Family of six-axis cobots can handle payloads up to 18kg
Published:  09 August, 2023

Schneider Electric has launched a family of collaborative robots (cobots) in five sizes, with payloads from 3–18kg, working radii from 626–1,327mm, operating speeds from 1.5–3.5m/s, and positioning repeatabilities from ±0.02mm to ±0.03mm. The Lexium cobots are claimed to have some of the smallest footprints in the industry and to need 30-40% less space than traditional robots.

The six-axis cobots, which have already been demonstrated at various trade exhibitions including the UK’s PPMA Show in 2022, are designed to work alongside humans. They take safety into account with built-in collision detection, rounded edges and low weights reducing the risk of injury. They avoid the need for additional safety equipment.

Simple programming, quick set-ups, and ease of use and training are said to help recover investment costs faster. Installing the IP54-protected cobots requires minimal changes to existing layouts. They can be mounted on floors, walls or ceilings,

The cobots can be taught motion profiles by manually guiding the arm. This hand-guided teaching simplifies the programming process and eliminates the need for detailed parameterisation of motion settings. The cobots are ready for use quickly and can also be adjusted to new conditions at short notice in the event of retooling. Specialised knowledge of programming or commissioning is not needed.

Graphic programming can also be used to change applications easily and to adapt to production changes.

The cobots integrate with Schneider’s EcoStruxure open, interoperable, plug-and-play platform, cutting design, development and commissioning times, and making delivery and start-up quick and easy. They can link with the EcoStruxure Machine Expert Twin tool which provides simulation and digital twin functions.

“The release of the Lexium cobot marks a crucial step in next-generation robotic systems,” says Mike Teller, Schneider Electric’s global OEM strategy and sustainability leader. “Traditional industrial robotic systems must be designed into processes from day one. Although they can be very effective at accurately and consistently performing operations which are repetitive and arduous for workers, their speed and power make them unsuitable to work alongside people.

“The Lexium cobot, on the other hand, is intentionally designed to work with people, and offers a fast return on investment, easy integration without the capital costs of major process rework, and helps make plant more agile, productive, and safe environments.”
