Modular Self-Reconfigurable Robotic (MSRR) schemes are a vital remedy for the developing demand in consumer products, automations and space exploration. The wider factor of usage and self-healing capacity are some of the influencing characteristics of robot for actual-wide application whereas segmental robotics provide an effective remedy with respect to traditional robotics. Researchers have now noted different forms of application and prototyped different systems of robotics whereas concentrating on constraints such as homogeneity, configurability, energy consumption and form factor. Diversified condition of various segmental robotic remedies projected for actual-world application and usage of various actuators and sensors interfacing methods alongside physical optimization of models present potential problems whereas visualizing and identifying the advantages and disadvantages of various approaches to remedies. This research reviews the various self-reconfigurable robotic schemes with a brief overview of history and architecture of the robotic schemes. Later in this contribution, the problems in the design of hardware, control and planning algorithms, mixed hardware and software problems and in its application problems that are underway are critically evaluated with respect to modular self-reconfigurable robotics.
