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.
- 25 kg 89th 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.
- 1,800 mm 91th 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 10th 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.
- 225 °/s 51th pct in class
Motion range and maximum speed per joint.
| Axis | Range | Max speed |
|---|---|---|
| J1 | -360° to 360° | 120 °/s |
| J2 | -360° to 360° | 100 °/s |
| J3 | -360° to 360° | 150 °/s |
| J4 | -360° to 360° | 225 °/s |
| J5 | -360° to 360° | 225 °/s |
| J6 | -360° to 360° | 225 °/s |
Physical
Size, mass and how it mounts.
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor, ceiling, wall, tilted
Power & controller
Electrical supply and the control cabinet that drives it.
- Power draw
Typical operating power consumption. Lower is more efficient.
- 600 W 27th pct in class
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 5th pct in class
- IP rating (wrist)
Ingress protection at the wrist, often higher than the body for wet/washdown duty.
- IP65 17th pct in class
- Operating temp
Ambient temperature range for normal operation.
- -10 to 50 °C
- Cleanroom class
ISO 14644-1 cleanroom rating the robot is certified for. Lower number = cleaner environment.
- 5 ISO 0th 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).
- Yes
- Safety standards
Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).
- IEC 61508
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
