What is a Collaborative Robot ?

Collaborative Robot

Mr. Jeff Winter

A cobot (short for collaborative robot) is a robot intended for direct human-robot interaction within a shared space. Traditionally industrial robots have been completely isolated from human interaction.

The idea of cobots was invented in 1996 by J. Edward Colgate and Michael Peshkin, professors at Northwestern University. The idea of collaboration between human and machine opens the doors for many new ways of increasing productivity and quality.

Cobots offer the most value in situations where a human needs to be in close proximity to the robots, including:
• Pick and place
• Material handling (especially between different process stages)
• Process tasks requiring tools
• Quality Inspection
• ‘learn to follow’ applications (where the Cobot is taught to move along a predefined motion path)

The International Federation of Robotics defines four levels of collaboration between industrial robots and human workers:
• 𝐋𝐞𝐯𝐞𝐥 𝟎 (𝐅𝐞𝐧𝐜𝐞𝐝 𝐫𝐨𝐛𝐨𝐭 𝐜𝐞𝐥𝐥): Humans and the robots are fully separated in space; there is no collaboration
• 𝐋𝐞𝐯𝐞𝐥 𝟏 (𝐂𝐨𝐞𝐱𝐢𝐬𝐭𝐞𝐧𝐜𝐞): Human and robot work alongside each other without a fence, but with no shared workspace.
• 𝐋𝐞𝐯𝐞𝐥 𝟐 (𝐒𝐞𝐪𝐮𝐞𝐧𝐭𝐢𝐚𝐥 𝐂𝐨𝐥𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐢𝐨𝐧): Human and robot are active in shared workspace but their motions are sequential; they do not work on a part at the same time.
• 𝐋𝐞𝐯𝐞𝐥 𝟑 (𝐂𝐨𝐨𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧): Robot and human work on the same part at the same time, with both in motion.
• 𝐋𝐞𝐯𝐞𝐥 𝟒 (𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐢𝐯𝐞 𝐂𝐨𝐥𝐥𝐚𝐛𝐨𝐫𝐚𝐭𝐢𝐨𝐧): The robot responds in real-time to movement of the human worker.

The collaborative robotics (cobots) market is predicted to exceed $24 billion by 2030. (Source: ABI Research)

In 2015, the collaborative robotics market was valued at just $95 million. By the end of 2019, it was worth a little over $1 billion. Reports predict an increase with a CAGR of 28.6% till 2030. (Source: ABI Research)
