# FANUC CR-35iB

Hardware · `CR-35iB` · verification: source checked

The CR-35iB is a six-axis collaborative robot designed to work alongside operators. It carries up to 50 kg at the wrist (35 kg standard, 50 kg with an option) and reaches a maximum of 1831 mm, with a 1643 mm operating space when the 50 kg payload mode is selected. It is driven by the FANUC R-30iB Plus controller and uses a hollow arm to reduce interference with peripheral equipment.

## Safety

- Motion speed must be set according to the risk assessment of the system.
- Collaborative Mode speed can be increased from 300 mm/s to 750 mm/s based on risk assessment.
- Operating space is restricted when the 50 kg payload mode is selected.
- The unit integrates FANUC safety sensor technology.

## Study notes

- Repeatability of ±0.03 mm is stated as based on ISO 9283.
- Motion range per axis (degrees): J1 370, J2 215, J3 338, J4 400, J5 280, J6 900.
- Maximum speed is given as 300 mm/s in Collaborative Mode and 750 mm/s in High Speed Mode.
- J4, J5 and J6 moment/inertia values are listed as 110/4, 110/4 and 60/1.5 respectively.
- Average power consumption is stated as 1 kW.
- Mechanical weight is 386 kg in the datasheet; the product page states 375 kg.
- Body protection is IP54 standard, with IP67 available for the wrist and J3 arm.
- Payload is 35 kg as standard; the 50 kg payload requires an option.
- Can be equipped with a FANUC Vision Sensor or FANUC 3D Area Sensor for object recognition.
- Programming is done via FANUC Hand Guidance or a tablet teach pendant with a drag-and-drop interface.
- The CR-35iB is not part of the CRX series.
- FANUC's product page and datasheet give different values for reach, weight. Check with FANUC before relying on it.
