MarkV-A1
From Wikipedia, the free encyclopedia
IDF American Andros EOD robot. This particular model is the MarkV-A1
MarkV-A1 or Mark5-A1 is a bomb disposal robot designed by
Northrop Grumman
for the purpose of handling potential explosives without risking any
lives. It is part of the Remotec ANDROS line, which includes other
robotic EODs (Explosive Ordnance Disposal.) First responders around the
world depend on the MarkV to handle potential hazards and explosives
from outside the danger zone. Typically, police forces and departments
in large cities have a designated bomb squad or unit for the purpose of
handling potential explosives as well as hazardous materials or threats;
and the MarkV is a technological feat that several of these units have
in their arsenal for exactly that reason.
History
The MarkV-A1 was designed and released by Northrop Grumman Corporation in 2004.
[1] Remotec
has worked in conjunction with the United States military for over 25
years in order to safely protect civilians from potential hazards, and
the MarkV-A1 has been one of the primary resources to do so in the past
decade.
[2] While there are other competitors in the remote-controlled bomb disposal, such as the
DRDO Daksh and the
Wheelbarrow
(robot), the MarkV is a modern goliath that is capable of handling and
defusing explosives, as well as hazardous waste and other materials. New
technologies and techniques have led to the extremely useful
Remotec ANDROS
line along with the several customizations for specific purposes.
Today, the MarkV-A1 is used by the Explosive Ordnance Disposal (EOD),
Law Enforcement/SWAT, HazMat and other first responders.
[3] The MarkV-A1 costs about $180,000.
Design
The robot is equipped with the following key features:
[4][5]
- Colour Surveillance camera with light, 72:1 zoom, pan/tilt, low light switching capability
- Gripper with continuous rotate - Many accessories can be added to work with the gripper
- Quick disconnect camera mount
- 24-inch camera extender
- Manipulator arm that can reach up to 8 feet in the air
- 2-way audio system with weatherproof speaker and microphone mounted on the robot
- Powered by 24VDC - Two 65 amp-hr 12VDC spiral-cell batteries
In addition, the MarkV-A1 also comes standard with several mission
mounts and sensor mounts for additional accessories that serve specific
purposes when needed.
In order to operate the Remotec Andros MarkV-A1 has a control unit
that contains a 15-inch LCD screen. In time dependent, the robot can be
operated solely off of visual feedback provided by its cameras. In
total, the MarkV-A1 has four color video cameras, including a camera
mounted on one of the poles protruding from the top of the robot. It
also features several microphones, lights, and an array of other
sensors. The MarkV-A1 can be operated via one of the three following
methods:
[5]
- Fiber optic cable – deployed from the vehicle
- Wireless radio control
- Hard tether cable
The MarkV weighs approximately 800 pounds with only its standard
features, and its extendable camera can reach up to 6 feet in the air.

Mobility
Due
to its size, the MarkV-A1's top speed is only 3.5 mph, but speed is not a
necessity for a bomb disposal robot. It can, however travel up inclines
to about 45 degrees, and has the capability to ascend and descend
staircases. The tread system is designed to traverse difficult terrain
and the quick-release wheels and tracks allow it to be highly versatile,
giving it the ability to clear openings down to 24" and obstacles up to
16" tall, as well as mud and ditches.
Accessories
Oftentimes
first responders, such as EOD, SWAT, law enforcement or HazMat, need
specific accessories that apply to a certain mission. Northrop Grumman
provides several accessories that can be mounted onto the MarkV-A1
before a mission.
The following are some notable accessories:
[6]
- Laser assembly - Helps with aim
- Fiber optic cable reel - This is one method of controlling the
MarkV-A1. Useful if radio signals are being interrupted. The cable can
extend to 2000 feet.
- Camera/Pan tilt assembly - Adds to the capability of the main camera including 360 degree rotation and better depth perception
- Headset assembly - This allows the operator to receive audio feedback from the robot.
- Shotgun - The MarkV-A1 can be mounted with either a modified 12
gauge Franchi 612 for use as an entry or breaching tool, as well as the
Striker 12 shotgun for delivering non-lethal shots
- SL6 mount assembly - Used in conjunction with L6 or L8 grenade launcher
- Claw assembly - Extends the gripper opening by 2 inches
- Window breaker assembly - Delivers a spring-loaded punch with an aluminum block
- Cordless circular saw assembly - Circular saw with its own power supply held in gripper.
- Cordless drill assembly - Drill held in gripper
- Cable cutter assembly - For heavy duty cables, attached to the gripper fingers
