Full specifications

Performance

How much it lifts, how far it reaches, how precisely it repeats.

Payload Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.: 30 kg

55th pct in class
Reach Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.: 2,700 mm

75th pct in class
Repeatability How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.: 0.05 mm

31th pct in class
Axes (DOF) Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.: 6

Motion range & speed

Per-axis travel limits and rotational speeds.

Max axis speed Highest rotational speed of the fastest joint. Higher helps short, fast moves.: 407 °/s

41th pct in class

Axis	Range	Max speed
J1	-180° to 180°	172 °/s
J2	-90° to 135°	134 °/s
J3	-185° to 80°	186 °/s
J4	-200° to 200°	255 °/s
J5	-130° to 130°	330 °/s
J6	-360° to 360°	407 °/s

Physical

Size, mass and how it mounts.

Robot weight Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.: 525 kg
Mounting Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).: floor, ceiling

Environment

Conditions it can operate in — dust, water, temperature, cleanliness.

IP rating (arm) Ingress protection of the body against dust/water (IEC 60529). First digit = dust, second = water. Higher resists harsher environments.: IP54

19th pct in class

Safety

Standards met and collaborative-operation capability.

Collaborative Whether the robot is designed to work safely next to people without fencing (power-and-force-limited).: No
Safety standards Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).: ISO 10218-1

Control & software

Programming, languages and ecosystem.

Programming How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.: teach-pendant, offline-sim
ROS support Robot Operating System driver availability (none / ROS 1 / ROS 2 / both).: none
