Description
- MOVE IN ANY DIRECTION — Four independently driven Mecanum wheels enable forward, backward, sideways, diagonal movement and in-place rotation. With four 520 encoder motors, the M1 provides smooth, responsive mobility for robotics development and custom autonomous projects.
- BUILT TO CARRY YOUR IDEAS — A sturdy metal-composite chassis supports payloads up to 10 kg, giving you room to add computers, LiDAR, cameras, sensors, robotic arms, cargo modules and custom hardware without starting from a lightweight toy chassis.
- CODE IT YOUR WAY — Built around an ESP32 lower-level controller with an open communication protocol and JSON commands. Connect through UART, HTTP or USB to control motion and integrate the base into your own software stack without rebuilding low-level motor control from scratch.
- BUILD BEYOND THE BASE — Designed for integration with Raspberry Pi, NVIDIA Jetson, LiDAR, depth cameras, sensors, servos and robotic arms. Add your preferred upper computer and peripherals to create vision, navigation, manipulation and custom robotics projects.
- ONE BASE, MANY POSSIBILITIES — Start with remote or programmed movement, then expand toward FPV, AI vision, SLAM navigation, mobile manipulation, delivery prototypes and ROS/ROS2 development. Documentation, protocol resources and example projects help shorten the path from idea to working robot.
Build the robot you imagine.
The XiaoR Geek OmniMatrix M1 is an open and expandable Mecanum mobile robot base designed for makers, engineering students, developers and robotics projects.
Unlike a basic robot car chassis, M1 integrates the mobility foundation needed to start building: four encoder-equipped drive motors, an ESP32 lower-level controller, onboard battery power, status display, communication interfaces and a durable platform capable of carrying up to 10 kg.
Use the M1 as a programmable mobile base on its own, or connect a Raspberry Pi, NVIDIA Jetson or other upper computer for more advanced development. Add LiDAR for mapping, cameras for computer vision, sensors for environmental awareness, a robotic arm for manipulation, or your own 3D-printed structures.
With an open communication protocol and JSON-based commands, developers can focus more on what their robot should do instead of rebuilding basic mobility control from the ground up.
Drive it. Code it. Expand it.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
- Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
- Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
- On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
