Module fiducial markers for robot navigation, address markers and the associated robots
First Claim
1. A module for robot navigation, wherein the module comprises a whole workspace area for robot traveling divided into a plurality of module areas, and each module area is internally provided with:
- a first magnetic strip arranged in the Y-axis direction, the first magnetic strip having a polarity of an N pole or an S pole;
a second magnetic strip arranged in the X-axis direction, the second magnetic strip having a polarity different from the polarity of the first magnetic strip;
a third magnetic strip arranged in the X-axis direction, wherein the polarity of the third magnetic strip is the same as the polarity of the second magnetic strip; and
address markers, wherein each module area is provided with a unique address marker,wherein the first magnetic strip has a different length than the second magnetic strip,wherein the magnetic strips having the same polarity intersect.

Abstract
The present invention discloses a module for robot navigation, an address marker and an associated robot. The module divides a whole workspace area for robot traveling into a plurality of module areas, and each module area is internally provided with a first magnetic piece having a polarity of an N pole or an S pole and a second magnetic piece having a polarity different from the polarity of the first magnetic piece. The first magnetic piece is a first magnetic strip, and the second magnetic piece is a second magnetic strip. The first magnetic strip is arranged in the Y-axis direction, and the second magnetic strip is arranged in the X-axis direction. A third magnetic strip and a fourth magnetic strip are further included.
