Swarm-Inspired Cooperative Mapping for Urban Autonomous Navigation2026-26-0635To be published on 01/16/2026
Urban autonomous vehicles today largely rely on individually built maps or centralized cloud services—both rigid under intermittent connectivity and rapid scene changes (construction, pop-up events). Inspired by how ant colonies collectively explore, we introduce a decentralized protocol: each vehicle broadcasts compressed “map particles” embedded with virtual pheromone values that highlight zones of high uncertainty or recent change. Neighboring vehicles incorporate these signals to prioritize sensing and route planning. A lightweight consensus algorithm merges local graphs into a shared dynamic map, resilient to network splits. The result, a bio-inspired SLAM that enables fleets to adapt on the fly to evolving cityscapes, boosting safety, efficiency, and robustness.

Path Planning and Control Strategies for a Semi-Autonomous Light Commercial Vehicle Navigating and Avoiding Static Obstacles in Urban Environments2026-26-0134To be published on 01/16/2026
This paper presents the design and implementation of a Semi-Autonomous Light Commercial Vehicle (LCV) capable of following a person while performing obstacle avoidance in urban and controlled environments. The LCV leverages its onboard 360-degree view camera, RTK-GNSS, Ultrasonic sensors, and algorithms to independently navigate the environment, avoiding obstacles and maintaining a safe distance from the person it is following. The proposed system employs a path planning algorithm that generates a secondary lateral path originating from the primary driving path to navigate around static obstacles. A Behavior Planner is utilized to decide when to generate the path and avoid obstacles, ensuring timely and efficient navigation adjustments. The primary objective is to ensure seamless and safe navigation in environments where obstacles are present. The LCV's path tracking is achieved using a combination of Pure Pursuit and Proportional-Integral (PI) controllers. The Pure Pursuit controller

Mapless Yet Accurate: Trajectory Prediction for traffic agents using online HD Map Reconstruction for Autonomous Driving2026-26-0039To be published on 01/16/2026
Accurate trajectory prediction of traffic agents is vital for enabling safer and more reliable autonomous driving. High-definition (HD) and standard-definition (SD) maps play a critical role in this process by providing detailed lane topology and directional cues essential for forecasting the movement of surrounding traffic agents. However, creating HD maps is both expensive and resource-intensive, often relying on complex SLAM systems and specialized sensors, while SD maps, though more readily available, lack the precision needed for accurate navigation in autonomous driving. In this work, we present a novel framework for trajectory prediction that uses online reconstruction of HD maps using images from vehicle-mounted cameras, offering a more scalable and cost-effective solution. Our method achieves notable improvements in prediction accuracy, especially in scenarios lacking access to pre-built maps. Additionally, we propose a new evaluation metric that emphasizes safety by

Video 2 Scenario: A Novel Method to Generate Edge Case Traffic Scenarios from Dashcam Videos2026-26-0666To be published on 01/16/2026
This paper presents Video 2 Scenario, a systematic and cost-effective method to generate edge case scenarios derived from road events captured in dash camera videos. Current methods for obtaining real-world scenarios rely on supplementary sensor data like LiDAR, GPS and radar, which require expensive sensor setups for data collection. Other scenario generation methods rely on manual effort by human experts, which can be laborious and time-consuming. Our proposed methodology utilizes state-of-the-art deep learning models to extract vehicle trajectories, road layouts and other scenario-specific elements and reconstructs a scenario in the format of simulation scripts. The scripts are then refined by replaying the scenario multiple times in a simulation with attached virtual sensors to minimize the discrepancy between the subsequently obtained simulated video data and the original dash camera video data. The refined simulation scripts ensure that critical edge case scenarios are replicated

ABSTRACT Automatic guided vehicles (AGV) have made big inroads in the automation of assembly plants and warehouse operations. There are thousands of AGV units in operation at OEM supplier and service facilities worldwide in virtually every major manufacturing and distribution sector. Although today’s AGV systems can be reconfigured and adapted to meet changes in operation and need, their adaptability is often limited because of inadequacies in current systems. This paper describes a wireless navigated (WN) omni-directional (OD) autonomous guided vehicle (AGV) that incorporates three technical innovations that address the shortfalls. The AGV features consist of: 1) A newly developed integrated wireless navigation technology to allow rapid rerouting of navigation pathways; 2) Omnidirectional wheels to move independently in different directions; 3) Modular space frame construction to conveniently resize and reshape the AGV platform. It includes an overview of the AGVs technical features

GPS-BASED MOBILITY POWER ANALYSIS OF MILITARY VEHICLES2024-01-331111/15/2024
ABSTRACT Determining the required power for the tractive elements of off-road vehicles has always been a critical aspect of the design process for military vehicles. In recent years, military vehicles have been equipped with hybrid, diesel-electric drives to improve stealth capabilities. The electric motors that power the wheel or tracks require an accurate estimation of the power and duty cycle for a vehicle during certain operating conditions. To meet this demand, a GPS-based mobility power model was developed to predict the duty cycle and energy requirements of off-road vehicles. The dynamic vehicle parameters needed to estimate the forces developed during locomotion are determined from the GPS data, and these forces include the following: the gravitational, acceleration, motion resistance, aerodynamic drag, and drawbar forces. Initial application of the mobility power concept began when three U.S. military’s Stryker vehicles were equipped with GPS receivers while conducting a

