Description:FIELD
The present disclosure generally relates to the field of an Unmanned Guided Vehicle (UGV) based robotic system for armed forces. More particularly, the present disclosure relates to UGV enhanced to assist troops in counter-insurgency operations, especially for building clearance and hostage rescue.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
In recent decades, armed forces worldwide have encountered a shift in the nature of warfare. In contemporary warfare, armed forces encounter diverse and complex operational environments where enemies often hide in urban or rural buildings, tunnels, culverts, caves, and similar confined areas. Such scenarios pose significant challenges to military units as they necessitate the clearing of these areas to regain control of the terrain while minimizing risks to personnel.
Urban warfare, in particular, presents numerous challenges to military operations. Defence forces are often required to navigate complex, densely populated areas while minimizing civilian casualties. Simultaneously, they must neutralize enemy combatants who blend seamlessly with the local population and employ guerrilla tactics. Traditional approaches to urban warfare can be slow, resource-intensive, and expose soldiers to extreme risks.
In addition to urban warfare, rural and underground settings pose distinct challenges. Adversaries frequently exploit these environments for their defensive advantages and concealment opportunities. Such operations demand specialized training, equipment, and strategies to mitigate the risks associated with these confined and hazardous spaces.
Therefore, there is a need felt in the art for an Unmanned Guided Vehicle (UGV) based robotic system for armed forces that eliminates the above-mentioned drawbacks.
