis, and pricing from official sources. We maintain 331 robot profiles with structured data that enables meaningful side-by-side comparisons — not just marketing copy rewritten from press releases.

Prices are displayed in the manufacturer's primary market currency — most commonly USD, EUR, JPY, or CNY. Where robots are sold in multiple markets at different prices, we list the primary market price and note regional variations on the detail page. Prices reflect the base model configuration without optional accessories or extended warranties unless noted otherwise.

The most prevalent sensors across our tracked robots include LiDAR scanners for spatial mapping, RGB cameras for visual recognition, IMU accelerometers for orientation tracking, ultrasonic proximity sensors for obstacle detection, and structured light depth cameras for three-dimensional environment understanding. Connectivity typically includes Wi-Fi for cloud connectivity, Bluetooth for local device pairing, and increasingly Matter and Thread for smart home integration. Visit the components directory for detailed breakdowns of every sensor type, actuator, and communication module used across the database, including which specific robots use each component.
