Abstract

A robotic shoe includes a robot sole, a plurality of optical sensors, a plurality of optical sensors, and projections. The robot sole has an underside capable of contacting the ground when in use. Mounting spaces are longitudinally spaced in the sole. The optical sensors are disposed in respective ones of the mounting spaces. The projections protrude from the underside of the sole, and are capable of contacting the ground at positions corresponding to the mounting spaces.

Claims

1. A robotic shoe, comprising:

a robot sole having an underside capable of contacting the ground when in use;

a plurality of mounting spaces longitudinally spaced in the sole;

a plurality of optical sensors disposed in respective ones of the mounting spaces; and

projections protruding from the underside of the sole, which are capable of contacting the ground at positions corresponding to the mounting spaces when in use.

2. The robot shoe of claim 1, wherein the mounting spaces are formed in a width direction of the sole.

3. The robotic shoe of claim 1, wherein the optical sensors are disposed on tops of the mounting spaces and configured to radiate light downward from above.

4. The robotic shoe of claim 1, wherein the optical sensors are configured to sense distances from the optical sensors to bottoms of the mounting spaces and operate when a sensed distance value is equal to or less than a predetermined value.

5. The robotic shoe of claim 1, further comprising a controller configured to determine an intention of walking on the basis of the order of sensed signals of the optical sensors.

6. The robotic shoe of claim 1, wherein the optical sensors are non-contact type photosensors.

7. The robotic shoe of claim 1, wherein when the projections come in contact with the ground, bottom portions of the mounting spaces are pushed into the mounting space and a distance between the optical sensors and the bottom portions of the mounting spaces is decreased.

8. The robotic shoe of claim 1, wherein portions of the sole where the mounting spaces are formed in the sole are made of an elastic material.
