Kassow Robots KR1205 — Specs & Review

Specifications

Key features

• 7-axis kinematics with 12 kg payload and 1500 mm reach — largest in the KR series
• Extended reach enables full coverage of large workpieces from a single base position
• Wrist redundancy allows complex approach angles without base repositioning
• ISO 10218 / ISO/TS 15066 certified for collaborative operation
• URScript-compatible programming familiar to UR ecosystem users
• EtherNet/IP, PROFINET, and Modbus TCP fieldbus support
• ±0.05 mm repeatability for assembly and dispensing tasks
• Standard 50 mm ISO flange for broad end-effector compatibility

Overview

The KR1205 is Kassow Robots' high-payload, long-reach seven-axis cobot, designed for applications where both reach and carrying capacity push beyond what mid-range cobots can address. The combination of 1500 mm reach and 12 kg payload is unusual in the collaborative robot market, where most offerings top out at shorter reaches or lower payloads to stay within collaborative safety limits. Kassow achieves this combination while maintaining ISO/TS 15066 certification through refined joint sensing and speed management.

Technical Specifications

Seven revolute axes with the seventh providing wrist redundancy. Reach is 1500 mm with a 12 kg payload. Repeatability is ±0.05 mm. Maximum TCP speed exceeds 2 m/s. The arm weighs approximately 18 kg and uses a standard 50 mm ISO flange. Joint torque sensing across all seven axes enables safety-rated stops.

Extended Reach Applications

The 1500 mm reach allows the KR1205 to service large workpieces from a fixed base position, reducing the number of fixtures and base repositioning events required compared to shorter-reach cobots. In automotive manufacturing, this enables single-robot coverage of door panels, bumper assemblies, or instrument panel sections.

Payload Capacity

12 kg gross payload accommodates heavier end-effectors without sacrificing workpiece capacity. Multi-function heads combining vision, dispensing, and fastening can be mounted without depleting the full payload budget.

Software and Integration

URScript-compatible programming, tablet teach interface, EtherNet/IP, PROFINET, and Modbus TCP are all consistent with the KR810 platform, providing a common integration path across the KR series.

FAQ

How does the KR1205 differ from the KR810?

The KR1205 offers greater payload (12 kg vs 8 kg) and longer reach (1500 mm vs 1000 mm), making it suitable for larger workpieces and heavier end-effectors. Otherwise the architecture — seven axes, URScript compatibility, collaborative certification — is shared across the KR series.

What applications benefit most from the KR1205's extended reach?

Large-workpiece applications such as automotive panel assembly, fuselage section processing, and large enclosure handling benefit most from 1500 mm reach. The robot can cover a larger surface from a fixed base position, reducing fixture changes and cycle time compared to shorter-reach alternatives.

Can the KR1205 operate collaboratively despite its 12 kg payload?

Yes. The KR1205 is certified to ISO/TS 15066 for collaborative operation. Joint torque sensing triggers a safety-rated stop on unexpected contact. Users should conduct a site-specific risk assessment, as collaborative operation at full payload and speed may require additional risk mitigation measures per local regulations.

Is the KR1205 compatible with the same programming tools as the KR810?

Yes. The entire KR series shares URScript-compatible programming, the tablet teach interface, and identical fieldbus support (EtherNet/IP, PROFINET, Modbus TCP), enabling a common integration architecture across Kassow models.

What payload is available for the workpiece after accounting for end-effector weight?

The 12 kg payload is the gross capacity including the end-effector. A typical pneumatic gripper with tooling weighs 2–4 kg, leaving 8–10 kg for workpiece handling. Heavier multi-function heads will reduce the available workpiece payload proportionally.
