Latest Doosan cobots claim competitive advantages, widen the Mills CNC Automation offer

​The A-series and H-series Doosan cobots from Mills CNC Automation, a division of Mills CNC, comprise six new models in total, complementing and expanding the M-series (comprising four models) previously launched in 2018.

The A-series, accredited by the international testing and certification organisation - TUV SUD -has a number of USPs, the most notable of these being the cobots’ high-speed, safety, versatility and affordability.

The series comprises four different models: the A0509, A0509s, A0912 and A0912s, and boast a payload capacity from 5 to 9 kg, and a reach from 900 to 1,200 mm.

A-series cobots feature an advanced safety algorithm that makes them ideal for operating in a wide range of manufacturing and production environments, and takes collision detection sensitivityand safety beyond existing levels, it is claimed.

The cobots are fast with impressive speed and acceleration characteristics. A-series’ joint (axis) speeds are twice that of competitor cobots currently available on the market, says Mills CNC Automation.

Says Peter McCullough, Mills CNC Automation’s product manager (Doosan Robotics): “Cobot operating and processing speeds are important. They help reduce cycle times and, as a consequence, improve customers’ productivity levels which, in turn, impacts (positively) on their ROI.”

Two of the A-series cobots (A0509s and A0912s) are equipped with force sensor technology that increases their application potential to include delicate tasks requiring ‘human- like’ dexterity such as polishing and intricate assembly operations.

The H-series cobots are half the weight (75 kg) of comparable cobots in their class, resulting in low inertia and enhanced safety. H-series cobots are also the most powerful on the market, the company claims.

There are two models in the series - the H2017 and the H2515. The H2017 has a payload capacity of 20 kg and a reach radius of 1,700 mm, the H2515 has a payload capacity of 25 kg and a reach radius of 1,500 mm.

Both models are equipped with six torque sensors integrated on their (6-axis) arms which if/when detecting any changes in force or pressure causes the cobots to stop in their tracks.

Adds McCullough: “Safety is critically important. Torque sensors help shut down the cobot immediately once torque thresholds have been exceeded, preventing injury to humans or to the cobot itself.”
