- Long reach, lightweight build A 900 mm working radius at roughly 10 kg body weight supports portable workcells and mobile manipulation where heavier arms are hard to mount.
- Integrated base controller The controller is built into the bottom of the arm, simplifying wiring and physical layout in compact and mobile deployments.
- Broad connectivity Wi-Fi, Ethernet, Bluetooth, USB serial, and RS485 support integration from direct machine control to orchestration via PCs or edge gateways.
- Multiple teaching and control modes Drag (hand-guiding) teaching, a teaching pendant, and API/JSON control bridge fast setup with repeatable production sequences.
- Precise, repeatable positioning Delivers ±0.05 mm repeatability across 6 degrees of freedom for light assembly, inspection, and lab-handling tasks.
- Documented durability Realman lists a 30,000-hour continuous service life under rated load, with MTBF testing certification from the Shanghai National Robot Testing Center.
Description
The Realman RML63-B is the basic-version, long-reach model in the RML Series, built for scenarios where reach, portability, and software integration matter more than high payload. It pairs a 900 mm working radius with a 3 kg rated payload and ±0.05 mm repeatability across a 6-DoF platform, while the aluminium-alloy structure and modular joint design keep body weight to roughly 10 kg. A controller integrated at the base of the arm simplifies the physical layout, and multiple communication options — Wi-Fi, Ethernet, Bluetooth, USB serial, and RS485 — support everything from direct machine control to higher-level orchestration via PCs or edge gateways.
The RML63-B is commonly positioned for laboratory and medical workflows such as sample movement, tube handling, and tray transfers; service and commercial automation prototypes; education and R&D including embodied-AI and manipulation research; and light assembly and vision-guided inspection within a 3 kg envelope. Operators can teach the arm by hand-guiding, use a teaching pendant, or drive it programmatically through API/JSON, bridging fast setup with repeatable production logic. Powered from a 24 V DC supply with an IP54-rated body, and with published references such as a 30,000-hour continuous service life under rated load, it supports portable workcells and mobile-manipulation concepts that heavier industrial arms cannot easily accommodate.

Frequently Asked Questions
The RML63-B is the basic-version, long-reach robotic arm in Realman's RML Series. It offers 6 degrees of freedom, a 900 mm working radius, a 3 kg rated payload, and ±0.05 mm repeatability in a lightweight aluminium-alloy body of about 10 kg.
It is commonly used for laboratory and medical workflows such as sample movement and tray transfers, service and commercial automation prototypes, education and R&D including embodied-AI research, and light assembly and vision-guided inspection within a 3 kg payload.
The RML63-B is the basic version without built-in force sensing and lists a 900 mm working radius. The RML63-6F adds integrated six-axis force/torque sensing for compliant, contact-rich tasks and lists a slightly longer 928.5 mm radius; both share the same 6-DoF, 3 kg-payload platform.
