IEEE/SICE International Symposium on System Integration

In ground-view object change detection, the recently emerging mapless navigation has great potential to navigate a robot to objects distantly detected (e.g., books, cups, clothes) and acquire high-resolution object images, to identify their change states (no-change/appear/disappear). However, naively performing full journeys for every distant object requires huge sense/plan/action costs, proportional to the number of objects and the robot-to-object distance. To address this issue, we explore a new map-based active vision problem in this work: “Which journey should the robot select next?” However, the feasibility of the active vision framework remains unclear; Since distant objects are only uncertainly recognized, it is unclear whether they can provide sufficient cues for action planning. This work presents an efficient simulator for feasibility testing, to accelerate the early-stage R&D cycles (e.g., prototyping, training, testing, and evaluation). The proposed simulator is designed to identify the degree of difficulty that a robot vision system (sensors/recognizers/planners/actuators) would face when applied to a given environment (workspace/objects). Notably, it requires only one real-world journey experience per distant object to function, making it suitable for an efficient R&D cycle. Another contribution of this work is to present a new lightweight planner inspired by the traditional multi-armed bandit problem. Specifically, we build a lightweight map-based planner on top of the mapless planner, which constitutes a hierarchical action planner. We verified the effectiveness of the proposed framework using a semantically non-trivial scenario “sofa as bookshelf”.

The purpose of this study is to analyze the health and power quality analysis of motors installed at different blocks of Johar Town Lahore installed by Water and Sanitation Authority (WASA) Lahore. Induction motors are the most important components of industries due to their cost-effectiveness, robustness and high efficiency. However, these motors are prone to some mechanical and electrical faults with time. Most of the faults are due to mismanagement of power and load variations. Usually, health monitoring and quality analysis of induction motors is laborious work. This study was conducted by keeping in mind the most widely used standards of the International Electro-technical Commission (IEC) and the Institute of Electrical and Electronics Engineer (IEEE). To enhance the effectiveness of the electrical systems, a detailed inspection and knowledge are needed for every power system. This technique involves taking measurements from motors in different states i.e. rest, transient and steady. The comparison of the results on different parameters with the help of graphical data is presented in this study for the safe and economical use of machines. The study covers only seven motors out of 596 installed motors at tube well sites in the city of Lahore covering almost 8 million people. There is no existing system to analyze the performance, efficiency and health of these motors. This study may be helpful in quality assurance and save from critical failure that tends to disturb the water supply system. It can also beneficial of saving the cost of repair and plant's down time. It may be recommended to analyze thoroughly the remaining tube well motors for the beneficial of WASA water supply system. © 2023 IEEE.

In this paper, we propose an optimization based SLAM approach to simultaneously optimize the robot trajectory and the occupancy map using 2D laser scans (and odometry) information. The key novelty is that the robot poses and the occupancy map are optimized together, which is significantly different from existing occupancy mapping strategies where the robot poses need to be obtained first before the map can be estimated. In our formulation, the map is represented as a continuous occupancy map where each 2D point in the environment has a corresponding evidence value. The Occupancy-SLAM problem is formulated as an optimization problem where the variables include all the robot poses and the occupancy values at the selected discrete grid cell nodes. We propose a variation of Gauss-Newton method to solve this new formulated problem, obtaining the optimized occupancy map and robot trajectory together with their uncertainties. Our algorithm is an offline approach since it is based on batch optimization and the number of variables involved is large. Evaluations using simulations and publicly available practical 2D laser datasets demonstrate that the proposed approach can estimate the maps and robot trajectories more accurately than the state-of-the-art techniques, when a relatively accurate initial guess is provided to our algorithm. The video shows the convergence process of the proposed OccupancySLAM and comparison of results to Cartographer can be found at https://***/4oLyVEUC4iY. © 2022, MIT Press Journals.

Induction motors comprise more than 90 percent of the industrial load. With time, Induction motors are prone to losses. To save energy consumption, predictive maintenance of motors must be carried out at regular intervals. The industrial monitoring and automation lab has developed state-of-the-art motor test bench facility which is completely automated using LabView - a widely used industrial software. The manual methods of motor testing are not only hectic but also unreliable. A systematic approach has been adopted to measure and analyze various parameters of the induction motor, which will help us to identify key performance factors. This work is towards the development of a high performance motor test bench facility for industrial load. In its current state it can measure up to 15 hp induction motors and perform the tests such as No-Load Test, Full-Load Test, Locked-Rotor Test, Temperature Rise Test, DC Winding Test etc. © 2023 IEEE.

A Framework for Centralized Traffic Routing in Urban Areas 33

A Framework for Centralized Traffic Routing in Urban Areas

Dealing with the ever-increasing demand for traffic management is one of the main challenges of the 21st century. The issue is much more apparent in urban areas during rush hours. Traffic congestion causes economic losses due to delays and increased fuel consumption and, on top of that, is a major health risk. Intelligent centralized traffic routing is an important concept aiming at reducing traffic congestion in urban areas by more effectively utilizing road networks. In this demo, we present a framework that, in a nutshell, integrates techniques for intelligent centralized traffic routing into the well-known SUMO simulator, so these techniques can be evaluated in realistic settings on real/realistic datasets. In particular, the framework automatically identifies "problematic" urban regions by analyzing historical traffic data, then simplifies the road networks by precomputing promising routes (for each considered traffic flow), and finally, leverages a planning-based approach to generate routes. Our framework is evaluated on a real dataset from Dublin's metropolitan area. © 2024 International Joint Conferences on Artificial Intelligence. All rights reserved.

Automated driving systems are an integral part of the automotive industry. Tools such as Robot Operating System and simulators support their development. However, in the end, the developers must test their algorithms on a real vehicle. To better observe the difference between reality and simulation–the reality gap–digital twin technology offers real-time communication between the real vehicle and its model. We present a low fidelity digital twin generator and describe situations where automatic generation is preferable to high fidelity simulation. We validate our approach of generating a virtual environment with a vehicle model by replaying the data recorded from the real vehicle. © 2024 The Authors.
