Modular Autonomous Air and Road Vehicle

Abstract

The modular autonomous air and road mobility (AARM) vehicle with Vertical Take-off and Landing (VTOL) capability provides combined air and road mobility solution.

AARM is clean energy powered, modular vehicle, which can be undocked and redocked into road module and air module, providing uninterrupted autonomous mobility between air and road. In addition, the modular design enables: Easy navigation through highly populated areas without the need to accommodate fixed wing aircraft on urban roads. Reduced energy consumption and noise levels in urban roads by not having to carry the air propulsion system into urban areas.

The road and air modules dock with each other through a sensor guided docking and load carrying mechanism (SGDMS), allowing connectivity, command and control. The vehicle can be scaled appropriately to serve: personal mobility, shared car, air taxis, regional air transport, cargo and shipping, defense missions, medical evacuations and air ambulances.
