What is a cobot and how does it work?

Cobots, or collaborative robots, are a major advancement in the field of robotics. Unlike traditional industrial robots, these machines are designed to work closely with human operators without physical barriers.

Thanks to their built-in sensors and advanced safety systems, cobots ensure safe and productive interaction with their surroundings. This new approach to automation paves the way for more flexible, accessible, and efficient solutions tailored to the challenges of Industry 4.0.

A collaborative robot, or cobot, is a type of industrial robot designed to work safely alongside humans without requiring physical separation, such as cages or barriers. Unlike traditional industrial robots, cobots integrate advanced safety and adaptability features, making them highly versatile and intuitive.

The origin and evolution of cobots

The concept of collaborative robotics emerged in the 1990s with the idea of complementing human skills rather than replacing them. This vision led to the development of robots capable of meeting diverse industrial needs while adhering to strict safety standards.
Companies like FANUC were pioneers in this field. Today, cobots are used in a wide range of industries, from automotive assembly lines to pharmaceutical laboratories and the food sector.

Cobots stand out due to their advanced technological architecture, combining safety, flexibility, and performance.

Detection and safety systems

Cobots are equipped with sophisticated sensors such as 3D cameras, LIDAR and force sensors. These devices detect operators' movements and adjust their behavior in real time. For example, if a cobot detects a human presence too close, it automatically slows down or stops to avoid any risk of collision.

Intuitive cobot programming

Thanks to simplified user interfaces (often based on drag-and-drop), cobots can be programmed by non-specialist operators. This accessibility reduces integration costs and speeds up commissioning.

The mechanical flexibility of cobots

The articulated arms of cobots mimic human movements, enabling them to perform complex tasks with great precision.

Cobot communication and connectivity

Cobots are compatible with the main industrial protocols, such as OPC-UA, facilitating their integration into existing production lines.

Integrating cobots offers several strategic advantages:

• Reduced costs: Cobots are often less expensive than traditional robots, with limited maintenance needs.
• Enhanced safety: Built-in sensors reduce the risk of workplace accidents.
• Operational flexibility: Ideal for rapid production changes, cobots provide unmatched versatility.
• Increased productivity: By handling repetitive tasks, cobots free up time for operators to focus on higher-value activities.

What is the cost of a cobot?

The price of a cobot generally varies between 20 000$ and 50 000$ USD, depending on the model and specific functionalities. This may seem a high price, but it's still lower than that of traditional robots, thanks in particular to reduced infrastructure requirements.

Return on investment (ROI)

Cobots offer an attractive ROI through:

• Lower installation costs: No need for physical barriers or heavy infrastructure.
• Increased productivity: By automating repetitive tasks, operators can focus on more valuable activities.
• Enhanced flexibility: Easily reconfigured for new tasks, cobots adapt to changing needs.
• Reduced labor costs: Cobots enable cost savings while maintaining consistent and efficient production.
