About SUM
SUM develops autonomous-mobility technology in South Korea under the SMOBI name. Its work includes automated-driving software, vehicle-control hardware and remote-driving systems that can be integrated into passenger, shuttle and specialist mobility platforms.
The stack connects perception and driving decisions with drive-by-wire controls and a remote-supervision layer for intervention or low-speed operation. SUM works with vehicle and service partners on configured programmes rather than manufacturing every base vehicle. Deployment maturity depends on the route, operating domain and local authorisation.
