State detecting method, robot and mobile device
First Claim
1. A method for detecting a state of a mobile device, comprising:
- disposing a plurality of depth sensors on a side surface of the mobile device;
obtaining detection signals of the depth sensors; and
determining whether the mobile device is in a lifted state, a tilted state, or an edge-bordering state based on a numerical value of each of the detection signals, wherein the lifted state is defined as the mobile device being suspended off a support surface, the tilted state is defined as one of two ends of the mobile device being suspended off the support surface with the other end of the mobile device contacting the support surface, and the edge-bordering state is defined as the mobile device being adjacent to the edge of the support surface, wherein when a change in the detection signal for some of the depth sensors surpasses a second threshold value, while the rest of the detection signals keep unchanged, the mobile device is determined to be in the tilted state, and when the change in the detection signal for some of the depth sensors surpasses a third threshold value greater than the second threshold value, while the rest of the detection signals keep unchanged, the mobile device is determined to be in the edge-bordering state.

Abstract
A state detecting method applied to a mobile device includes: arranging a depth sensor at the bottom of the mobile device, obtaining a detection signal of the depth sensor, and determining if the mobile device is in a lifted state, a tilted state, or an edge-bordering state, based on the numerical value of the detection signal of the depth sensor. The lifted state is associated with the mobile device without contacting with a support surface. The tilted status is associated with one end of the mobile device contacting the support surface and the other end of the mobile device without contacting the support surface. The edge-bordering state is associated with the mobile device located at the edge of the support surface. Accordingly, when the mobile device is in any of the aforementioned states, an appropriate response can be implemented.
