The automotive advanced driver assistance systems (ADAS) are increasingly sophisticated due to the rapid advancement of intelligent connected vehicle technology. Consequently, higher demands are placed on both hardware infrastructure and onboard systems. To tackle the challenge of achieving complex traffic object recognition on limited hardware resources, a novel multi-sensor feature-level fusion strategy is proposed, which integrates data from millimeter-wave radar and visual sensors. By achieving synchronization of different sensors in both time and space domains, this strategy enhances the accuracy and robustness of traffic object recognition, while also improving computational efficiency and overall system performance. © 2024 SPIE.

Attitude determination is an important part of microsatellite attitude control system. Its determination accuracy directly affects microsatellite's attitude control performance. Hence, a novel attitude determination approach is presented in this work for microsatellites with star sensor and gyros fixed. The factor graph representing the probabilistic graphical model as a bipartite graph is applied to solve the attitude estimation problem. This allows multi-rate, asynchronous, and possible delayed measurements to be incorporated in a natural way. An incremental smoothing algorithm is then proposed to achieve optimal estimation. Simulation results are finally presented to verify that the proposed approach can significantly improve the attitude determination accuracy.

Different articles have published serial communication characteristics measurements for real-time control system (RCS). However, most of them focused on latency time measurements. Articles addressing a specific case with a combination of non-deterministic time elements such as rotary encoder (RE) and serial peripheral interface (SPI) are limited. This paper proposed a method to cope with a non-deterministic time due to the RE pulse timing by using a separate processor to handle pulse signals from the RE and time delay measurements of the SPI signal. It investigated the consumption time of each process, i.e., reading sensor signal, calculating control command, and sending control command. We used a microcontroller instead of a personal or industrial computer since the control system will be embedded in an electric vehicle (EV) for drive-by-wire (DbW) function. We obtained the experimental results of 4.42 mu s and 6 mu s for reading the sensor signal and sending the control command, respectively. The microcontroller required 1.2 mu s to complete a simple control command calculation. The approach presented in this paper can generally be used for sampling time value determination in designing a RCS using the RE as sensor and SPI for sending the control command signals to the actuators. We obtained the appropriate sampling time value of 25 ms. It will be used for designing a feedback controller.

This paper presents a voice-controlled and low-cost design of a practical smart house system (SHS). The proposed system uses to remotely control all digital devices using voice commands, and gives safety by identifying fire and recognizes suspicious movement. It is based on group of sensors, Arduino board, GSM and Bluetooth as a wireless technology to connect system components. Some appliances and sensors are directly associated with the Arduino. These appliances can be effectively controlled by user-friendly mobile interface. The microcontroller can additionally send signals if it identifies any unusual movement. To show the reliability and viability of this framework, devices such as LED lights, temperature, PIR Motion and ultrasonic distance detection sensors are incorporated with the proposed system. The proposed system is shown to be an easily configurable system, sensible, secure, cost effective and required less power comparing with other reviewed systems. Therefore, it is an appropriate and great candidate for the SHS. © 2023 IEEE.

Exoplanet direct imaging using adaptive optics (AO) is often limited by non-common path aberrations (NCPAs) and aberrations that are invisible to traditional pupil-plane wavefront sensors (WFSs). This can be remedied by focal-plane (FP) WFSs that characterize aberrations directly from a final science image. Photonic lanterns (PLs) can act as low-order FPWFSs with the ability to direct some light to downstream science instruments. Using a PL on the SEAL (Santa Cruz Extreme AO Laboratory) high-contrast imaging testbed, we demonstrate (1) linear ranges and (2) closed-loop control. Additionally, we simulate the use of the PL in a multi-wavefront sensor AO system, in which multiple WFSs feed back to the same common-path deformable mirror. Building on previous multi-WFS AO demonstrations on SEAL, we simulate a modulated pyramid WFS to sense aberrations of high spatial order and large amplitude, and the PL to sense low order aberrations including NCPAs. We assess adaptive optics performance in this setting using three different PL wavefront reconstruction algorithms. We also provide a new method to experimentally identify the propagation matrix of a PL, making advanced model-based algorithms practical. This work demonstrates the role of photonic technologies and multi-stage wavefront sensing in the context of extreme AO and high contrast imaging.

