Nowadays, design, development, and motion planning of a mobile robot explore research areas in the field of robotics. Mobile robots have an extensive area of applications in various fields like space exploration, military application, industrial use, and many more. Hence, the design and development of a mobile robot is a crucial part of the above application. Among all the mobile robot, the quadrupedal robot is a legged robot, which is superior to wheeled and tracked robot due to its potential to explore in all the terrain like the human and animal. In this paper, the survey concentrates on various design and development approaches for the quadrupedal robot, and environment perception techniques are discussed. Besides, Spot is one of the most advanced and intelligent quadrupedal robots. The performance of each quadruped robot and the future outline are provided in details.

如今，移动机器人的设计、开发和运动规划探索了机器人领域的研究领域。移动机器人在太空探索、军事应用、工业应用等各个领域都有广泛的应用领域。因此，移动机器人的设计和开发是上述应用的关键部分。在所有的移动机器人中，四足机器人是一种腿式机器人，由于它具有在人类和动物等所有地形中进行探索的潜力，因此优于轮式和履带式机器人。在本文中，调查集中于四足机器人的各种设计和开发方法，并讨论了环境感知技术。此外，Spot 是最先进、最智能的四足机器人之一。
