The robot was able to roam around the compound on its own with a margin of error of 10 cm and carry out safety procedures, such as monitoring temperatures of the facility equipment, according to the telecom operator.

LG Uplus said the robot is also able to accurately position itself for autonomous driving by using the mobile carrier's real-time kinematic technology that sends positioning data  seamlessly through the low latency 5G network.

"The autonomous robot will be core equipment for the refinery industry, which prioritizes safety," Seo Jae-yong, head of LG Uplus' convergence business, said in a statement.

"We plan to wrap up further testing by the end of this year and commercialize the product next year."
