Research Of The Technology In The Bionic Jumping Robot

The bionic jumping robot has advantages of small volume and light weight. It can overleap obstacles or ditches that exceed several times the height of its own body. The sudden and eruption of jumping motion contribute to avoiding the danger to the robot. Thus, the jumping robot will have a wide range of applications in modern warfare and the space exploration areas. Due to difficulties in techniques, the research of the jumping robot is still at the initial period all over the world right now. The key points of the bionic jumping robot are to realize continuous jumping of adjusting to the posture of jumping and optimality of the jumping height.At first, this paper systematically analyzes the research situation of domestic and foreign jumping robot, and compares the single foot jumping robot with the polypod one. According to the research of the bionic jumping of insect, this paper compares and analyses several biological prototype of insect jumping. Based on the research on bionics and the motion mechanism of insect, this paper will carry out mechanical bionic study and functional bionic research for insects.This paper puts forward a mechanism model of the bionic jumping robot which is corresponding with the motion characteristics of jump insects, carries out the kinematic analysis of the mechanical model actuated by SMAS actuator based on MATLAB-Simulink module, and conducts the dynamics analysis of the mechanical model using Lagrange method. At the same time, the torsional spring, a component storing energies for the robot, is designed and optimized. Many analyzed processes and research conclusions in this paper have referential meaning to the research of continuous jumping robots.Through the performance analysis of shape memory alloy (SMA, a new material), this paper applies SMA springs as a driver of the jumping robot device, and successfully accomplishes the jumping robot’s four-motion cycle of resetting, energy storage, triggering and jumping under the control system. According to the above analysis, a bionic jumping robot physical model has been schemed out. The technical feasibilities of the four-state jumping robot are verified by the experimental facility.
