ABSTRACT Model Based Systems Engineering (MBSE) has been a dominant methodology for defining and developing complex systems; however, it has not yet been paired with cutting-edge digital engineering transformation. MBSE is constrained to represent a whole system, but lacks other capabilities, such as dynamic simulation and optimization, as well as integration of hardware and software functions. This paper provides the key elements for developing a Smart MBSE (SMBSE) modeling approach that integrates Systems Engineering (SE) functionality with the full suite of other development tools utilized to create today’s complex products. SMBSE connects hardware and software with a set of customer needs, design requirements, program targets, simulations and optimization functionalities. The SMBSE modeling approach is still under development, with significant challenges for building bridges between conventional Systems Engineering methodology, with additional capabilities to reuse, automate
Abstract This paper presents the development of a transmission-in-the-loop (TiL) experimentation system. In this TiL experimental setup, the input side of the transmission is controlled by a dynamometer emulating the engine, while the output sides of the transmission are controlled by two dynamometers emulating the wheels and vehicle. The models emulating these vehicle components are required to possess sufficient fidelity to simulate engine torque pulse (ETP) and wheel slip dynamics while being computationally efficient to run in real-time. While complex engine and tire models exist in the literature that accurately capture these dynamics, they are often too numerically stiff for real-time simulation. This paper presents the system level details of such a TiL setup, and the modeling concepts for the development of high fidelity real-time models of the engine and tire dynamics for use in this experiment. Parameters of the engine model are identified using experimental data. Vehicle
ABSTRACT The objective is to develop a human-multiple robot system that is optimized for teams of heterogeneous robots control. A new human-robot system permits to ease the execution of remote tasks. An operator can efficiently control the physical multi-robots using the high level command, Drag-to-Move method, on the virtual interface. The innovative virtual interface has been integrated with Augmented Reality that is able to track the location and sensory information from the video feed of ground and aerial robots in the virtual and real environment. The advanced feature of the virtual interface is guarded teleoperation that can be used to prevent operators from accidently driving multiple robots into walls and other objects
ABSTRACT This paper discusses the design and implementation of an interactive mixed reality cockpit that enhances Soldier-vehicle interaction by providing a 360-degree situational awareness system. The cockpit uses indirect vision, where cameras outside the vehicle provide a video feed of the surroundings to the cockpit. The cockpit also includes a virtual information dashboard that displays real-time information about the vehicle, mission, and crew status. The visualization of the dashboard is based on past research in information visualization, allowing Soldiers to quickly assess their operational state. The paper presents the results of a usability study on the effectiveness of the mixed reality cockpit, which compared the Vitreous interface, a Soldier-centered mixed reality head-mounted display, with two other interface and display technologies. The study found that the Vitreous UI resulted in better driving performance and better subjective evaluation of the ability to actively
ABSTRACT Vehicle design today takes longer than it ever has in the past largely due to the abundance of requirements, standards, and new design techniques; this trend is not likely to change any time soon. This paper will explore how advancements in gaming engines can be leveraged to bring realistic visualization and virtual prototypes to the beginning of the design cycle, integrate subsystems earlier in the design, provide advanced simulation capabilities, and ensure that the final design not only meets the requirements but is fully vetted by stakeholders and meets the needs of the platform. The Unreal Engine and Bravo Framework can be used to bring this and more to vehicle designs to reduce design churn and bring better products to market faster. Citation: A. Diepen, O. Vazquez, A.

ABSTRACT This research proposes a human-multirobot system with semi-autonomous ground robots and UAV view for contaminant localization tasks. A novel Augmented Reality based operator interface has been developed. The interface uses an over-watch camera view of the robotic environment and allows the operator to direct each robot individually or in groups. It uses an A* path planning algorithm to ensure obstacles are avoided and frees the operator for higher-level tasks. It also displays sensor information from each individual robot directly on the robot in the video view. In addition, a combined sensor view can also be displayed which helps the user pin point source information. The sensors on each robot monitor the contaminant levels and a virtual display of the levels is given to the user and allows him to direct the multiple ground robots towards the hidden target. This paper reviews the user interface and describes several initial usability tests that were performed. This research

