Abstract: Modular kinematic steering device, for installation on at least a first module and module of a system of modular vehicles, each module including at least two axes, for each axis, a kinematic steering mechanism adapted to move wheels connected to the axis, a rudder for controlling the kinematic steering mechanism, arranged transversely relative to the axes, the rudder constrainable to the mechanism to transmit rudder motion to the wheels by the mechanism, the rudder defining a variable steering ratio relative to each axis, a mechanism locking device, to make one of the axes a fulcrum rotation of the rudder rigidly connecting the mechanism with the rudder, wherein the first module includes a first rudder having first and second distal ends and the second module includes a second rudder having first and second distal ends, and the distal ends countered and/or counter-shaped to be rigidly connected to each other.

Abstract: An apparatus and system for: combining independent driving vehicles into a single assembly for condensed, efficient, variable capacity transportation on common routes; and for separating into independent vehicles for flexibility on diverse routes. Connection logistics are exchanged locally via line of sight optical channel. Retractable coupling and mated coupling on opposing ends of the vehicles provide multiple degrees of freedom (DOF) to accommodate misalignment during initial dynamic engagement, and lock as rigidly coupled assembly with zero DOF. Mating vehicles' doors open during transit, permitting inter-vehicle movement and consolidation of passengers en route to urban locales, and release of empty vehicles. On return, independent vehicles combine to dense passenger vehicles from urban locales for redistribution of passengers in individual vehicles that later separate for diverse destinations.
