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.
- 3 kg 4th 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.
- 620 mm 8th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.02 mm 74th 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
- Max TCP speed
Top linear speed of the tool centre point. Higher means faster cycle times.
- 3,000 mm/s 73th pct in class

| J6 | -360° to 360° | — |
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.
- 17 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor, ceiling, wall, any
Power & controller
Electrical supply and the control cabinet that drives it.
- Power draw
Typical operating power consumption. Lower is more efficient.
- 120 W 97th 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
- Operating temp
Ambient temperature range for normal operation.
- 0 to 50 °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).
- Yes
- Safety standards
Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).
- ISO 13849-1:2015 PLd Cat.3, ISO 10218-1:2011, ISO/TS 15066, CE, UL
- Cert. cobot payload
Payload at which collaborative (force-limited) operation is still certified.
- 3 kg 3th pct in class
Control & software
Programming, languages and ecosystem.
- Programming
How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.
- hand-guiding, graphical, teach-pendant
- Languages
Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).
- Blockly, LUA
- ROS support
Robot Operating System driver availability (none / ROS 1 / ROS 2 / both).
- ros1
- Teach pendant
The handheld programming/jog device supplied.
- 10.1-inch HD capacitive, 1920x1280
- Offline programming
Whether programs can be built and validated offline in a digital twin before deployment.
- Yes
Connectivity & I/O
Signals, fieldbuses and tooling interfaces.
- Fieldbus
Industrial networks supported for PLC/cell integration (PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, CC-Link, etc.).
- Modbus TCP, Modbus RTU, EtherNet/IP, PROFINET
- Integrated vision
Whether a camera / vision system is built into the robot or controller.
- No
