UR robots have emerged as the world’s leading collaborative robots, underpinned by their core strengths of flexible deployment and user-friendly operation. Our KWR series force sensors deliver high precision and fast dynamic response. When paired with UR robots and UR Caps plugins, they enable customers to accelerate functional development.
While the Polyscope platform of UR robot series supports plugin expansion, we have identified several prominent pain points users encounter during force-controlled operations. First, most alternative solutions fail to access UR’s native force control interfaces, resulting in poor compatibility and preventing reuse of the robot’s built-in process packages. Second, hardware integration is cumbersome, with pinch point hazards during installation that violate collaborative robot safety standards. Third, insufficient communication real-time performance limits both data accuracy and response speed of the sensors.
To address these pain points, we have developed an exclusive UR Cap plugin with deep native compatibility for UR’s architecture. The standout feature of this plugin is its ability to directly replace the built-in sensors of UR robots with Kunwei KWR series 6-axis force sensors boasting faster response and superior precision. Crucially, it retains full functionality of all native UR built-in process packages including hand guiding and force-guided searching. It is ready for immediate use out of the box with no secondary development required — a capability unmatched by most competing solutions on the market.
We will now walk through the robust hardware and communication capabilities of this product suite. In terms of hardware, the sensor’s form factor perfectly matches the end effector of UR robots, eliminating pinch point risks post-installation and fully complying with collaborative robot safety standards. Electrically, it connects directly to the robot’s quick-disconnect end effector port. A single cable handles both power supply and data communication, natively supporting UR’s 1 Mbps baud rate for ultra-low-latency data transmission, laying a solid foundation for high-precision force control.
The product suite features a streamlined composition consisting solely of the UR Cap plugin and one dedicated connection cable, delivering true plug-and-play functionality.
Our native force control solution — combining UR robots, KWR 6-axis force sensors and the exclusive plugin — serves both industrial and cutting-edge application sectors. Industrial use cases include active force-controlled grinding, precision assembly, constant force regulation and automatic tolerance compensation, which drastically boost production yield rates. For advanced research fields, it supports dual-arm collaborative force control, embodied intelligence, medical research and more. Moving forward, we can collaborate with customers to co-develop customized industry-specific process packages and continuously expand application coverage.
Installation of the plugin is highly straightforward:
- Complete hardware connection: Mount the sensor directly onto the robot end effector with pinch-point-free safe installation.
- Import the UR Cap plugin; one-click configuration requires no coding.
- Attach the dedicated cable to enable simultaneous power delivery and data communication. Native hand guiding and all application functions activate instantly without robot reboot.
To conclude, we summarize the five core advantages of this product solution:
- Deep native compatibility with full support for all UR native force control process packages.
- Safety-compliant hardware design with pinch-point-free installation, meeting collaborative robot safety criteria.
- High-speed real-time communication enabled by 1 Mbps baud rate for rapid force control feedback.
- Comprehensive performance upgrades featuring faster sensor response and enhanced measurement precision.
- Extensible ecosystem with options for joint development of industry-exclusive process packages in the future.
