FANUC
CR-4iA
Smallest robot in FANUC’s green CR collaborative line - 4 kg at 550 mm reach with 0.01 mm repeatability on a 48 kg tabletop body, mountable floor, angled or inverted so it can work above an operator without crowding the bench.

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.
- 4 kg 15th 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.
- 550 mm 2th 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 98th 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
- Wrist torque
Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.
- 8.9 N·m 18th 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.
- 2 kg·m² 65th pct in class
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° | 250 °/s |
| J2 | — | 250 °/s |
| J3 | — | 250 °/s |
| J4 | -190° to 190° | 250 °/s |
| J5 | -100° to 100° | 250 °/s |
| J6 | -360° to 360° | 250 °/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.
- 48 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor, angle, inverted
Power & controller
Electrical supply and the control cabinet that drives it.
- Power draw
Typical operating power consumption. Lower is more efficient.
- 1,000 W 5th pct in class
- Controller
The control cabinet / unit that runs the robot.
- R-30iB Plus
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
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
