DOBOT CR20A OVERVIEW
The Dobot CR20A, with a 20 kg payload and 1700 mm reach, is a 6-axis arm designed to handle heavy-duty tasks in industrial environments.
The CR20A is designed for the most demanding collaborative tasks, such as palletizing, welding, and heavy material handling. At 73 kg with a 2 m/s max TCP (Tool Center Point) speed, it's built to move real industrial loads without giving up the safety features to work alongside people and ease of deployment that define the CRA line.
HOW DOES DOBOT CR20A WORK?
The CR20A uses Dobot's integrated joint design and EtherCAT bus communication to coordinate all 6 axes with millisecond-level response time to enable controlled and stable motion even under heavy load.
It has an industry-first dual-channel end-effector design that allows CRA20 to plug directly into multiple end tools, and a visual status indicator at the base that gives an at-a-glance read on operating state.
Built-in force and collision-detection sensors continuously monitor for unexpected contact, automatically slowing or stopping the arm if it senses an obstacle or person nearby, allowing the CR20A cobot to run without a safety cage even at 20kg payload class.
APPLICATIONS OF DOBOT CR20A:
- Palletizing: Stacking and organizing heavy goods across large work areas
- Welding: Automotive and metal-processing welding tasks
- Machine Loading & Unloading: Feeding CNC machines, presses, and heavy production equipment
- Material Handling & Transportation: Moving heavy components between different stations
- Packaging & Case Handling: End-of-line packaging for bulkier products
- Quality Inspection: Camera-guided inspection of large parts and assemblies
DOBOT CR20A FEATURES
- High Payload for Heavy-Duty Work: 20 kg payload and 1700 mm reach, suited to large parts, long-reach workspaces, and multi-station layouts
- Safe Human-Robot Collaboration: 22 built-in safety functions including 5-level adjustable collision detection
- Stable at High Load: Advanced motion control algorithm reduces residual vibration by 50% during high-speed emergency stops
- Multiple Easy Programming Ways: DobotStudio Pro graphical interface, Blockly block programming, Lua scripting, Python SDK, and drag-to-teach plus control from smartphone, tablet, or PC
- Built For Integration: Supports 2 end-effectors and EtherCAT, Modbus TCP, Profinet, EtherNet/IP, and Wi-Fi, with 24 digital I/O ports supporting both PNP and NPN switching
- Fast Deployment: Roughly 20 minutes to install and typically operational within an hour
- Dedicated Robot Control Cabinet (CC263): The CR20A comes with a control cabinet for managing power, communication, and I/O for the connected robot arm
- 1-Year InDro Warranty & Support
DOBOT CR20A VARIATIONS:
The Dobot CR10A comes in 4 versions to meet certain requirements:
- Dobot CR20A - The main version.
- Dobot CR20AP (CR20A-IP68) - Built for harsh environments with dust, humidity, water mist, or oil contamination. Great for washdown or heavy-contamination settings.
- Dobot CR20AF (Force-Controlled model) - Adds a high-precision integrated 6-axis force sensor at the flange, enabling compliant force control for tasks like grinding, polishing, and precision assembly. Holds constant contact force for surface-tracking work and detects collisions as small as 1 N.
