TRAYANA - The Multi Terrain Ambulance System

Abstract

In​‍​‌‍​‍‌ emergency situations, rapid medical assistance is vital for saving lives but traditional ambulance services, which rely heavily on the road infrastructure, often face challenges when the terrain is difficult, roads are damaged, or the accessibility is limited. To counter these issues, TRAYANA is introduced as a combination of multi-terrain emergency response vehicle that can perform emergency operations through air, water, and land. The innovative vehicle is a VTOL (Vertical Take-Off and Landing) enabled quad rotor configuration powered by a turboshaft engine and features an amphibious operation element with a watertight and buoyant structure as well as a rugged ground traction system for all-terrain mobility. Such a versatile vehicle can operate under tough and unreceptive conditions including mountainous areas, flood zones, river deltas, and off-road areas. The design features a centrally located turboshaft engine that is mechanically connected to four independent rotors thus providing high power, prolonged operation time, and fast refueling. Brushless DC motors together with a buffer battery are used to power the auxiliary propulsion and other onboard systems. A sophisticated navigation and guidance system utilizes GPS, inertial measurement units (IMU), altimeters, and digital compasses to allow accurate flight and smooth handling. Supplementary situational awareness is provided by laser imaging detection and ranging (LiDAR), wind gauges, and barometers thus enabling the system to adapt swiftly to the prevailing environmental conditions. A twin communication system that combines telemetry for long distances and IoT-based 4G/5G connectivity guarantees live monitoring, unmanned control, and uninterrupted healthcare data streaming.
