Design and Implementation of Bionic Robot Structure Based on Flexible Joints

Bionic flexible joint combines biological joint structure and flexible motion mechanism, which can adjust the joint stiffness to adapt to the environmental changes through the dynamic changes of the external environment and its own load. Bionic flexible joints can realize robot running, jumping and some bionic movements, and can also meet the design of bionic hand, bionic foot robot and other robots, with a wide range of application prospects. This paper mainly introduces the current status of bionic flexible joint robot research, and explores in detail the production of robots through bionic muscles, flexible connecting rods and other structures, including bionic elephant trunk robots, bionic manipulators and bionic spider robots, etc., and also analyzes the effectiveness of the design of these robots, to provide ideas and methods for the future development of bionic flexible joints. With the development of technology, bionic flexible joints will move to more fields and have great research value.