Deere advances in-field autonomy22TOFHP08_0108/01/2022
While stereo cameras and computer vision guide Deere's “limited release” 8R autonomous tractor, Bear Flag's lidar tech will augment future machines. Q&A with Deere's Joe Liefer John Deere got “really serious” about autonomy in 2019, according to Joe Liefer, senior product manager of autonomy at John Deere Intelligent Solutions Group. Three years later - after forming an in-house development team and acquiring some tech-startup expertise - the machinery maker revealed a fully autonomous tractor at CES 2022 that it claims is ready for large-scale production. Based on Deere's 8R tractor, the machine combines a TruSet-enabled chisel plow, GPS guidance system, advanced AI and six pairs of stereo cameras that enable 360-degree obstacle detection and distance calculation. The autonomous 8R tractor also continuously checks its position relative to a geofence and is accurate to within less than 1 inch (25 mm), Deere claims. Farmers monitor and control it from a smartphone app.
Positioning to centimeter-level improves agriculture22TOFHP08_0208/01/2022
Precision-navigation approaches that emphasize backward compatibility help farms reap more value from autonomous operations. Precision navigation, which is essential to autonomous machines, is knowing a moving vehicle's absolute and relative position in 3D space accurately, reliably and repeatably. The cost for precision navigation with position information down to the centimeter level has become a far less significant barrier to broad deployment. This price drop has come with enhanced, not diluted, performance. One reason for the cost decrease has to do with the sheer volume of Global Navigation Satellite System (GNSS) receivers on the market. GNSS encompasses the satellite-based GPS used in North America as well as other global positioning systems such as GPS, Galileo, Glonass, BeiDou, NAVIC (former IRNSS) and QZSS.

Vision-Based Collision free technique for Autonomous Navigation of MAV in GPS-denied Environments2022-26-125005/26/2022
The drone-based aerial platform offers various applications such as security and emergency response, delivery, defense, inspection, mapping, film, and entertainment. For safe driving, an automated vehicular navigation system (AVNS) must have a precise location. Although the vehicle location can be retrieved in GPS-friendly surroundings, the positioning accuracy of AVNS is easily reduced in GPS-denied environments (such as suburbs, tunnels, forests, and indoor scenarios). Researchers have already developed various methods to handle UAV navigation in GPS-less environments, such as Visual Odometry (VO) and Simultaneous Localization and Mapping (SLAM). This paper proposes a new Qualcomm Snapdragon referenced visual-inertial odometry (VIO) algorithm for indoor GPS-denied Micro Aerial Vehicle (MAV) navigation. The custom-built MAV is comprised of a hardware platform equipped with a VOXL flight companion computer, PX4 flight controller, pre-calibrated stereo and tracking sensors, a high

Geotagged Visual Localization System for Urban Automated Vehicles2022-01-010103/29/2022
Vehicle localization is one of the fundamental building blocks of Automated Driving Systems. Erroneous localization information may affect the ability of the vehicle to perceive the environment and plan a safe path to the desired destination. Although, high-end satellite navigation systems can provide centimeter-level accuracy, they are limited to applications where there is sufficient satellite signal visibility. One example where signals from navigational satellites might deteriorate is urban canyons which are characterized by high rise, high density residential and commercial buildings. To overcome the limitations of satellite navigation systems, most state-of-the-art localization solutions fuse information from multiple sensors such as GNSS, LiDAR, camera, accelerometer, and encoder with the purpose of creating a full 3D map of the operating environment. Although this approach provides accurate and reliable results, it is bounded in terms of data efficiency and scalability. With

Positional Accuracy of Portable GPS Devices during Different Ride Stages2022-01-099203/29/2022
GPS devices can produce a wealth of data about cyclists’, scooterists’, and other riders’ road paths and route usage. However, prior research has demonstrated that GPS positional accuracy is less reliable for more nuanced roadway positioning, such as which lane a vehicle occupies, as well as within-lane movements, such as acceleration and deceleration⁠. This limitation presents a substantial challenge for crash reconstructionists that may have access to GPS data and require second-by-second positional accuracy to determine such nuanced maneuvers and vehicle positioning in their analysis. The purpose of this study was to examine the positional accuracy of several GPS units during three different ride stages: acceleration, deceleration, and constant speed. The same devices were also tested for stationary accuracy, power cut-off, and simulated impact scenarios. To obtain precise data from GPS units, tests were performed with an electric scooter ridden in rural landscapes with clear skies

