Abstract
Embodiments of the present invention relate to a self-propelled device. The self-propelled device includes: a body defining a first space and a second space in communication with the first space, wherein the volume of the second space is less than the volume of the first space and the second space is closer to an edge of the body than the first space; a moving module adjacent to the body; an air extraction module disposed on the body and in communication with the first space; and an air pressure sensor disposed on a side of the second space. The self-propelled device is configured to move on a panel surface.
Claims19
A self-propelled device, comprising:
- a body defining a first space, a second space and a third space, wherein the third space is in communication with the first space, and the second space is in communication with the first space via the third space, wherein a volume of the second space is less than a volume of the first space and the second space is closer to an edge of the body than the first space;
- a moving module adjacent to the body;
- an air extraction module disposed on the body and being in communication with the first space;
- and
- an air pressure sensor disposed on a side of the second space,
- wherein the self-propelled device is configured to move on a panel surface,
- wherein the second space is in communication with the panel surface through an opening of the second space,
- wherein the body comprises a connecting passage, the third space is in communication with the first space via the connecting passage, and the second space is in communication with the first space via the connecting passage and the third space,
- wherein when an edge of the self-propelled device extends beyond a border of the panel surface, then the second space is in communication with an external environment via the third space, and the first space is in communication with the external environment via the connecting passage and the third space.
