MOM-TAGD - Modular, Multi-Tasking, Autonomous, Ground-Vehicle with Drone

Robotic and Drone Defense of an Urban Environment

(Currently in Design)

Introduction

The following is one of several scenarios that are well suited for the combined AGV/Drone system known as MOM-TAGD (Modular, Multi-Tasking, Autonomous, Ground-Vehicle with Drone). Other missions include:

Jungle - Enemy Force Interdiction

Tree Line, Beach Defense

Base Security and Threat Interdiction

ISR

Electronic Warfare

ECM Dome Over Friendly Ground Force.

As MOMTAGD is modular in design the same AGV and Drone combination can be used for each of the above identified missions. To change missions, it is only necessary to swap out preloaded mission specific modules.

MOMTAGD is an open architecture system that is able to be networked and interoperable with satellites. In “Broken Arrow” mod the system can be switched to autonomous navigation and operation not dependent on communications with satellite-based GPS.

The overall design philosophy of the MOMTAGD system is to house intelligence at the base site and to allocate functionality in the field units on an ‘as needed’ basis. That is, once loaded with their mission, the robots and drones will perform mission tasks using on-board intelligence, without the need to contact the main source of intelligence or overhead satellites.

 

Scenario – Robotic and Drone Defense of an Urban Environment

Frame – Defense of Manama, Bahrain (Fictional)

Manama was chosen because of its size, 175,000 people (medium sized) its economic importance and its vulnerability from land, sea and air. Choosing a medium sized city allows the reader to scale up or down as needed. The operating assumption is that we be allowed access to the area before a conflict occurs.

Pre-deployment - The autonomous land vehicle component "ConVehs" (Container Vehicles) will be manually pre-driven around their assigned perimeters in order to set an internal basic map. This is a preferred action but not required.

Alert – There is an initial attack outside of the city from land, sea and air; followed by an armed invasion by overwhelming numbers. The assumption is that perimeter defenses have been breached and an invasion ground force is entering the heart of the city.

Deploy – Upon initiation by a human operator autonomous Container Vehicles (‘ConVehs’) will deploy from pre-positioned, camouflaged, locations throughout the city. The assumption is that the streets (while wide and modern) will be littered with debris and damaged vehicles. The ConVehs will be tracked and suspended so as to overcome or go around large obstacles.

 

(Note: ConVehs will use standard, off-the-shelf remotely controlled vehicle platforms that are modified to accept autonomous navigation and mission specific modules.

The ConVeh navigation will be based on a combination of, pre-programing, inertial navigation, internal map reading, obstacle avoidance, geographic marker recognition and GPS (if available). A ‘difference engine’ will determine which method is currently most accurate. As the ConVehs will only need to deploy within a two square kilometer area and navigate within 2 meters of their intended position, navigation will be basic and will not require artificial intelligence.)

As the ConVehs circumnavigate their two Kilometer circuit, they will release their DAADS (Detached, Autonomous, Attack, Drones). Once released, DAADS will fly to the closest building structure and attach their LTSAM (Limited Time Stationary Attack Mechanism) devices 10 Meters above the street. Each LTSAM will contain an explosive device similar to a Claymore mine. After attaching the LTSAMS to a walled vertical surface; DAADS will then fly back to the ConVeh mother vehicle. They may be reloaded with LTSAMs as needed.

The front and all sides of the LTSAMs will be covered with a cloaking material. One of many choices for the cloaking material would be the cloak from Canada’s HyperStealth Biotechnology Corporation.

    

Once attached to the building, the cloaked LTSAMs  will wait for activation orders from the Command Center. (The field commander has the authority to activate the LTSAMs.)

Combat – Once activated the LTSAMs will activate their sensing and triggering mechanisms. The sensors may be simple motion sensors, FLIR, or LIDAR as the end user chooses. Once activated by the proximity of aggressors, the LTSAMs would shower the enemy troop with a lethal spray of debilitating shrapnel.

(Note: A time delay setting, based on the physical proximity of the lead enemy element may be employed to generate a ‘Trapping Effect’. This would allow the enemy to advance deeply into the group of LTSAMs before any of them activated.)

 

Observations and Measures – During and after the engagement, a cloaked Observer LTSAMs (OLTSAMs) would remain in position to evaluate the effectiveness of the attack on the hostiles. A small LCD camera would send real time results back to central command. As an alternative, the OLTSAM unit will have the capacity to store its information internally for later physical retrieval.

 

Post Combat – LTSAMs are designed explode leaving only small bits of themselves. Any LTSAMs that fail to detonate will become inert within the specified time period as the binary explosive is designed to become predictably stable. They will remain cloaked and difficult to detect by an enemy force. If desired, each LTSAM can be equipped with a locator beacon for later retrieval. The beacon can remain inactive until activated by friendly forces.

 

Peacetime – After their mission, The DAADS, will fly the reverse route from their deployment and when close to the ConVeh vehicles; they will home in on the ConVeh's landing signal. Approach and landing will be controlled by the ConVeh. The DAADS are programmed to return to the ConVeh vehicles which are programmed to return to their home bases. Having previously made a complete circuit, the ConVehs will easily navigate back to their base stations.
