The IDF is testing various types of Israeli built
unmanned ground vehicles, among them, autonomous navigating
robotic vehicles used for security missions and a portable robot
designed to support infantry units in urban warfare.
At AUSA Winter symposium, March
2007 Elbit Systems unveiled its lastest UGV known as the
Versatile, Intelligent and Portable Robot (VIPeR). This robot
is designed to support infantry forces in combat operations.
The company developed the prototype version under an Israel
Ministry of Defense Resrearch & Development Directorate
(DRDD) funding and supplied several systems for evaluations
by the IDF.
The
small robot which has exceptionally high mobility in urban terrain,
based on a new, patented integrated wheeled/track system developed
by Galileo
Mobility Instruments Ltd., powered by two electrical motors,
and a "scorpion tail" which elevates the payload and
stabilizes the platform, enabling the vehicle to rapidly advance
and maintain a steady course of movement over rough terrain.
(view a
video of the prototype developed by Galileo). In handling
obstacles, it is climbing steps or crawling into confined subterranean
spaces and caves. With
compact dimensions and only about 11 kilograms weight and 30x40
centimeters size (excluding the tail) the new robot can fit
into the soldier's backpack and become a standard equipment
of future infantry units. Initial users will most probably be
the Special Forces but eventually the IDF plans to field VIPeRs
with its infantry platoons. The new robot can be equipped with
a standard suite of visual and acoustic sensors and could also
mount various effectors, such as a probe, pistol, 9mm mini-Uzi
or grenade launcher, or a more capable electronically initiated
light weapon (such as a "metal storm" launcher.
Unmanned Patrols
Unlike the ambitious US plan to develop and deploy
highly autonomous combat robots as part of the FCS program,
the Israeli approach is more pragmatic, considering the contributions
of such autonomously navigated vehicles in rather limited, mission-specific
tasks. These will initially include perimeter security and border
patrols and could later be enhanced to specific roles in force
protection. In 2006, the IDF conducted an operational test of
several unmanned systems, designed to conduct partly autonomous
security and patrol missions, as part of border and security
operations along the separation zones between Israel, the west
bank and Gaza strip. The IDF tested several locally developed
systems, including the Guardium,
developed by IAI, AvantGuard,
developed by Elbit. The Israeli MOD is pressing IAI and Elbit
to join forces and harness their combined resources in the UGV
field, to offer a cost effective, partly autonomous security
system to be based on UGVs, that could relieve some of the pressure
from the troops engaged with routine security operations along
the country's borders and securing the perimeters of military
bases and installations. Some defense analysts argue that the
abscence of such systems actually triggered the latest Lebanon
War in 2006, as Hezbollah guerillas ambushed an IDF patrol killing
four soldiers and abducted three from one of the disabled vehicles.
Such missions could be effectively performed by unmanned vehicles
without putting human soldiers in danger.
UGVs
are part of a comprehensive unmanned ground system, based on
the Tomcar chassis, a locally built off-road recreational vehicle,
equipped with autonomous navigation, and obstacle sensing and
avoidance sensors which both feed the control system. The vehicle
can travel autonomously from point to point, following a pre-planned
mission, employing its video and acoustic sensors to monitor
a specific sector, and investigate objects of interest. The
vehicle can negotiate various scenarios, with pre-planned responses,
with or without human intervention. Such capabilities have already
matured at Elbit in other programs. According to Tal Yeshaya,
Head of Elbit Ground Systems, Israel, the company could utilize
its robotic vision, obstacle detection and avoidance capabilities
gained by its subsidiary ElOp subsidiary, through the development
of laser radar obstacle avoidance capability for helicopters,
which have now matured into the LORD system. When deployed,
such robotic vehicles will become "triggers" which
could discriminate between innocent and peaceful activities
along the perimeter, to hostile or suspicious actions, based
on the target's responses.

As the vehicle performs its mission, its operations are constantly
monitored at the command post, where human operators are standing
by to intervene when required.
According to Yeshaya, one of the most critical tasks for such
system is the creation of "remote situational awareness",
where the remote vehicle can accurately "paint" a
realistic and comprehensive situational display. Elbit is introducing
several new capabilities to provide such capabilities, including
the development of a hemispherical display, based on several
video cameras covering 360 degrees. The images generated by
each camera are automatically superimposed and "sewed"
to create the digital, hemispheric picture which is transmitted
back to the command post. Signal processing of a continuous
sequence of such images enables more advanced capabilities,
such as motion detection, object and obstacle tracking, etc.
This hemispheric view also enables the vehicle and operator
to point the main payload to investigate specific targets of
interest. These capabilities were also implemented by the company
in a parallel program, developed to enable tank and AFV crews
to maintain full situational awareness while safely operating
inside the vehicle, under the armor protection. Similar to the
UGV application, this program also integrates sensors, external
sensors and remotely operated systems to enable human operators
to effectively conduct operations without maintaining direct
visual or physical contact with the target.
