New Application Areas

While currently focused primarily on manufacturing, collaborative robots may find applications in other sectors such as healthcare, agriculture, and service industries.

Implementing Collaborative Robots: Best Practices

For manufacturers considering the adoption of collaborative robots, following best practices can help ensure a successful implementation.

Conduct a Thorough Assessment

Begin by assessing your current processes and identifying areas where collaborative robots could provide the most significant benefits. Consider factors such as task complexity, repetitiveness, and ergonomic challenges.

Start Small and Scale Up

Rather than attempting a large-scale implementation, start with a pilot project in a specific area of your production process. This allows you to gain experience and demonstrate the benefits before expanding to other areas.

Invest in Training

Provide comprehensive training for employees who will be working with or programming the cobots. This should cover not only technical aspects but also safety procedures and collaborative work practices.

Prioritize Safety

While cobots are designed with safety in mind, it’s essential to conduct thorough risk assessments and implement appropriate safety measures for your specific application.

Foster a Collaborative Culture

Encourage a positive attitude towards human-robot collaboration by clearly communicating the benefits and addressing any concerns employees may have.

Plan for Maintenance and Support

Develop a maintenance strategy and ensure you have access to technical support, either in-house or through your cobot supplier.
