robotindex Yahboom ROSMASTER
A family of ROS/ROS2 educational and research robot kits from Yahboom, spanning eight active models — from the $300 Ackermann-steered A1 up to the $1,400+ M3 Pro with a 6-DOF arm and dual lidar. This catalog entry represents the whole ROSMASTER line as one product family rather than eight separate pages; the photo shown is specifically the base ROSMASTER X3, a mecanum-drive SLAM/navigation kit.

Lineup

Arm Option
6-DOF, 2 SKUs onlyX3 Plus and M3 Pro add a robotic arm; base X3/M3 do not
Price Range
$300 – $2,000+A1 cheapest; M3 Pro's top configuration most expensive
Reference Price
Pricing spans the widest range of any single entry in this catalog, because it covers eight distinct SKUs: ROSMASTER A1 from $299.90, M1 from $349.90, R2 around $655, X3 around $659, M3 from $779.90 (list $1,809.90), X3 Plus from $1,229 (list $1,729), and M3 Pro from $1,444 (list $2,034) — with R2L positioned as a stripped-down, lower-cost variant of R2 not separately listed at a fixed price. Sold through Yahboom's own storefront (category.yahboom.net, primary source for current pricing), RobotShop, Amazon, and AliExpress, with per-model pricing that swings further depending on which compute board (Raspberry Pi 5 vs. a top-tier Jetson Orin NX Super module) is selected at checkout.
Insights
Each ROSMASTER model has a real, actively-starred GitHub repository under Yahboom's official organization, but license files are not clearly present in these repos, so this entry is not tagged open source — the code is public but not formally licensed.
Firmware & Community
YahboomTechnology/ROSMASTERX3
Yahboom's official GitHub repo for ROSMASTER X3 has real Nav2/Cartographer code with meaningful community activity (~99 stars), though it carries no LICENSE file, so usage rights are not formally granted.
Verified against Yahboom's official ROSMASTER collection page and individual product pages for A1, M1, R2, R2L, X3, X3 Plus, M3, and M3 Pro; the YahboomTechnology GitHub organization and per-model repositories (including star/fork counts and Nav2/Cartographer configuration files); DOFBOT's separate official product page and GitHub repo (confirming it is not part of the ROSMASTER line); independent educator AutomaticAddison's public Nav2 tutorial repo built on a physical ROSMASTER X3; a university robotics club's (AIRclub-UdeSA) public coursework repos; a hobbyist-robotics forum thread discussing Yahboom's documentation and support quality; and RobotShop and OpenELAB distributor/education listings. Flagged as uncertain: R2L's exact standalone price (not separately listed at research time); precise top-configuration pricing for X3 Plus and M3 Pro once every compute-board option is factored in; and whether any ROSMASTER repository carries a formal open-source license, which this catalog could not confirm from the repos' visible files.
