Product Description

The DOBOT CR Series is a family of lightweight, 6-axis collaborative robots (cobots) designed for safe human-robot collaboration across a wide range of industrial applications. They feature a lightweight design with a compact footprint, enabling flexible deployment in space-constrained environments.

With built-in safety features including 22 safety functions and ISO 13849 / TS15066 certification, the CR Series ensures safe operation in collaborative settings. An optional SafeSkin non-contact proximity sensor can detect obstacles within 15 cm, enabling "stop-before-collision" functionality for enhanced safety.

FAQ

Q1: What is the difference between the CR3, CR5, CR10, CR16, and CR20A models?

The main differences are payload capacity and working radius:

CR3: Lightweight (3 kg payload, 620 mm radius) – ideal for 3C assembly, small workstations, new retail

CR5: Versatile mid-range (5 kg, 900 mm) – good balance of reach and payload

CR10: Large reach (10 kg, 1300 mm) – suitable for wider workspaces with speeds up to 4 m/s

CR16: Heavy-duty (16 kg, 1000 mm) – for machine tending and palletizing

CR20A: High-payload (20 kg, 1700 mm) – for heavy handling and large workspace applications

Q2: What is SafeSkin and how does it work?

SafeSkin is an optional non-contact proximity sensor system wrapped around the robot's forearm and J4-J6 joints. It detects obstacles (human body, metal, liquid) within 5–15 cm and triggers a stop-before-collision response within 0.01 seconds, enhancing safety without physical barriers.

Q3: What is the repeatability of the CR series?

CR3 & CR5: ±0.02 mm

CR10 & CR16: ±0.03 mm

CR20A: ±0.05 mm

Q4: What communication protocols are supported?

Standard: TCP/IP, Modbus TCP, Modbus RTU (RS485), and Wi-Fi. Optional: PROFINET and EtherNet/IP for integration with industrial automation systems.

Q5: Can the robot be mounted in different orientations?

Yes. Models support floor, wall (side), and ceiling (inverted) mounting for flexible deployment in various layouts.

Q6: What safety certifications does the CR series hold?

The CR series is certified with CE, CR, FCC, KCs, RCM, UL, ISO 13849, and TS15066.

Q7: Can the CR series be integrated with AGVs?

Yes. CR series robots can be mounted on AGVs for mobile composite robot applications. Communication is typically via Modbus (master/slave) with the AGV's control system.
