The Thrusters are the vehicle’s propulsion system. This is a swerve drivetrain. Each of the four thrusters is placed at the extreme Pylon tips of the X Hull. In any configuration, they are responsible for steering and torque output. The original concept is for ground travel but they are interchangeable for amphibious, aerial, tracked or any combination or future adaptation. In its standard setup, it is an omnidirectional ATV.
A good example of this is the system developed by Protean Electric. It is a self-contained hub mounted axial flux drive motor with a high torque Z axis steering motor. The AR uses a direct drive steering motor since it has a 1:1 steering ratio. There is no suspension within a Thruster as its only duties are propulsion and vector.
Visually, the four Thrusters arrangement is similar to the front end of a Spinner from the 1982 movie Blade Runner. They are positioned for ease of maintenance and are hot-swappable. It is not intended to be a high speed vehicle so ultimate maneuverability is the goal. A few more examples are:
