Unmanned aircraft traction control system without traction rod and intelligent tractor
An unmanned aircraft traction control system without a traction rod and an intelligent tractor relate to the technical fields of aircraft ground motion and man-machine coordination. The traction control system includes an aircraft light identification and induction module, a main sensing system module, an aircraft sound identification and induction module and a control module which are arranged on the tractor.
