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.: 6 kg

14th 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.: 1,840 mm

53th pct in class
Repeatability How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.: 0.04 mm

43th 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.

Motion range and maximum speed per joint.

Axis	Range	Max speed
J1	-170° to 170°	220 °/s
J2	-185° to 65°	210 °/s
J3	-137° to 163°	270 °/s
J4	-185° to 185°	381 °/s
J5	-120° to 120°	311 °/s
J6	-350° to 350°	472 °/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.: 162 kg
Base footprint Length × width of the mounting base — the floor space the robot occupies.: 333.5 × 307 mm
Mounting Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).: floor, ceiling, wall, angle

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.: IP65

48th pct in class
IP rating (wrist) Ingress protection at the wrist, often higher than the body for wet/washdown duty.: IP67

14th pct in class
Operating temp Ambient temperature range for normal operation.: 0 to 55 °C

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

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-programming
ROS support Robot Operating System driver availability (none / ROS 1 / ROS 2 / both).: none
