M0609

Overview

The Doosan Robotics M0609 is a 6-axis collaborative arm from Doosan Robotics, the robotics division of South Korean conglomerate Doosan Group. It offers 6 kg payload and 900 mm reach at a price point around £14,000 new, which is competitive against Universal Robots' comparable models. Doosan equips all of its cobots with 6-axis force-torque sensing at the tool flange, collision detection across all joints, and a safety-rated monitoring function that exceeds the minimum ISO/TS 15066 requirements.

Key Specifications

• Payload: 6 kg
• Reach: 900 mm
• Degrees of freedom: 6
• Repeatability: ±0.05 mm
• TCP speed: 1 m/s
• Weight: 27 kg
• IP rating: IP54
• Safety: ISO/TS 15066, Cat.3 PLd certified

The M0609 includes a built-in 6-axis force-torque sensor as standard, which on many competing arms is an optional extra. This simplifies force-controlled assembly applications such as peg-in-hole insertion and surface following.

Use Cases

The M0609 is used in electronics assembly, light machine tending, quality inspection, and collaborative pick-and-place. Its built-in force-torque sensing makes it well-suited to compliant assembly tasks. Doosan's DART (Doosan Automated Robot Teaching) programming interface runs on a touchscreen pendant and supports direct teach-by-demonstration.

Buying Used

Doosan cobots are less established in the UK secondhand market than UR or FANUC equivalents, though availability is growing as first-generation deployments reach end-of-lease. Expect to pay £7,000 to £13,000 for a used M0609. UK service support is provided through Doosan Robotics' European distributor network. Verify that the controller software version is current and that the force-torque sensor has been calibrated within the last 12 months.

Alternatives to Consider

• Universal Robots UR5e: Larger install base, broader third-party ecosystem, and better UK resale liquidity.
• ABB GoFa CRB 15000: Higher TCP speed with IP67 body protection.
• Kinova Link 6: Lighter arm suitable for mobile platforms, though at a higher price.
