The company previously invented a moveable armchair with similar technology named ProPILOT, which can detect the distance to other chairs and move back to its original spot by following a given trajectory. /Photo via VCG

ProPILOT technology can also autonomously park cars by controlling steering, speed and gear shifting. /Photo via VCG
