The emergence of urban search and rescue robotics (USAR) as a field of research is largely attributed to the failure of robots in the field thus far. Existing platforms are unable to fulfill the task of finding survivors because they are expensive, specialized, and require a very long lead time to construct and use. Further, they cannot be localized once a survivor is found. This project seeks to address the issues by developing an untethered unmanned ground vehicle with a multitude of sensors to map its path in 3D, coupled with an intuitive graphical user interface for facilitating two-way communication with the onboard Raspberry Pi micro-computer. In the current prototype, wireless communication is achieved through the Transmission Control Protocol (TCP) over a Wi-Fi connection. Dead reckoning has been used as the technique to process proprioceptive sensor data, meaning the system is not reliant on external support to produce the 3D terrain model. The developed graphical user interface allows easy and intuitive visualization of the terrain model and allows users to mark the model for rescue purpose. The developed prototype has successfully demonstrated its ease of construction, intuitive user interface and capability of automatic terrain mapping.

The emergence of trends such as the Industrial Internet of Things (IIOT), Industry 4.0 and Process analytical technology has heightened the demand for real-time, in-line and affordable sensors. The mass flow rate of bulk solids is a parameter that is invaluable to process understanding in many applications. Despite this the availability of affordable sensors is limited. This paper will investigate some novel methods sensing arrangements utilising cost-effective components including optical and acoustic sensors techniques with a comparison of these methods against a commercial sensor for their evaluation. Experimental results demonstrate that reliable monitoring of powder flow parameters is achieved and that the system is able to track fluctuations of powder flow in pipes in both freefall and pneumatic conveyance applications.

Unmanned surface vehicle (USV) as a new platform has obvious advantages in the marine environmental monitoring. For the requirement of oil spill detection at the sea area of oil spills occur frequently, such as coastal ports, an USV-based laser fluorosensor was developed in our laboratory. In this paper, the overall scheme of USV-based laser fluorosensor system has been proposed, and it consists of shore-based terminal and laser fluorosensor. The laser fluorosensor system has been designed in detail. The axis of the transmitter and receiver in the system are coincident. A micro-pulse nitrogen laser and an ICCD are used as the excitation source and detector respectively. The laser and ICCD are both working at external trigger mode, and a delay generator outputs two TTL signals with fixed delay time to accomplish the time sequence control of the laser and ICCD camera, hence the range-gated detection of the system. The system performance has been tested both in the laboratory and field. The obtained results suggest that the optimal gate pulse delay and gate width of range-gated detection are 112~113ns and 10ns respectively under the condition of 5 meters detection range. The stability of the system has also been tested by repeated measurements, and the relative standard deviation is determined to be 3.47 %. The feasibility of applying the system to the field detection has also been verified in this work.

The main work of this paper is proposed an indoor underwater target positioning system and an improved positioning algorithm. The principle of the system is based on the underwater acoustic positioning method for marine positioning. In addition, the structure of the system and the positioning algorithm are improved for the indoor underwater fixed target. The system is based on the short-baseline principle, combined with an ultrasonic transducer, three hydrophones, and a water depth meter to compose an improved short-baseline array, which is used to locate the underwater target. And the artificial bee colony algorithm is used to deal with the distance information. Then the nonlinear optimization problem is solved, and the positioning accuracy of the system is improved. In this paper, the hardware structure, the positioning principle and the positioning algorithm are discussed. The experimental results show that the underwater target positioning system has the advantages of high precision and high stability, and the performance of the algorithm is obviously better than that of other algorithms.

It is a critical task to teleoperate a robot in a partially known or unstructured environment without any assistance. In this paper, local implicit surface based virtual fixtures are generated real time in a point cloud augmented virtual environment for operation guidance. The point-set implicit local surface method is modified to accomplish local forbidden region virtual fixtures. The robot-centered potential force field model is applied for the guidance virtual fixture generation. The resultant force generated from both forbidden region virtual fixtures and guidance virtual fixtures are fed back in real time to the human operator through a haptic device. With assistance from the guidance force, human operators can implement obstacle avoidance tasks efficiently. The experiment results show that the proposed method is effective for robot teleoperation.

When a part of the scattering light from the target is entering to the laser cavity, the terminal voltage of semiconductor laser diode slightly fluctuates. This voltage fluctuation has the information related to a distance to the target. However, the terminal voltage fluctuation has many noises. Discrimination of distance signal with many noises is almost impossible. Therefore, a statistical signal processing which utilizes the all information in terminal voltage fluctuation is newly proposed. A system is constructed using Field-Programmable Gate Array (FPGA). This system can measure the distance of 21cm to 45cm with the average error of about 2 %.

Finger recovery is much harder than other parts on the upper limbs, because finger recovery movement has several key problems need to overcome, including high precision of movement, high control resolution requirements, variable data with different person, as well as the fuzzy signal during the movement. In order to overcome the difficulties, a new scheme of finger recovery is presented in the paper based on symmetric rehabilitation. In the paralyzed hand side, a mechanical exoskeleton hand is designed and simulated to provide skeletal traction, while in the regular hand side, the curve magnitude of every joint during movement is detected. Then the hand motion is analyzed and recognized using Multi-class SVM. Many candidates were chosen to perform the experiment, and the data produced by the candidates were divided the training parts and recognition parts. Experiments shows that the Multi-class SVM is effective and practical for classification and recognition, and could be helpful in the finger recovery process.

Kinesthetic information is beneficial in detecting, recognizing, and interpreting haptic objects in virtual space. Unfortunately, kinesthetic feedback requires linkage-based high-powered multi-dimensional manipulators, such as exoskeletons or robotic arms, which are currently not possible to integrate with mobile devices. To overcome this challenge, we describe a novel system that is able to apply linkage-free directional forces to a stylus tip, in order to control user input behavior and provide haptic information. Elaborating on the theoretical approach introduced by Reznik and Canny in their `Universal Plannar Manipulator', this paper illustrates the development of the novel “Stick-slip” Kinesthetic Display Surface (SKDS) prototype. The SKDS prototype is an evolution of various design efforts, highlighting the efficiency, accuracy, and reliability of the system. We demonstrate how it is possible to generate directional forces on an interactive display in order to move a linkage-free stylus over a touchscreen in a fully controlled and efficient manner.

This paper presents a novel methodology of calculating an object's frequency of vibration autonomously using a camera and mechanism of optical strobing. The camera used has a frame rate of 30 fps and therefore, in the conventional fashion, it is unable to capture meaningful information about any vibration frequency higher than that. Therefore, we utilize the strobing concept with an illumination frequency higher than camera frame rate and modulo (of division) between object's frequency and strobing frequency is captured in video. Motion in the video is tracked using robust optical flow technique. Finally, frequency is calculated from the frequency plot and the illumination frequency of the strobe. Experimental results show that our method is effective in various real scenarios. The method is noninvasive, computationally less expensive and more scalable compared to the existing systems.
