Abstract: A positioning navigation method and an electronic apparatus thereof are provided. The positioning navigation method is adapted to the electronic apparatus for positioning an indoor environment and includes the following. A movement process is executed from a start position. In the movement process, distance detection is continuously performed by first sensors, orientation detection is continuously performed by a second sensor, and a position coordinate is recorded every first time period. When sensing that a distance between the electronic apparatus and an obstacle falls in a predetermined distance range, a direction changing process is executed. In the direction changing process, the electronic apparatus rotates by a rotation angle, and an intermediate position coordinate is recorded every second time period. After the direction changing process, a position coordinate corresponding to the direction changing process is determined, and the movement process is re-executed.

Abstract: A cultivating box comprises a micro control unit (MCU), a memory module, a light adjusting module and a container having a cultivating space for cultivating plants is presented. The memory module records a plurality of parameters respectively corresponding to different growth conditions needed by the plants in different growth stages. The MCU applies corresponding parameters of the plurality of parameters recorded in the memory module to control the light adjusting module in each growth stage of the plants for adjusting the light status of the container, so the environment of the container can satisfy the requirement of the plant in every growth stage.
