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.: 500 kg

93th 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.: 2,525 mm

68th pct in class
Repeatability How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.: 0.1 mm

4th 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
Wrist torque Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.: 3,010 N·m

89th pct in class
Wrist inertia Allowable moment of inertia at the wrist — how much rotating mass it can swing without overload. Higher is more capable.: 510 kg·m²

93th pct in class

Motion range & speed

Per-axis travel limits and rotational speeds.

Motion range and maximum speed per joint.

Axis	Range	Max speed
J1	-180° to 180°	75 °/s
J2	-90° to 50°	65 °/s
J3	-70° to 165°	65 °/s
J4	-360° to 360°	100 °/s
J5	-120° to 120°	100 °/s
J6	-360° to 360°	160 °/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.: 2,450 kg
Mounting Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).: floor

Environment

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

IP rating (wrist) Ingress protection at the wrist, often higher than the body for wet/washdown duty.: IP67

14th 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

Safety certifications

ISO 10218-1 — the primary industrial-robot safety standard covering design and construction requirements
