5G technology lets Doosan remotely control excavator 8500km away

DOOSAN has claimed to be the first manufacturer at bauma 2019 to use 5G technology for worldwide ‘TeleOperation’ of construction machines.

The firm is operating a DX380LC-5 40-tonne crawler excavator located over 8500 km away in Incheon in South Korea, from an operator’s booth on Doosan’s bauma stand in Munich.

TeleOperation has been co-developed with LG U+, a South Korean telecommunications and data services firm. Doosan said the TeleOperation demonstration is the first to remotely control a machine across such a large distance between locations which have a time difference of eight hours, using 5G telecommunications technology.

For TeleOperation to function properly, Doosan explained it is vital to deliver live video streaming at the operator’s station in a reliable way with minimal time lag. The manufacturer said the new 5G network provides ten times faster bandwidth and ten times lower latency (signal delay) than the 4G network.

Features include a low-latency video transmission module with fast video transfer. LG U+ has also introduced new modules providing low latency image processing to further minimise delay.

While it can be used for general earthmoving applications, the new TeleOperation system is said to be ‘ideal’ for operating machines in dangerous applications such as industrial waste disposal, involving hazardous, toxic or radioactive substances.
