Several researchers have revealed the huge potentials of rescue robots in disaster zones. In addition to searching for victims, these\nintelligent machines are also effective in obtaining useful information from the zones. These functions help to optimize the search\nand rescue missions. However, the fact that rescue robots have to operate in risky and dangerous environments necessitates the\nneed for suchmachines to have an efficientmotion control system, which can help themto operate autonomously or with minimal\nhuman control. This paper reviews the use of reliable controllers in enhancing the sensing capabilities of rescue robots. Huge\npotential of sensorless sensing method in the rescue robots are highlighted. It is shown that the use of sensorless sensing method\nenables developer to create simple and cheaper robots for various complex situations. Thus, it is imperative to conduct further\nstudies on how to optimize the operations of robots that lack sensors.
