Search the D&D KM-IT
The hotline allows the decommissioning and dismantlement community to post problems
in a specific decommissioning and dismantlement (D&D) area and get solutions
from the subject matter specialists. Users can also search for previously published
problems and their solutions.
Technology provides information on decommissioning and dismantlement related technologies including robotics
and any associated demonstrations. It provides technology descriptions, benefits,
limitations, and associated links and documents. It also provides vendor information,
technology and demonstration fact sheet reports, and search capabilities.
The custom decommissioning and dismantlement web crawler searches and retrieve information
from decommissioning and dismantlement related websites. The crawler provides the
user with a listing of best-matching web pages, usually with a short summary containing
the document's title or parts of the text.
The mobile system component provides access to important D&D KM-IT features through wireless devices. The D&D community users can access the following modules from their mobile devices: vendor directory, specialist directory, hotline, technology information, picture library, lessons learned and best practices, and the fixative module.
Lessons learned provides a repository of documents published by the decommissioning
and dismantlement community users. This allows them to share their experience with
Best practices provides a repository of decommissioning and dismantlement best practices
documents that the user community can upload to the system.
The video/picture library allows community users to upload decommissioning and dismantlement
technology and demonstration videos and pictures to the decommissioning and dismantlement
KM-IT system. The videos and pictures could then be viewed by the decommissioning
and dismantlement community.
Weekly reports published by the ALARA center include the status of the decommissioning
and dismantlement activities that have taken place at various centers. It includes
the list of ALARA center activities for consecutive weeks. This feature makes the
reports available to the entire decommissioning and dismantlement user community.
The specialist directory provides a directory of decommissioning and dismantlement
experts in different areas along with their contact information. The user can search
the specialist directory by name or by area of interest.
Vendor management provides a directory of decommissioning and dismantlement vendors
along with their contact information.
Collaboration tools provides information-sharing mechanisms such as decommissioning
and dismantlement news, events calendars, links, message boards, and frequently
asked questions (FAQs). This allows the decommissioning and dismantlement community
to interact with fellow users.
The training component provides training videos related to decommissioning and dismantlement
work, ALARA Centers’ training material and custom training for the decommissioning
and dismantlement community.

Named DALER (Deployable Air Land Exploration Robot) after lead researcher, Ludovic Daler, the robotic platform is uniquely capable of both flight and ground locomotion.What’s novel about the DALER platform is that it uses one set of limbs for both modes of transportation. To accomplish this, researchers applied “adaptive morphology” to their robot design. The robot’s wings—termed “whegs”—transform into walking legs after landing.

The robot was designed for flight and the main design challenge was to integrate the ground locomotion capability on the robot without reducing its flight performance. Not having to add an additional structure for a different mode of locomotion curbs the robot’s weight, therefore sustaining its flight capability.This dual use of a single structure is unique for a robot. Most robots are only capable of one mode of locomotion. Those that are capable of two have a separate structure for each mode. The main disadvantage of multi-modal robots is that they cannot have an optimal performance in each mode.Using its whegs, the DALER robot can fly at a speed of 14 m/s, and is capable of flying in winds of up to 12 m/s. But on the ground, the robot moves at a speed of 0.2 m/s and can rotate on the spot at 25°/s.Ground robots that use whegs to move in rough terrains usually have whegs with three or four spokes, whereas the DALER has whegs with two spokes. However, the geometrical parameters of the robot (the swept angle, the tapper ratio, and the length of the limbs) are designed to maximize the ground speed. And the robot can still “walk" with different gaits, move on different surfaces, overcome high obstacles, and navigate in rough terrains.After covering most of the distance by flying, the robot will land and take less than a second to unlock its wings, making it capable of walking across the terrain in order to perform a careful search. The fact that the DALER robot can walk is a huge advantage in this circumstance, as merely hovering or flying low to the ground would not be as effective. But switching back to flight mode isn’t simple for the robot yet. Operational Experience:
