- 7-DoF redundancy A seventh axis provides redundant degrees of freedom, letting the arm avoid obstacles and keep the end-effector oriented while working around fixtures.
- Ultra-lightweight body Body mass of about 7.8 kg supports portability and mounting on mobile bases, carts and compact workcells.
- 5 kg payload, ±0.05 mm repeatability Handles a 5 kg rated payload over a working radius of roughly 610 mm with high positional repeatability.
- Integrated controller Core control components are integrated to reduce external cabinet complexity, with multiple I/O and networking options for direct integration.
- Flexible teaching and control Supports drag/hand-guiding, teaching-pendant operation and API/JSON control for both quick setup and software-driven workflows.
- ROS-ready Robotics-software compatibility with ROS toolchains and simulation-friendly integration for research and development.
Description
The Realman Robotics RM75-B is a 7-DoF, ultra-lightweight collaborative arm with an integrated controller, designed as a standalone tabletop manipulator or as a payload on mobile robot platforms. Its seventh axis is the defining feature: the redundant degree of freedom lets the arm avoid obstacles and hold end-effector orientation while “elbowing” around fixtures. It carries a 5 kg payload with a working radius of roughly 610 mm, ±0.05 mm repeatability and an IP54-rated body weighing about 7.8 kg, running from a nominal 24 V DC supply.
The integrated-controller design keeps wiring and installation simple for mounting on AMRs, carts and compact workcells, while drag teaching, teaching-pendant operation and API/JSON control support both quick setup and software-driven integration. With ROS-based toolchains and simulation-friendly workflows, the RM75-B fits mobile manipulation, motion-planning and imitation-learning research, light industrial pick-and-place and inspection assistance.
