A learning toy which enables learning of high-level programming in a stepwise manner. A movement path is constituted by a plurality of command panels in which command information which can be read with an optical reading module is recorded being arranged. A mobile robot sequentially reads command information included in the command panels through which the mobile robot passes while moving along the movement path and stores a plurality of pieces of command information in a command information memory. The mobile robot takes out a plurality of pieces of command information from arbitrary positions in the command information memory to execute operation. If a plurality of pieces of command information necessary for operation of the mobile robot are stored in the command information memory, a control unit of the mobile robot automatically extracts and takes out the command information and causes the mobile robot to operate.
