Unmatched compliance and precision
All-in-one force control, Plug and Play
The CRAF series is based on the CRA series and integrates a high-precision 6-axis force sensor at the flange, giving the cobot enhanced compliant force control and precise operation.
Atloks ar gredzena statusa indikatoru
Equipped with a ring status indicator for real-time visibility of the robot status. Designed with a button for press-and-drag teaching.
Non-occupying end interface
Does not occupy the tool-side RS485 or I/O ports, ensuring compatibility with external devices (such as electric grippers or the VX500 smart camera).
Ideal for a wide range of applications
Assembly
Users can constrain the orientation for precise trajectory programming.
Welding
With an ultra-low drag start force (<2 N), the CRAF robot can be guided effortlessly, even with just a drinking straw, enabling millimetre-precise drag teaching and 0.1 mm point-to-point accuracy.
Polishing
The CRAF robot maintains constant force with automatic compensation, ensuring flawless performance in high-precision applications such as automotive grinding and polishing.
Healthcare
The robot perceives its external environment in real time (for example, detecting changes in table height) with automatic surface scanning, enabling adaptive motion control for precise task execution based on environmental feedback.
Other collaborative scenarios
With integrated force-sensing collision detection (sensitivity down to 1 N), the CRAF robot greatly reduces collision forces while achieving industry-leading 2000 N impact resistance, safely handling frequent operational impacts and interference collisions in real-world applications.
