ROKAE Robotics continues to advance the industry with its "dual strength of rigidity and flexibility" technical philosophy through the xMate series. The xMate CR35 series not only breaks new ground with a payload capacity of 45 kg but also establishes a new technical paradigm for high-payload collaborative robots through multiple innovations.
01 Breaking Physical Limits: “Large Yet Agile”
The xMate CR35 series sets a new industry record with a maximum payload of 45 kg and a reach of 2246 mm. Despite its enhanced capabilities, the robot’s weight is 50% lighter than that of comparable industrial models. Key innovations enabling this balance of strength and flexibility include:
· Lightweight Body:
The team utilize self-developed integrated modular joints and has overcome technical challenges in integrating motors, drivers, reducers, dual-channel encoders, and sensors. Also, a modular design has been deployed that enhances overall performance, including integration efficiency and weight reduction.
· Compact Footprint:
No floor anchoring required, enabling flexible installation and rapid deployment across production lines.
· Small Control Cabinet:
Plug-and-play ready, with minimal cabling (as few as two cables between body and cabinet) for easier connectivity and setup.
· Multi-Directional Mounting:
Supports installation in any orientation (floor, ceiling, wall) with reduced rigidity requirements for mounting frames.
As payload and reach increase, so does the challenge of balancing lightweight design with rigidity. In high-acceleration, high-cycle scenarios demanding productivity, collaborative robots are prone to vibration. While many domestic solutions compromise speed or precision to mitigate this, ROKAE adopts a more advanced approach:
· Mechanical Structure Optimization:
RV reducers on axes 1 and 2 enhance rigidity by 10 times under equivalent load.
· Advanced Vibration Suppression:
Real-time vibration suppression based on multi-sensor fusion minimizes vibration and end-effector shaking across full operating speeds without sacrificing cycle time or tracking accuracy.
02 Motion Control Technology: Maximizing Hardware Performance
Traditional collaborative robots often sacrifice speed for safety. However, customers, especially those familiar with industrial robots, expect collaborative models to maintain their inherent advantages while improving cycle times and efficiency.
The xMate CR35 series leverages two core technologies, OptiMotion and TrueMotion, to deliver industrial-grade motion performance within a safe collaborative framework:
· Repeat positioning accuracy: ±0.05 mm
· Maximum tool center point speed: ≤6 m/s
· Axis speed increase: 20%
These technologies also prevent component overuse, ensuring long-term reliability.
· OptiMotion:
Based on high-precision dynamic modeling and parameter identification, it enables optimal planning using full dynamic models, increasing path speed by 20% while ensuring the robot operates at its performance limits.
· TrueMotion:
Integrates speed-independent path planning, high-precision error compensation, and inertia feedforward technology. This ensures consistent path accuracy (<1 mm) across varying speeds, delivering "what-you-see-is-what-you-get" performance.
· Dynamic Parameter Modeling:
Maximizes motor performance while extending the lifespan of critical components (e.g., motors, reducers) by 30%, preventing premature wear and reducing maintenance costs.
03 Reimagined Safety Systems: Multi-Layer Protection
Industry-Leading Safety Features
· SIL3-Rated Independent Safety Controller:
The standalone control cabinet offers enhanced I/O resources and greater scalability. Equipped with a built-in safety controller certified by TüV, it complies with ISO 13849-1:2015 functional safety standards, achieving Performance Level (PL) d, Category 3.
· Dual-Redundant Safety Architecture:
Dual absolute encoders and dual-channel sensors monitor robot data in real time, eliminating safety risks caused by sensor or controller failures.
· 21 TüV Functional Safety Certifications:
Fully meets the safety certification requirements for human-robot collaboration specified in ISO 15066.
· Magnetic Friction Brake:
Reduces braking distance by 80% compared to traditional pin-type brakes, effectively responding to emergencies and preventing payload drops during power loss.
Intelligent Protection
· Multi-Level Safety Zones:
Users can define custom safety zones (e.g., deceleration zone 1&2, stop zone). The robot triggers pre-set safety actions when entering or exiting these zones.
· Workspace Protection:
Virtual walls can be set for joints or end-effectors, ensuring the robot operates within user-defined limits.
· Collision Safety Protection:
A collision detection algorithm based on fine-grained dynamic models monitors external forces in real time, initiating immediate stops or retreats to protect the robot, equipment, and personnel.
04 Enhanced Usability: Lowering the Barrier to Use
· Graphical Programming:
An intuitive, wizard-based interface for parameter setting and programming reduces complexity, enabling operators without specialized expertise to get started quickly.
· Rich Process Packages:
Supports palletizing, photovoltaic, tray loading, and other process-specific packages:
- Palletizing Package: Includes pre-configured solutions; users can quickly set up and run tasks via graphical guidance, with automatic stack generation and path planning based on product and tray dimensions.
- Photovoltaic Package: Supports insertion, layout, and handling processes, simplifying operation for end-users and enabling batch deployment.
-Tray Loading Package: Automatically generates workpiece position data and simplifies programming for tray-based scenarios with dedicated commands.
The xMate CR35 series exemplifies ROKAE’s commitment to innovation—combining high payload, precision, safety, and ease of use to meet the evolving demands of modern industrial applications.
