To resolve the challenge, TechBrew Robotics, a Kawasaki Robotics Preferred Integrator, designed a custom solution using Kawasaki’s R series robots and F60 controller.

The robots’ task may seem simple: after the sandwiches are halved in the cutting machine, the robots need to stack one half on top of the other, making it easier for human workers to package them manually. However, this application was tricky to automate. Sandwich halves vary in their position as they come out of the cutting machine, so the robot would need some sort of vision intelligence to recognise the location of each half on the conveyor.
