Dobot CR5AF Force-Control Collaborative Robot (CRAF Series)
The Dobot CR5AF is a next-generation 6-axis collaborative robot from the CRAF series, designed for advanced industrial applications requiring precise force control, adaptive compliance, and high-level human-robot interaction. Built on the CRA platform, it integrates a high-resolution 6-axis force sensor directly into the flange, enabling intelligent force-based automation.
With a 5 kg payload capacity and a compact 900 mm working reach class, the CR5AF is optimized for precision-driven processes such as grinding, polishing, complex assembly, and medical automation tasks.

Advanced Force-Control Technology
The CR5AF introduces intelligent force control that enables the robot to maintain constant contact force during operations. This is essential for applications requiring consistent pressure, such as polishing, grinding, or precision assembly.
The integrated flange sensor allows the robot to detect even minimal force changes, enabling highly responsive and adaptive motion control.
Intuitive Teaching and Operation
With ultra-low resistance (below 2 N drag force), operators can guide the robot effortlessly using direct physical interaction. The entire flange acts as an active teaching surface, allowing highly intuitive path programming.
Orientation-locked dragging enables precise trajectory definition, improving repeatability and process accuracy in complex workflows.
Environmental Awareness and Adaptation
The CR5AF features real-time environmental sensing capabilities, allowing it to detect variations such as surface height changes or irregular geometries. Based on this feedback, the robot dynamically adjusts its motion for optimal process execution.
Typical Applications
Precision assembly with force feedback
Surface grinding and polishing
Automotive finishing processes
Welding with force compliance
Medical device automation
Adaptive loading and unloading
Complex contact-based manufacturing tasks
Safe Human-Robot Collaboration
The CR5AF is designed for safe interaction in shared workspaces. Its force-sensing system enables collision detection with sensitivity down to 1 N, significantly reducing potential impact forces during unexpected contact.
At the same time, the system is engineered to withstand high operational stress, with an impact resistance of up to 2000 N, ensuring reliability in demanding industrial environments.
System Integration and Design
The robot includes a ring status light on the flange for real-time state visualization and a dedicated drag interface for simplified teaching workflows. Importantly, the design does not occupy tool-side RS485 or I/O ports, ensuring full compatibility with external devices such as grippers or vision systems.
Its plug-and-play architecture allows rapid deployment in existing automation lines without extensive configuration effort.
