A long-reach variant of the RV-4FR, trading footprint for extra working envelope. A six-axis arm, 6 DOF, no mimic joints or closed loops.
The mechanism
Six revolute joints in series — a standard vertical-articulated arm, no mimic joints or accessory mechanisms.
About these files — read before importing
This gallery entry links directly to the official
melfa_ros2_driver
repository’s melfa_description package, unmodified — a real, literal URDF (not a xacro
template needing expansion), with visual and collision meshes for every link.
No mass or inertial data is declared anywhere in this URDF — confirmed across the whole
melfa_ros2_driver family, not unique to this model. ARMOR estimates mass for links missing
it, so the model still simulates; the numbers on this page are ARMOR’s estimate, not a real,
vendor-measured figure.
