What makes it work
DOBOT CR20AP
The most powerful IP68 collaborative robot in the CRA-IP68 series — 20 kg payload and 1300 mm reach with full-body waterproof protection, oil-resistant fluororubber exterior, and internal pressurisation for the most demanding harsh environments.
Maximum-Payload IP68 Robot Built for the Harshest Environments
The DOBOT CR20AP is specifically designed for tough working environments with high dust, high humidity, and high oil contamination. It retains the excellent performance, functionality, and ease of use that the CRA series is celebrated for — while its enhanced IP68 protection further improves adaptability and reliability in challenging conditions. Certified by SGS under IEC 60529, the robot passed a rigorous 72-hour test to meet IP68 waterproof standards. With a 20 kg payload, 1300 mm working radius, ±0.02 mm repeatability, and 2 m/s maximum linear speed, the CR20AP is the highest-capacity CRA-IP68 model — bringing maximum-payload IP68 capability to food and beverage, pharmaceutical, metalworking, and other industries where frequent washdown, exposure to cutting fluids, or high-humidity operation is standard. It supports drag-to-teach control, graphical programming, and code-based programming — no specialist required.
Built Around Four Principles
Stand Out in Complicated, Harsh Environments
Full IP68 Waterproof Design, Ready to Master
The CR20AP achieves full IP68 waterproof protection across the entire robot body — certified by SGS under IEC 60529 after a rigorous 72-hour test. This makes it fully capable of handling high-humidity environments, water mist exposure, and frequent washdown cycles that would compromise a standard collaborative robot. With a 20 kg payload and 1300 mm working radius, the CR20AP brings the highest-capacity IP68 protection to food processing, pharmaceutical production, and metalworking cells with coolant spray — maintaining full operational integrity at maximum load throughout every production shift.
Anti-Dust Design for Cutting and Grinding
The CR20AP's sealed body handles high-dust environments directly, making it well suited for cutting and grinding applications where fine particles would otherwise penetrate joints and degrade performance in standard robots. The full-body sealing prevents particulate ingress at every joint and cable entry point, keeping internal components clean and ensuring consistent ±0.02 mm repeatability across long production runs in abrasive environments — even at the 20 kg payload level.
Oil Resistant — Perfect for Cutting Fluid
All exterior plastic components on the CR20AP are manufactured from fluororubber — a material known for its exceptional chemical stability and strong corrosion resistance. This makes the robot highly resistant to cutting fluids, lubricants, oils, and other chemical agents present in metalworking and manufacturing environments. Where standard cobot housings degrade under repeated oil exposure, the CR20AP's fluororubber exterior retains its structural and sealing integrity across the full service life of the robot.
Internal Pneumatic System
The CR20AP incorporates a built-in internal pneumatic system that enables internal pressurisation of the robot body. This positive-pressure design actively enhances the cobot's sealing capabilities by preventing contaminants — dust, moisture, oil mist — from entering through joints and cable passages during operation. Unlike passive sealing alone, the internal pressurisation provides an active barrier that maintains protection levels even during dynamic movement across the robot's full working envelope.
IP54 Waterproof Control Cabinet
To complement the IP68 robot body, the CR20AP's control cabinet (CC262) carries an IP54 waterproof rating — providing dust and splash protection for the controller electronics in harsh production environments. Available in both AC Edition (Standard) and DC Edition (Mobile), the control cabinet is designed to operate safely alongside the robot in the same demanding conditions. This complete system protection makes the CR20AP deployable in environments where both the robot and its control infrastructure are exposed to contamination.
Perfect for High Humidity, Dusty, Water Mist Conditions
The CR20AP is purpose-built for operating environments that combine multiple contamination challenges simultaneously — high humidity, airborne dust, and water mist. Industries such as food and beverage, pharmaceuticals, chemical processing, and wet metalworking require robots that can be cleaned in place and withstand condensation, steam, and liquid spray without downtime or degradation. The CR20AP handles these conditions at full 20 kg payload capacity — the highest in the CRA-IP68 series. Note: while IP68 rated, the CR20AP is not suitable for prolonged underwater use.

Common Questions About the CR20AP
What IP rating does the DOBOT CR20AP have?
The CR20AP robot body carries an IP68 waterproof rating — certified by SGS under IEC 60529 after a rigorous 72-hour test. The control cabinet (CC262) carries an IP54 rating. IP68 means the robot body is protected against dust ingress and against prolonged immersion in water, making it suitable for washdown, water mist, and high-humidity environments. Note that while IP68 rated, the CR20AP is not designed for prolonged underwater use.
What makes the CR20AP different from the standard CR20A?
The CR20AP is built on the CR20A platform but adds full IP68 waterproof protection across the robot body, oil-resistant fluororubber exterior components, and an internal pneumatic pressurisation system for active sealing. The standard CR20A carries only IP54 protection. The CR20AP is designed specifically for harsh environments — food and beverage, pharmaceuticals, metalworking with cutting fluids, and other applications requiring frequent cleaning or exposure to liquids, dust, or oils. Performance specs including payload, reach, speed, and repeatability remain identical to the CR20A.
What is the internal pneumatic system on the CR20AP?
The CR20AP includes a built-in internal pneumatic system that enables positive internal pressurisation of the robot body. By maintaining higher pressure inside than outside, this system actively prevents dust, moisture, oil mist, and other contaminants from entering through joints and cable passages during robot operation. This active sealing mechanism works alongside the passive IP68 sealing to provide comprehensive contamination protection at the full 20 kg payload level.
Which industries is the CR20AP suited for?
The CR20AP is particularly well suited for food and beverage production (where washdown with high-pressure water is routine), pharmaceuticals (clean room and wet environments), metalworking (cutting fluid and oil mist exposure), and any other industry where robots must handle the heaviest components while operating in high-humidity, high-dust, or chemically contaminated environments. Its 20 kg payload capacity — the highest in the CRA-IP68 series — combined with its IP68 body and fluororubber exterior make it the most capable long-term solution in these conditions.
What installation orientation does the CR20AP support?
The DOBOT CR20AP supports upright installation only. This should be factored into workcell design. The control cabinet (CC262) is available in AC Edition for standard grid power and DC Edition for mobile or alternative power configurations.
