Dobot Unveils Brand New CRA Series Collaborative Robots At Automate Show

#Company · May 24, 2023

Dobot’s brand new CRA Series collaborative robots and the CRV500 Smart Camera were officially launched at the Automate Show. The new cobots incorporate high performance harmonic drive reducers and electromagnetic brakes, alongside updated software with redesigned user interface. Compared to its predecessor, the CRA Series has noticeable performance boost, and is more efficient, safer and easier to use. The CRV500 Smart Camera leverages Dobot’s self-developed 2.5D spatial compensation technology, allowing equipped robots to grab tilted or inclined objects with higher precision, opening doors to a variety of vision-based automation scenarios.



With the rapid expansion of cobot application scenarios, the market today seeks high performance robots. Dobot has always been exploring the optimal human machine collaborative solution, building more than 20 robot models to target different use cases and industries. The high performance CRA Series aims to satisfy the most demanding users to accelerate their transition to automated solutions to increase their production gains.


CRA Series: New Architecture for Better Performance.


Higher efficiency: Self-developed highly integrated joints with high performance harmonic drive reducers to improve cycle time by 25%.



Greater accuracy: Optimized precision control algorithm to greatly reduce vibrations. Up to ±0.02 mm repeatability and 0.2 to 0.4 mm trajectory accuracy during complex motion.


Much safer: Electromagnetic brakes auto-engage in 18 ms at power outage to restrict robotic arm falls less than 1 mm, effectively prevent end tool from dropping. The CRA Series also has built-in virtual boundaries, real-time payload detection and other safety features to ensure the safety of nearby workers.


Easier to use: The brand new operating software is more user-friendly to operate. It supports graphical programming, scripting and drag-to-teach for trajectory replay It is multi-platform and works with personal computers, tablets and smartphones and more.


More reliable: The control box is 25% smaller with optional IP54 protection. It can withstand harsh environments to help lower maintenance costs.


The CRA Series supports Modbus, Ethernet/IP and Profinet communication, connecting with PLC and other automation system seamlessly. With 24 I/O ports available and PNP/NPN switching, expansion can be carried out more easily.


CRV 500 Smart Camera: Accurate Grabbing with Self-developed Algorithm.


At the exhibition, Dobot also launched another new product, the CRV500 smart camera. With Dobot’s self-developed 2.5D spatial compensation technology, it can be used with the CRA and CR Series collaborative robots to enable accurate identification of objects’ horizontal angle and inclination for accurate grabbing.



The CRA Series released this time has 7 robot models with 3 kg, 5 kg, 7 kg, 10 kg, 12 kg, 16 kg and 20 kg payloads, and working radius from 620 to 1,700 mm, covering various industries including consumer electronics, semiconductor, automotive, renewable energy, metal processing, logistics, healthcare, retail and more. It is also capable of dozens of high precision application such as pick and place, sorting, screwdriving, inspection, gluing, welding, transportation, polishing, and palletizing, covering high payloads and big areas scenarios.


Dobot has developed specialized process packages software to simplify automation deployment of complex processes including screwdriving, welding and palletizing. With this software, users can quickly setup the automation processes without writing a line of code.


The 3 kg, 5 kg and 10 kg payload models in the CRA Series are compatible with the DOBOT SafeSkin for safer human-machine collaboration. The SafeSkin is Dobot’s exclusive, self-developed non-contact pre-collision detection solution which can sense obstacles coming within 15 cm and stop before colliding, effectively increases the safety and efficiency for human-machine collaboration.
