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.

20 kg
78th 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.

1,831 mm
33th pct in class
Repeatability

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

0.03 mm
44th 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.

2,000 mm/s
Wrist torque

Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.

22 N·m
17th 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.

0.65 kg·m²

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.

720 °/s
50th pct in class

Motion range and maximum speed per joint.

Axis Range Max speed
J1 -170° to 170° 210 °/s
J2 -100° to 160° 210 °/s
J3 -190° to 268.4° 265 °/s
J4 -200° to 200° 420 °/s
J5 -180° to 180° 420 °/s
J6 -450° to 450° 720 °/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.

250 kg
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 supply

Required input voltage / phase for the controller.

3-phase 200VAC
Power draw

Typical operating power consumption. Lower is more efficient.

1,500 W
25th pct in class
Controller

The control cabinet / unit that runs the robot.

R-30iB Plus

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.

IP67
86th pct in class
IP rating (wrist)

Ingress protection at the wrist, often higher than the body for wet/washdown duty.

IP67
38th pct in class
Operating temp

Ambient temperature range for normal operation.

0 to 45 °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
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
Languages

Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).

KAREL, TP
Teach pendant

The handheld programming/jog device supplied.

iPendant Touch
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.).
