robotics
Robotics is an interdisciplinary branch of computer science and engineering. Robotics involves design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrat ...

Description
Tesla designed this system for use in prospecting and discerning the location of underground mineral structures through the transmission of mechanical energy through the subsurface. Data from reflected and refracted signals can be analyzed to deduce the location and characteristics of underground formations. Additional non-mechanical responses to the initial acoustic impulses may also be detectable using instruments that measure various electrical and magnetic parameters. Such predicted responses would--at least--take the form of induced electric and magnetic fields, telluric currents, and changes in earth conductivity.
The electromechanical oscillator was originally designed as a source of
isochronous
A sequence of events is isochronous if the events occur regularly, or at equal time intervals. The term ''isochronous'' is used in several technical contexts, but usually refers to the primary subject maintaining a constant period or interval ( ...
oscillator
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum ...
is called ''isochronous'' if the frequency is independent of its amplitude. An
electromechanical
In engineering, electromechanics combines processes and procedures drawn from electrical engineering and mechanical engineering. Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems ...
device runs at the same rate regardless of changes in its drive force, so it maintains a constant
frequency
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is eq ...
Surface waves
In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at th ...

Shear waves
In physics, a transverse wave is a wave whose oscillations are perpendicular to the direction of the wave's advance. This is in contrast to a longitudinal wave which travels in the direction of its oscillations. Water waves are an example of t ...
