Abstract
A self-propelled electronic device comprising: a housing; drive wheels that enable the housing to travel; a travel control unit that controls travel of the housing; and a periphery detection sensor that detects a region around the housing where the device is unable to travel, wherein the drive wheels include a left drive wheel and a right drive wheel which are independently driven, and the travel control unit: causes the left drive wheel and the right drive wheel to move backward in such a manner that an amount of rotation of the left drive wheel is smaller than an amount of rotation of the right drive wheel, when the periphery detection sensor detects that there is a region where the device is unable to travel at front left of the housing; and causes the left drive wheel and the right drive wheel to move backward in such a manner that an amount of rotation of the right drive wheel is smaller than an amount of rotation of the left drive wheel when the periphery detection sensor detects that there is a region where the device is unable to travel at front right of the housing.
