Abstract
Robots epitomize one of the most popular human imaginations that are evolving to become reality in the most pervasive way. Especially with the rise of artificial intelligence, it is more hopeful than ever that robots one day will be the interactive companions with some degree of emotion. A variety of robots in different forms with considerable mobility are available today. Among them, legged robots are the most attractive due to their dexterity, traversal versatility, functional modularity, and locomotive stability. Legged robots like robotic dogs can survey unchartered territories in uncertain environments. In this comprehensive review article, the status quo of this emerging and exciting field and how electronics of various form factors can functionalize them in an unbiased manner are surveyed and discussed. Different accessories currently available for quadrupedal robots, wearable devices potentially integratable with these robots, data management/integration strategies for reliable interfacing, and future outlook are discussed.
