Design and Kinematics Analysis of Locust-Like Jumping Mechanism

Abstract:

The bionic robot is of great value in research and application. In this paper, the jumping mechanism of a jumping robot is designed through imitates locusts’ jumping, which based on the principles of bionics. The model is established according to the physical structure of locusts, and the kinematic analysis of the model is done by using the virtual prototype software, ADAMS. By comparing the influence of different length on the motion, the curve of displacement, velocity, acceleration and other parameters with different length of actuator was given, as well as the position of dead point. Through analysis by using the virtual prototype software, the appropriate length of bar is confirmed. Thus, a feasible scheme for jumping mechanism of jumping robot is provided.

[1] According to locust-like jumping mechanism, four-bar mechanism which imitates the locusts' leg is used on the jumping mechanism. It can keep smooth in the process of jumping.

[2] A three-dimensional model and a virtual prototype model have been set up. The analysis of kinematics of the model which based on ADAMS has been carried on. And the motion curve of actuator has been obtained. The displacement, velocity, acceleration curve of X direction and Y direction has also been obtained. The feasibility of this project has been proved.

[3] Compared with two kinds of length of eighty millimeters and a hundred and five millimeters. When the length is a hundred and five millimeters, the locust can jump highest, and the spatial position is reasonable and beautiful.

[4] By analysis, the dead point position of the jumping mechanism has been located. This position should be avoided in practical applications.
