Micro-class precision (±0.02 mm)
Thanks to TrueMotion algorithms and a rigid design, the CR3A achieves repeatability of up to ±0.02 mm. This is the highest result in the series, ideal for tasks requiring surgical precision, such as electronics assembly, adhesive dispensing, or parts testing.
Higher efficiency and vibration reduction
The CRA series reduces cycle times by 25%, allowing for operation at speeds up to 3 m/s. An innovative vibration dampening system reduces vibrations by 50% during sudden stops, ensuring smooth operation and protecting delicate parts and grippers from wear.
Compact and secure collaboration
The arm weighs just 16.5 kg and takes up minimal space, making it ideal for desktop applications. The collision detection system responds in less than 1 ms, allowing for safe operation alongside people without cages or protective fencing.

Architecture and key technological advantages of the DOBOT CR3A
Application and Kinematics
A comprehensive operational profile for demanding industries
With the safety, performance, flexibility, and ease of use of the CR Series, the CR3A exceeds the 3 kg payload limit , opening up a wider range of applications for collaborative robots. With a working radius of 620 mm, the CR3A can meet the demands of heavy picking, packaging, palletizing, and welding in the automotive, appliance, logistics, and metal processing industries.
Implementation and Hardware
User-friendly design for faster implementation
The DOBOT CR3A utilizes the industry's first integrated dual-channel end effector that can directly connect to multiple end-effectors. It also features visual status indicators at the base and head, allowing intuitive recognition of the device's operating status directly at the workstation.
Traffic Control
Maximum stability and 50% reduction in residual vibrations
While the advanced CRA series allows for scalable payloads for heavy-duty applications, the CR3A offers ultra-compact maneuverability – 3 kg payload with 620 mm of reach . Thanks to an advanced motion control algorithm, the robot operates more stably, and residual vibration is reduced by 50% during quick emergency stops, preventing damage to delicate components.
Integration and PLC
24 digital IO ports for unlimited flexibility
The CR3A robot supports Profinet and Ethernet/IP communication protocols and seamlessly connects to a PLC. It features 24 digital IO ports with industry-leading PNP and NPN switching support , making it easy to expand applications with additional actuator peripherals, grippers, or advanced vision sensor systems.
Occupational health and safety
High level of protection for safer collaboration
Both the robot body and control box achieve a high IP54 protection level . In the event of an overload, the robot will automatically sound an alarm. The CRA is also equipped with innovative electromagnetic brake protection , which reduces the drop distance of the end tool in the event of a power failure, ensuring complete personnel safety.
