1. A method for optimizing coverage of a wireless network of a plurality of mobile robots in an environment, wherein each robot comprises an optical sensor module, a microprocessor and a wireless communication module, the method comprising:
receiving, by a first robot in the network, signals from a second robot in the network;
determining, by the first robot based on the signals, that the first robot or second robot do not fulfil a network coverage condition;
selecting, by the first robot, at least two landmarks in the environment; and
performing, by the first robot, a movement based on an angle between the two landmarks with respect to the first robot, so as to improve the network coverage condition.
