Cobots fill engineering labor gap and enables 24-hour operation

GKN Driveline was looking for a solution where they can automate the high level experience and sense of operators and at the same time allowing humans and robots to safely coexist. They decided to introduce UR cobots that meet, these criteria. Mr. Hidefumi Yoshida, Senior Manager, Manufacturing Engineering Section says: “The reason why we selected UR was that they were already adopted by a major Japanese car manufacturer. The payload also met our needs.” First, a UR5 cobot was introduced to the gear assembling process, replicating the sense of human touch provided by the operators. “Using the external torque sensor and gripper from Robotiq, selected from the UR+ portfolio, we succeeded in reproducing it of trial and error,” says Mr. Sakamaki. GKN also considered safety. For example, zone sensors are set in 4 different directions, which sets the robot in slower motion when people are around.

When introducing the UR cobots, Mr. Sakamaki, Mr. Kikumoto and a total of seven people attended the three-day core training provided by an official distributor of UR cobots, Kantum Ushikata Corporation. Mr. Yoshida concludes; “We purchased another UR robot for demonstration purposes to encourage other departments to try and consider applying UR robots to other production processes. As a UK-based company, all the companies in the GKN group have a culture of trying new things and share successful experiences. This case story became another good example for our Japanese operation to share with GKN departments in other countries. We will strive to make proactive efforts so that humans and robots can coexist.”
