izing waterborne improvised explosive
devices (WBIEDs).
Since then, RE2's subsea technology
has continued to evolve. In 2020, RE2
received additional funding from ONR
to continue the development of its
underwater system. During this phase,
the RE2 team upgraded the system for
deep ocean use, enabling it to descend
deeper than its standard operating
depth of 300 meters. It also applied its
computer vision and machine-learning
algorithms, RE2 Detect™ and RE2 Intellect™
to the system to enable autonomous
manipulation capabilities. The
system had been teleoperated up until
then, and these upgrades were focused
on providing Navy personnel with the
ability to autonomously perform mine
countermeasure (MCM) missions using
supervised autonomy, which allows a
human operator to provide oversight
during the mission and intervene if
necessary.
In 2021, RE2 branded its underwater
robotic arms RE2 Sapien™ Sea Class.
That same year, the company announced
that it had received $9.5 million from
ONR to create a robotic system for the
autonomous neutralization of underwater
mines for the U.S. Navy. This system,
called the Maritime
Mine Neutralizat
ion Sys tem
(M2NS), uses
RE2 Sapien™ Sea Class arms to precisely
place and attach neutralization devices
to underwater mines and WBIEDs.
" The detection and neutralization of
WBIEDs and other underwater explosives
is a critically dangerous task for
Navy divers. Consistent with our mission
of improving worker safety, the
M2NS will enable the Navy to find and
autonomously neutralize targets in deep
ocean waters, while experienced divers
supervise from a safe distance, " said Jorgen
Pedersen, president and CEO of RE2
Robotics.
Underwater Autonomy Capabilities
The M2NS uses RE2 Detect and RE2
Intellect to enable the precise, autonomous,
and clandestine neutralization of
WBIEDs. RE2 Detect is perception software
that can detect and track objects in
just about any environment. RE2 Detect
leverages multi-modal 2D and 3D imaging
sensors and algorithms that can
adapt to various lighting and environmental
conditions. RE2 Intellect handles
anomalies that are common in unstructured,
outdoor environments, similar to
the way human brains perceive and process
information. Working
together, RE2 Detect and
RE2 Intellect provide
human-like decision processing
capabilities to
control the RE2 Sapien
Sea Class arms as well as the ROV of the
M2NS.
" The M2NS uses RE2 Detect computer
vision software to locate targets underwater,
and RE2 Intellect to autonomously
and precisely place devices on those targets, "
said Dr. Amanda Sgroi, director of
computer vision and autonomy at RE2.
" We have also integrated new sensors to
provide situational awareness and aid
autonomy, allowing the system to navigate
to extended depths in the ocean. "
Electromechanical Design
Along with RE2 Sapien Sea Class arms,
M2NS uses VideoRay's Defender remotely
operated vehicle (ROV), which both
exhibit unprecedented power density.
RE2 Sapien Sea Class arms feature a compact,
strong, electromechanical design
with human-like dexterity (7-functions
per arm). The system is neutrally buoyant,
which means that the system
stays balanced and controllable
at any depth - an essential
feature when grasping
objects. These features
work together to
provide superior
strength and
precision while
With two symmetrical 7-function arms, RE2 Sapien Sea Class provides human-like dexterity in constrained
underwater environments. The closed, sealed design of the RE2 Sapien Sea Class system protects the
electrical system from water ingress and contamination.