ABSTRACT As technology continues to improve at a rapid pace, many organizations are attempting to define their place within this modern age and the Department of Defense (DoD) is no exception. The DoD’s primary focus on modernization ensures that its design, development, and sustainment of systems demonstrate unparalleled strength that outpaces our adversaries and continue to solidify our position quickly and efficiently as the world’s mightiest through fundamental change. Digital Engineering (DE) is the foundation of that fundamental change. Speed-to-Warfighter, reliability, maintainability, resiliency, and performance are all improved through DE techniques. Accelerating technical integration by connecting once isolated data to a digital thread encompassing all domains, and further facilitating the evolution of the traditional approach/processes into an effective DE strategy. DE’s goal supports a reduction of inefficient process/procedures/communications that traditionally can yield
ABSTRACT Operation of a virtual vehicle in order to perform dynamic evaluation of the design can be achieved through the use of augmented reality combined with a simulator. Many uses of virtual reality involve the evaluation of component packaging in a static although interactive manner. That is, the virtual reality (VR) participant can interactively view the virtual environment and perform some minor interactions such as toggling through alternative CAD models for comparison or changing the viewing position to another seat. The immersive 3D simulator system described in this paper enables the VR participant to perform operational tasks such as driving, gunnery and surveillance. Furthermore, this system incorporates augmented reality in order to allow the mixture of the virtual environment with physical controls for operating the virtual vehicle
Crew Station design in the physical realm is complex and expensive due to the cost of fabrication and the time required to reconfigure necessary hardware to conduct studies for human factors and optimization of space claim. However, recent advances in Virtual Reality (VR) and hand tracking technologies have enabled a paradigm shift to the process. The Ground Vehicle System Center has developed an innovative approach using VR technologies to enable a trade space exploration capability which provides crews the ability to place touchscreens and switch panels as desired, then lock them into place to perform a fully recorded simulation of operating the vehicle through a virtual terrain, maneuvering through firing points and engaging moving and static targets during virtual night and day missions with simulated sensor effects for infrared and night vision. Human factors are explored and studied using hand tracking which enables operators to check reach by interacting with virtual components

From the past few years, there is a pressing need for implementation of automatic in-vehicle safety systems to avoid vehicle crashes and fatalities. Development of autonomous emergency braking systems (AEBS) to detect and avoid collisions in such critical moments is of paramount importance. In this paper, AEBS is developed for a four-wheeler system that aims to detect vehicles and controls the ego vehicle based on the expected stooping distance (ESD). This control system aims to react based on the real-time relative distance & speed of the ego vehicle to actuate appropriate braking force. Control systems developed in Altair Activate are co-simulated with CARLA, a virtual reality simulator for autonomous driving research. Various scenarios including low and high-speed car to car motion, urban high and low traffic density environments are simulated to study the robustness of the control system. Further, studies are conducted to evaluate the effectiveness of the systems by varying the
Direct debugging of a vertical takeoff and landing (VTOL) fixed-wing aircraft’s control system can easily result in risk and personnel damage. It is effectively to employ simulation and numerical methods to validate control performance. In this paper, the attitude stabilization controller for VTOL fixed-wing aircraft is designed, and the controller performance is verified by MATLAB and visual simulation software, which significantly increases designed efficiency and safety of the controller. In detail, we first develop the VTOL fixed-wing aircraft’s six degrees of freedom kinematics and dynamics models using Simulink module, and the cascade PID control technique is applied to the VTOL aircraft’s attitude stabilization control. Then the visual simulation program records the flight data and displays the flight course and condition, which can validate the designed controller performance effectively. It can be concluded that the designed VTOL fixed-wing aircraft control visual simulation