One of the crucial processes in the food manufacturing industry is monitoring and measuring the raw products stored in large storage structures, typically called Silos. These procedures are pivotal in dictating the industry's production, quality control, and efficiency. In this study, a wireless sensor node was developed to automatically measure the volume of the product stored in the created mock-up storage bin and a 3D surface reconstruction for visualization. The sensor node utilized a single-broad computer for its computing and wireless functionality. The sensing device comprised LiDAR sensor and a servo motor for data acquisition. The system used an open-source ROS framework to simplify the software along with its data processing pipline and hardware interface integration. The single- board and the end user devices were connected to the same network and used Remote Desktop Protocol (RDP) for remote functionality. Results from three different testing setups revealed an average error of 1.309% between the actual and predicted volume of the flour materials within the mock-up storage bin. This deviation from the actual content volume implies that the developed system offered an alternative method for efficient volume measuring of the storage bin through remote data collection and 3D visualization. © 2023 IEEE.

Our solution is a wireless technology that allows for real-time monitoring of the health of a large number of patients. In health care facilities, patient data such as pulse rate, blood pressure, temperature, and breathing must be monitored on a regular basis. The proposed system monitors the patient's heart rate, temperature, and respiratory rate. To determine heart rate, for example, a heartbeat sensor is used. A transmitting module is installed, which employs a NODE MCU coupled with WIFI to broadcast the encoded serial data indefinitely. In the doctor's cabin, a receiver device is installed that continuously receives and decodes data and displays it on a user interface on a PC or laptop. As a result, the doctor can keep an eye on and monitor a large number of patients at the same time. In addition, the system continuously analyses the data of the patient(s) and transmits an ALERT message to the doctor's mobile phone if any suspected abnormalities are detected. If the doctor is not in his chamber, the system's GSM module sends a message to all of the doctors in the unit, include ng the patient's room number. © 2022 IEEE.

Supplemental Human-Machine interface for Haptic Shared control to Convey sensor Reliability Information to an Operator of Underwater Vehicles

IEEE Transactions on Haptics 2025年 PP卷 PP页

In haptic shared control (HSC) for teleoperation, the human operator and autonomous system share control via torque on the input device. When a discrepancy exists between the human's maneuvering intent and the autonomous maneuver presentation, the human can apply additional force to the device to achieve the desired maneuvering. The required force level is generally predetermined during design and closely relates to the human workload. This study investigated scenarios where discrepancies between human and machine control occur frequently owing to unreliable sensor information. We propose a method to allow the operator to adjust the machine's assist level, facilitating smoother control transitions and proving useful when machine suggestions are unreliable. Conventional HSC systems generally lack sufficient information for operators to make informed decisions regarding adjusting assist levels, leading to delayed decisions and increased workloads. To address this, our research objective is to communicate sensor reliability to humans, thereby facilitating deciding the machine's assist level. We focused on the HSC of a remotely operated underwater vehicle (ROV) where the sensor system is prone to unreliable. Maneuvering experiments with an ROV simulation involving sixteen participants demonstrated the proposed method effectively communicates sensor reliability to operators and reduces mental demand compared to conventional methods. © 2025 IEEE.

Sensing is essential in human cooperative robots to realize safe and powerful operations against contact with the surrounding environment. Contact sensing has been studied for manipulators to avoid accidents caused by collisions between humans and robots. Conventional research has demonstrated that contact sensing requires many sensors or has a limited measurable range. In the conventional research without sensors, pre-identified system models, such as frictional force and plant parameters, have been used to estimate the contact force. However, a high reduction ratio mechanism for achieving powerful operations hinders accurate force estimation. This study proposes a force control system based on only one force/torque sensor on the base frame of the manipulator. The proposal provides an accurate estimation of the contact force and the contact position on a manipulator with a high reduction ratio mechanism. Furthermore, by using the proposal, the contact force and contact position can be detected regardless of the location where the contact force is applied. The validity of the basic principle of the proposal was confirmed in one degree of freedom system through experiments. The results show that the proposal can be controlled with a maximum error of 0.13 N.

Motivated by the recent interest in the modernization of the traditional manufacturing facilities, this work focuses on the development of an automated warehouse where mobile manipulators autonomously navigate in the environment by exploiting additional spatial information gathered by a network of fixed RGB-D sensors. In detail, a navigation approach is proposed wherein both the mobile and fixed nodes composing the system are low-cost devices characterized by limited sensing and computing capabilities. A ROS2-based proof of concept of the outlined scenario is discussed and investigated with special regard to the practical challenges and the possible limitations. The results of some preliminary tests are reported to provide an intuition on the feasibility and potentiality of the designed approach in real-world industrial scenarios.
