Abstract
With the development of technology and the increase of social demand, mobile robots have gradually become a hot research topic, occupying an important position in robot research. The shape of mobile robots is diverse. Among them, the leg-foot robots represented by four-legged robots have received extensive attention due to their excellent stability, flexible motion performance and excellent carrying capacity. Research has achieved rich results
The main contents and work done in this paper are as follows:Firstly, the four-legged robots are classified according to the characteristics of mechanical structure, and the advantages and disadvantages of various structures are discussed and analyzed. Finally, the joint structure is selected as the design scheme for design. The drawing of 2D drawings was completed in CAD, and the robot was 3D modeled in Solidworks. Secondly, the common gait of quadruped robot is introduced. The characteristics of each gait are analyzed and compared. The diagonal lap is designed. The four-legged robot is modeled by DH method. The trajectory planning, inverse kinematics calculation in Matlab. In addition, the self-designed and built a simple four-legged robot control system, with the K60 series MCU as the core, the digital servo as the driver, adding the Bluetooth serial port module, completed the circuit schematic and PCB schematic drawing. Finally, a simple model of the quadruped robot was built in Adams for simulation test, which verified the correctness of the gait, and then completed the assembly and debugging of the whole device
KEY WORDS:quadruped robot, Solidworks, CAD, D-H method, trotting
