Collaborative Robotics (Cobots): A Revolution for SMEs

Collaborative Robots (Cobots): In Brief

Collaborative robotics, or "cobot technology," represents a major advancement in industrial automation, particularly well-suited to the needs of small and medium-sized enterprises (SMEs). These robots are designed to work alongside humans, combining safety, flexibility, and accessibility, thereby radically transforming the automation possibilities for mid-sized companies. With an average investment ranging from CAD 50,000 to CAD 150,000 and a deployment time of 4 to 8 weeks, cobots offer an accessible automation solution. In this article, we will examine in detail the technical, economic, and practical aspects of cobots, their impact on industrial production, and their role in the digital transformation of SMEs.

Definition and Principles of Operation of Cobots

Collaborative robotics distinguishes itself from traditional industrial robotics by its ability to share the workspace with human operators. Cobots integrate sophisticated sensors and advanced control systems that enable them to detect human presence and adjust their behavior accordingly. Compared to traditional industrial robots, which require safety barriers and occupy an average area of 15 m², a cobot can operate in a space of 2 to 3 m².

Key Technical Specifications of Cobots

Current cobots offer:

• Payload: 3 to 35 kg depending on models
• Reach: 500 to 1300 mm
• Repeatability: ±0.03 mm
• Maximum speed: 1.5 m/s in collaborative mode
• Force sensors: sensitivity from 0.1 to 1N
• Vision systems: resolution up to 0.5MP
• Reaction time: <2ms for collision detection

Practical Applications of Cobots in the Manufacturing Industry
