Overview
The Kassow KR810 is the mid-range model in Kassow Robots' seven-axis KR series. All Kassow robots incorporate a seventh axis as a standard feature rather than an optional joint, based on the company's philosophy that 6-DOF cobots systematically under-serve real-world assembly tasks that require complex approach angles. The seventh axis provides redundancy — for any given TCP position and orientation, multiple joint configurations exist, allowing the controller to select the configuration that avoids singularities, joint limits, and collisions with fixtures.
Technical Specifications
Payload is 8 kg at a 1000 mm reach. The arm has seven revolute joints, with the seventh providing wrist rotation redundancy. Repeatability is ±0.05 mm, consistent with collaborative robot standards. Maximum TCP speed exceeds 2 m/s. The arm weighs 14 kg and uses a standard 50 mm flange for end-effector attachment.
Safety and Collaboration
The KR810 is certified to ISO 10218 and ISO/TS 15066 collaborative operation standards. Force and torque sensing across all joints enables safety-rated stop in response to contact, allowing deployment without permanent guarding subject to risk assessment.
Software Ecosystem
Kassow provides an intuitive tablet-based teach interface. The robot supports URScript-compatible programming (leveraging familiarity from the Universal Robots ecosystem) and standard fieldbus interfaces including EtherNet/IP, PROFINET, and Modbus TCP.
Target Applications
Screwdriving in recessed or obstructed positions, complex assembly paths on automotive body parts, machine tending with awkward loading positions, and quality inspection with vision systems mounted on the arm flange are the primary use cases where the seventh axis delivers measurable productivity advantage over six-axis alternatives.
FAQ
Why does the Kassow KR810 have seven axes instead of the standard six?
The seventh axis provides kinematic redundancy. For any given tool position and orientation, a seven-axis robot has multiple valid joint configurations, allowing it to select the configuration that avoids singularities, joint limits, and physical obstacles. This is particularly valuable for screwdriving in recessed positions and complex assembly paths where six-axis cobots require base repositioning.
What payload and reach does the KR810 offer?
The KR810 carries 8 kg at a 1000 mm reach. This positions it for mid-size assembly, material handling, and machine tending tasks that are too heavy for lightweight cobots but do not require the payload of full industrial six-axis robots.
Is the KR810 safe to use alongside human workers?
Yes. The KR810 is certified to ISO 10218 and ISO/TS 15066 collaborative standards, with joint-level force and torque sensing that triggers a safety-rated stop on unexpected contact. Deployment without permanent safety guarding is permissible subject to a site-specific risk assessment.
Is the KR810 compatible with Universal Robots programming experience?
Kassow supports URScript-compatible syntax, meaning engineers with Universal Robots programming experience can apply much of their existing knowledge to the KR810. The tablet-based teach interface also provides an alternative for operators without scripting experience.
What fieldbus protocols does the KR810 support?
The KR810 supports EtherNet/IP, PROFINET, and Modbus TCP, covering the most common PLC communication standards in automotive, electronics, and general manufacturing environments.
