Schneider Electric has developed a new collaborative robot for safe collaboration between man and machine. The so-called Lexium Cobot is available in five model variants and can be retrofitted as a 
standalone solution in almost any industrial plant. Thanks to constant monitoring of torque and speed, the tech group's first collaborative robot can also perform extremely careful and gentle movements. In contrast to classic robotics applications, it is possible that further protective devices can be dispensed with. The extremely mobile robot arm is programmed purely graphically and can be adjusted to new movement profiles using hand-guided teaching.
Instead of faster, higher, further: Careful mobility makes man and machine more efficient
Unlike conventional industrial robots, which usually come up with high acceleration and immense forces, cobots can work in close proximity to their human colleagues. The lightweight robots are equipped with safety protocols as standard and have sensitive force monitoring to detect a collision. This qualifies them for a variety of applications that would not be possible with conventional industrial robots.
Lexium Cobot robot series increases safety and efficiency
The first cobot from Schneider Electric is available in a total of five versions. These differ in terms of size, payload (3 to 18 kg) and working radius. All models in the range have torque monitoring to detect a collision. In the event of unexpected contact, a safety protocol ensures that the aluminum gripper arm immediately interrupts its movement. Rounded edges and the overall low weight further reduce the risk of injury. Depending on the application, this eliminates the need for additional safety equipment, which saves around 30 to 40 percent of space compared to traditional industrial robots.
What also distinguishes the Lexium cobot models from Schneider Electric is their high mobility. Due to the total of six axes, practically any movement profile can be realized. And not only in systems in which the Schneider cobot is firmly integrated. Thanks to its own PLC control, the robot arm can also be used as a standalone solution and can be connected upstream or downstream of machine processes – for example, when it comes to handing over workpieces to a human or stacking packaged goods.
Handheld teaching and graphical programming
Another special feature of Schneider Electric's new collaborative robot is graphical programming. Apart from a certain amount of basic technical knowledge, this does not require any specific training. The cobot also learns how to perform certain tasks by teaching it the required movement profile by manually guiding the robot arm. This so-called hand-guided teaching results in a further simplification of the programming process and makes the small-scale parameterization of motion settings superfluous. In this way, the Lexium Cobot is ready for use very quickly and can also be adapted to new conditions at short notice in the event of conversions. Special expertise for programming or commissioning is not required.
At Schneider Electric, Lexium Cobot is part of the Ecostruxure Machine holistic automation platform. The portfolio includes additional robots, transport systems (Lexium MC12 – Multi Carrier), motion controllers and drives as well as a uniform software solution for all stages of machine development.
