Fig. 9 is a diagrammatic illustration of the system in its preferred form. Referring to fig. 1 and fig. 2, A may designate any type of vessel or vehicle which is capable of being propelled and directed, such as a boat, a balloon or a carriage. It may be designed to carry, in a suitable compartment B, objects of any kind, according to the nature of the uses to which it is to be applied. The vessel, in this instance a boat, is provided with suitable propelling machinery which is shown as comprising a screw propeller C, secured to the shaft of an electro-magnetic motor D, which derives its power from storage batteries EEEE. In addition to the propelling engine or motor the boat carries also a smaller steering motor F, the shaft of which is extended beyond its bearings and provided with a worm which meshes with a tooth ed wheel G. This latter is fixed to a sleeve b, freely movable on a vertical rod H, and is rotated in one or the other direction according to the direction of rotation of the motor R. The sleeve b on rod. H is in gear through the cog wheels H' and H" with a spindle G' mounted in vertical bearings at the stem of the boat and carrying the rudder F¹. The apparatus controlling the operation of both the propelling and steering mechanisms involves, primarily, a receiving circuit which, for reasons before stat ed, is preferably both adjusted and rendered sensitive to the influence of waves or impulses emanating from a remote source, the adjustment being such that the period of oscillation of How does it..
