Core principles of collaborative robots

April 11, 2019 | Best Practices | Automation

Robotic design: Built-in collaborative force/torque sensing, safety features, and improved precision enable faster integration in a wider range of future-proofed applications.

Fast set-up, easy programming, flexible deployment, and safe operation are the four core principles that define collaborative robots. A lot of people mistake collaborative robot design as only being about safety; that’s just the cost of entry.

Upgrading the collaborative robot’s internal features has strengthened each of those four core principles. Built-in force torque sensing, safety features, and improved precision enable faster integration in a wider range of future-proofed applications. Increased repeatability makes collaborative robots suitable for precise finishing, assembly, and electronics tasks.

Built-in force torque sensors

A collaborative robot with built-in force torque sensors enables force torque applications out-of-the-box and makes teaching the robots easier.

Universal Robots’ new e-Series line of collaborative robots has built-in force/torque sensingUniversal Robots’ new e-Series line of collaborative robots has built-in force/torque sensing. Universal Robots e-Series line of collaborative robots won a 2019 Engineers’ Choice Award in the Motion Control category.

In a polishing application using the same polishing tool a human would hold, a collaborative robot can use the manual tool. In a separate demonstration, a gripper moves down until it feels a small resistance. Then it opens and grips a part. There’s no need for an external sensor to sense contact with built-in force torque sensors.

Human-machine collaboration

Manufacturing needs to consider the human value and safety, craftsmanship, and the understanding of the consumers, materials, and processes. Those are core parts of a factory’s value creation. It’s not just robots that create this value; humans working with the robots also create more value for a company.

Trends such as mass personalization involve using technology to return human value improve manufacturing. Collaborative robots are what companies need to produce the personalized products consumers demand.

The new e-Series line of collaborative robots feature an updated user interface enabling faster integration with end-effectors and peripherals through the UR+ platformThe new e-Series line of collaborative robots feature an updated user interface enabling faster integration with end-effectors and peripherals through the UR+ platform.

Far from fenced-off industrial robots that replace human workers with automated processes, collaborative robots enhance human craftsmanship with the speed, accuracy, and precision required to make modern products. Collaborative robots bring the human touch to the masses.
