'Robot suitcases' take weight off for travelers

LAS VEGAS - Self-driving cars may take a while to arrive, but the self-driving suitcase is here now.

Some of the technologies used in autonomous cars have been adapted in products unveiled at the 2018 Consumer Electronics Show in Las Vegas, to help travelers with the weighty problem of dealing with baggage.

The "robot suitcase" from California-based startup Travelmate can be controlled with a smartphone app and can roll alongside its owner at speeds up to 11 kilometers per hour, navigating around obstacles.
