Introduction
"Unable to afford the ROSMASTER M3 PRO ros2 robot kit but still want to get one?" This is the most common question I receive in my inbox. Many Yahboom enthusiast budgets and university researchers' low-cost educational project cannot cover the full kit[ 1 ] in one go. Analysis of recent search data reveals that over 60% of researchers hesitate due to the $1444 price point, especially for those who already own a DOFBOT Pro or ROSMASTER M3. In this article, I will demonstrate a proven solution.What You’ll Learn in This ROS2 Robot Kit Guide:
How to combine existing DOFBOT Pro and ROSMASTER M3 hardware into a full ROSMASTER M3 Pro The 5 specific parts you'll need (with SKUs) and why the SSD requires a special system image Real validation from our engineering team—100% functional equivalence guaranteed
Real Customer Story: How a Tokyo Lab Built It on a Budget
When a customer from a Tokyo-based technology firm first asked, “Can I just mount my DOFBOT Pro onto the ROSMASTER M3 chassis to make a yahboom ros robot?”, our engineering team wasn't 100% sure. So we opened both products on the workbench.
The challenge:
The mounting holes aligned perfectly, but the standard M3 chassis lacks the specific bracket for Arm Servo #1 (P/N: 7000102005) and the correct screw sizes. Without these, the arm would not mount securely.
Our fix:
We sourced 5 specific missing parts (see table below). Most critically, the standard M3 SSD cannot be used—you must flash the ROSMASTER M3 Pro dedicated system image onto a blank SSD for the arm and LiDAR to communicate correctly. This is the software “secret sauce” that makes the yahboom ros stack work seamlessly.
The result:
