BCIT is incorporating collaborative robots or cobots into its welding and metal fabrication programs.

A cobot is a type of lightweight robot arm that can safely share workspaces with humans, while performing automated tasks without the use of complex programming codes.

“Students don’t need to know anything about computer programming to be able to set the system up. Learning how to use this technology will allow them to go out into the work environment and know where and how a collaborative robot could be used,” said Mathew Smith, director of the Centre for Welding Technologies and Metallurgy.

Cobots are commonly used to support manufacturing and assembly tasks. The lower cost, smaller size, and ease of use without specialized programming expertise make the cobot more favourable than traditional robots. The main difference between a traditional robot and a cobot is that the latter can detect human presence and adjust its behaviour accordingly.

“If you’re working around a cobot, it will detect you and stop if you get on its way – making it safer to work around, whereas traditional robots don’t work that way because they have already been programmed to perform a specific task regardless of the circumstance,” explained Smith.

Students will be able to automate common tasks including the welding of pipe and structural joints, including groove and fillet welds. A camera has also been mounted on the robot arm to allow students to monitor the welding in real time.

The cobot will be used to supplement the training already provided in these programs and will not replace the learning of critical hand skills required to become a certified welder in British Columbia.

Currently, only a minimal amount of the welding work carried out in B.C. incorporates the use of automation.
