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.

4 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.

400 mm
6th pct in class
Repeatability

How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.

0.01 mm
54th 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.

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.

IP20

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).
