Module fiducial markers for robot navigation, address markers and the associated robots

A robot, configured for interacting with a module for robot navigation, wherein the module comprises a whole workspace area for robot traveling divided into a plurality of module areas, wherein each module area is provided with a unique address marker, and each module area is internally provided with a first magnetic strip having a polarity of an N pole or an S pole, a second magnetic strip having a polarity different from the polarity of the first magnetic strip and a third magnetic strip having a polarity same as the polarity of the second magnetic strip, the robot comprising:

• a plurality of magnetic induction sensors and an address marker recognition device installed on the bottom thereof;
• wherein the plurality of magnetic induction sensors collect signals of magnetic pieces having different polarities, and the address marker recognition device collects the address marker information,
• wherein the plurality of magnetic induction sensors and the address marker recognition device are connected to a robot controller, and the robot travels to a target module area according to instructions and collected marker information,
• wherein the first magnetic strip has a different length than the second magnetic strip,
• wherein the magnetic strips having the same polarity intersect.