For almost as long as it’s been a concept, NASA has been on the cutting edge of virtual reality (VR) technology. However, the space has seen a renaissance since the bulky headsets of the 1990s. Several high-profile companies now use VR for immersive video games and virtual chat rooms, but, to some, this technology has a use beyond entertainment
More pixels! This is a major trend in the display industry. The benefits of 8K or higher resolution TVs may be debatable. For eye catching applications such as AR/VR glasses, more and therefore smaller pixels are required for technical feasibility. Screen door effects and pixel inhomogeneities are easily visible and disturbing for the user on displays that sit closely to the viewer’s eye. μ-LEDs are considered an innovative technology for very high resolutions with pixel sizes of less than 10 μm and equally small pixel pitches. In general, they have the potential to be a groundbreaking display technology – provided production challenges can be solved. Just like OLED displays, μ-LEDs are an emissive display technology, i.e., each single subpixel is in itself a light source. Luminance and color variations between the individual pixels are likely. As this strongly influences the visual quality of the displays, a quality control and calibration of the displays is necessary not only in the
A research team from the National University of Singapore (NUS) Faculty of Science, led by Professor Liu Xiaogang from the Department of Chemistry, has developed a 3D imaging sensor that has an extremely high angular resolution — it can distinguish points of an object separated by an angular distance, of as little as 0.0018°. The sensor operates on a unique angle-to-color conversion principle, allowing it to detect 3D light fields across the X-ray to visible light spectrum
Thanks to artificial intelligence (AI), augmented reality (AR) has long shaped product development across a variety of areas, including the medtech industry.

To do this, medical practitioners use recommendations provided by AI, which in turn draws on a broad digital database

The researchers from the University of Cambridge have developed an algorithm, which gives an accurate measurement of tree diameter, an important measurement used by scientists to monitor forest health and levels of carbon sequestration. The algorithm uses low-cost, low-resolution LiDAR sensors that are incorporated into many mobile phones, and provides results that are just as accurate, but much faster, than manual measurement techniques
Technology capable of replicating the sense of touch — also known as haptic feedback — can greatly enhance human-computer and human-robot interfaces for applications such as medical rehabilitation and virtual reality. A soft artificial skin was developed that provides haptic feedback and, using a self-sensing mechanism, has the potential to instantaneously adapt to a wearer’s movements
Recent events have shown that challenges to the global status quo can arise rapidly, making it imperative that military manufacturers remain agile and prepared to meet new circumstances as they emerge. As author Jim Pattison succinctly stated: “No matter what business you are in, there is change, and it's happening pretty quickly.” The challenges posed to military manufacturers include shorter design and production timetables, the need for greater efficiency in parts replacement and material usage, and an accelerated time to market; challenges that must be met with every technological tool available. The current revolution in manufacturing driven by digital technologies, is transforming the global production landscape. While artificial intelligence, augmented reality and the Industrial Internet of Things (IIoT) are increasing production efficiency and time to market, 3D scanning still has not been exploited by aerospace and defense manufacturers for its full potential to do the same
Industrial vehicles such as forklifts, cranes and tractors have come a long way in terms of applying technology, enhancing performance with improved operation and safety. With the advancements in computer vision, robotics and artificial intelligence (AI), these vehicles now are equipped with functionality that utilizes information to support and optimize performance. One of the key enablers of these advances is the integration of machine learning (ML) derived platforms and powerful computers, neural processing units and cameras integrated into the digital system. System designers and OEMs can get started with AI and computer vision using just a standard Ethernet camera and a Cortex A35 dual- or quad-core next-generation display. Using the detection and recognition of objects, designers can implement and train neural networks to realize new solutions for process guidance, automation, augmented reality and operator awareness. For example, the dual-core CCpilot V700 from CrossControl can
The way in which businesses, enterprises, industry leaders, and consumers utilize technology for everyday tasks is set to undergo one of the most drastic evolutions ever. Just a few short years ago it was nearly impossible to think any other technology could have a greater impact than networked computers, the Internet, or even mobile computing, but now technologies like artificial intelligence (AI), Internet of Things (IoT) and AR/VR are being hyped more than ever
Despite recent supply-chain disruptions, semiconductor buyers are increasingly spoiled for choice when it comes to chip manufacturers. From a chipmaker’s perspective competing for “sockets” in the next gadget — whether it be a mobile phone a VR headset, or an EV — is a game of speed. As a result, competition among producers continued to reduce product development and delivery times — once years to now a few short months
Rolls-Royce is leading an ambitious decarbonisation strategy, aiming to become a net zero carbon company across their value chain by 2050.