Multi-Modal Neural Feature Fusion for Pose Estimation and Scene Perception of Intelligent Vehicle2021-01-018804/06/2021
The main challenge for future autonomous vehicles is to identify their location and body pose in real time during driving, that is, “where am I? and how will I go?”. We address the problems of pose estimation and scene perception from continuous visual frames in intelligent vehicle. Recent advanced technology in the domain of deep learning proposes to train some learning models for vehicle’s series detection tasks in a supervised or unsupervised manner, which has numerous advances over traditional approaches, mainly reflected in the absence of manual calibration and synchronization of the camera and IMU. In the paper, we propose a novel approach for pose estimation and scene recognition with a deep fusion of multi-modal neural features in the manner of unsupervised. Firstly, low-cost camera and IMU are used to extract original visual and inertial data, then the visual and inertial encoders are utilized to encoder the feature of the two modes.

Vehicle-Mounted Integrated Positioning System with Vondrak Low Pass Filter and Multi-Dynamic Constraints in Urban Shaded Environment2020-01-521412/30/2020
The Global Navigation Satellite System (GNSS) alone cannot provide high-precision and continuous positioning information for vehicles. The integration of GNSS with Inertial Navigation Systems (INS) has now been very intensively developed and widely applied in high precision positioning of vehicle and provide continuous position, velocity and attitude. However, the overall performance of low-cost GNSS/MEMS IMU frequently degrades in urban shaded environments. Traditional constraints GNSS/MIMU algorithm based on zero-velocity detection can effectively increase the accuracy of the navigation system, but easily influenced by external factors to false detection. This article aims to introduce a multi-dynamic constraints model as accurate update source for EKF to improve the accuracy of navigation solutions of a vehicle during satellites signal blockages. Firstly, we present a tightly coupled strategy to integrate GPS/BDS and INS by applying extended Kalman filter with 27-states. Then, a

Tethered Drones Improve Cellular and Internet NetworksTBMG-3818812/01/2020
The use of tethered unmanned aerial vehicles (TUAVs) has been modeled as a powerful new tool for improving cellular phone and Internet networks. When employed as flying base stations with a cable connection, multirotor drones could quickly ramp up coverage, increase the efficiency of urban networks, and provide much needed access in remote rural areas.
Jacobs School of Engineering, University of California San DiegoTBMG-3821112/01/2020
Engineering at the University of California San Diego (UCSD) in La Jolla started in 1964 and 1965 with two broad applied science departments: one in the areas of aerospace engineering, solid mechanics, bioengineering and materials and the other in the areas of electronics, information theory, and radio astronomy. In 1997, the School of Engineering was renamed the Jacobs School of Engineering to honor Qualcomm founder and former UCSD engineering professor Irwin Jacobs and his wife.
Collision Detector Mimics Locust SwarmsTBMG-3813612/01/2020
Plagues of locusts, containing millions of insects, fly across the sky to attack crops but the individual insects do not collide with each other within these massive swarms. A team of engineers is creating a low-power collision detector that mimics the locust avoidance response to help robots, drones, and even self-driving cars avoid collisions.

Air Force Technology Tracks “Sporadic E”TBMG-3823812/01/2020
Researchers at the Air Force Research Laboratory (AFRL) in New Mexico have discovered a new way to track and characterize a phenomenon called “Sporadic E” that naturally occurs in the upper atmosphere where large structures of dense plasma form. These plasma structures, which occur at midlatitude locations around the world, disrupt radio frequency (RF) electromagnetic waves (or simply “radio waves”) and impact both DoD and civilian radio systems in positive and negative ways, depending on the application.
“Alexa, Go to The Kitchen and Fetch Me a Snack”TBMG-3801511/01/2020
Wouldn’t we all appreciate a little help around the house, especially if that help came in the form of a smart, adaptable, uncomplaining robot? Sure, there are the one-trick Roombas of the appliance world. But MIT engineers are envisioning robots more like home helpers, able to follow high-level, Alexa-type commands, such as “Go to the kitchen and fetch me a coffee cup.”
Ambient Light Alters Refraction in 2D MaterialTBMG-3801411/01/2020
Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. A two-dimensional array of the material has unique optical characteristics that can be controlled in ambient conditions and under general illumination.
Further Development of Particulate Sensors for Mobile Use with the Aid of a Circuit Board2020-01-163810/05/2020
In the last decade, pollution by particulate matter and its effect on human health has increasingly becoming the focus of public attention. In order to monitor and evaluate particulate pollution, expensive measuring stations were placed at traffic hotspots and other selected locations. The measuring devices often precisely record the particle concentration, but have disadvantages in mobility and for measurements in large-area due to their size and investment costs. A measurement with high temporal and spatial resolution is not possible with these stations. This paper presents a new type of mobile particulate sensor based on the Plantower PMS 7003 particle sensor. In addition to the Plantower sensor, a rechargeable battery and newly developed control electronics are also installed in the particulate sensor. Due to the small size and the low manufacturing costs of the measuring system, mobile usage in higher quantity is possible. In addition, the system can record the geographical
