SEOUL -- The remote control operation of an autonomous construction machine, based on a fifth-generation mobile network, was successfully demonstrated during a trade fair in Shanghai, according to Doosan Infracore, a top construction machinery manufacturer in South Korea.
The event supervised by Doosan Group chairman Park Jeong-won took place at Doosan's exhibition booth on Thursday on the first day of the three-day Bauma China exhibition, the group said in a statement. "The demonstration of remote control was carried out successfully without error."
From a remote control center in Shanghai, an operator activated an excavator at a site in the western port city of Incheon. A low-latency image transmitter sent highly-compressed 3D image data shot by five cameras mounted on the excavator.
"Quality should be basic, and now we have to win the Chinese market with digital innovation," Park was quoted as saying.
Doosan Infracore, a key Doosan group unit, has teamed up with LGU+, the third-largest mobile carrier, to develop self-driving construction machines using a 5G communication network, drones, and ultra-low latency video transmission technology. In April, the company acquired an unspecified stake in PoteNit, a start-up specializing in autonomous mobile industrial robots.
Autonomous machines would transmit the 3D image of construction sites photographed by a drone to the server in real time and automatically calculates the workload. Unmanned excavators could be deployed in dangerous environments.
