Abstract

A miniature spider-like Mars flying exploration robot driven by wind and electric field can carry different types of sensors and land on Mars together with large-scale devices such as Mars rovers without the need for additional driving energy to achieve parameter detection. It relates to the field of micro-robot technology. The main body of the detector is a spider bionic foot structure that plays a supporting and attitude control role; the fiber charging system charges multiple fiber filaments so that after being charged, the multiple fiber filaments repel and disperse from each other due to the same charges, and interact with the opposite charges in the Martian atmosphere, so that the fiber filaments can stand upright, increase the resistance area, and prepare for takeoff by relying on the wind field; the attitude control system applies electricity to the bionic foot to enable the bionic foot to flex and extend. The asymmetric flexion and extension of the six bionic feet changes the wind resistance and thus causes the force to change, thereby adjusting the flight direction; the present invention is suitable for miniature spider-like detectors for detecting planets with thin atmosphere and electric field environments such as Mars.
