Human-robot collaborative decision method of hexapod robot based on prior knowledge and negotiation strategy

Against the unstructured terrain environment, human drivers often rely on remote operating patterns to accomplish tasks with robots. With the gradual improvement in robot intelligence, a key problem that urgently requires attention is how to bridge cognitive and perceptual differences between human and robot in collaborative decision-making processes. Particularly effective resolution of differences in decision outcomes is crucial. Therefore, this paper utilizes the decision logic process and prior knowledge model of human drivers to form a robot's decision framework, narrowing the cognitive differences between human and robot. Besides, embedding the human-robot-environment features that affect the decision-making process as prior knowledge into the robot's decision-making system can effectively reduce perceptual gaps. Under the same decision framework, a negotiation strategy is proposed for forming a unified decision outcome between human and robot by finding an optimal concession rate. This study utilizes a hexapod robot simulated driving platform to gather experimental data and develop prior knowledge for robots. It also leverages virtual reality equipment and visual augmentation technologies to establish a remote human-robot collaborative decision-making experimental system. The experimental results conducted in complex obstacle terrain demonstrate the effectiveness of adopting the negotiation strategy for human-robot collaborative decision-making. Compared with the individual human or robot decision, the human-robot collaborative decision method significantly enhances robot stability, reduces energy consumption, and minimizes collisions.

Remote Laboratory as an Educational Tool in Robotics Experimental Course

A remote lab is a technology that allows participants to efficiently conduct experimental teaching where users can connect to lab equipment from anywhere without being in a specific physical location. The COVID-19 pandemic affects all areas of human activity. ​As a result, students did not receive face-to-face instruction, and access to the laboratory was limited or practically impossible, and access to laboratory facilities has been limited or nearly impossible. Especially in engineering education, students’ practical abilities cannot be developed comprehensively. In this paper, this paper built an online remote robotics experiment system using digital twin (DT) technology and IoT technology and adopted ADDIE (Analysis, Design, Development, Implementation, and Evaluation) teaching method. With these measures, students can design and debug robot programs at home, just like in the laboratory. This study sent questionnaires to 64 students, and 58 were returned. The results show that more than 80% of students believe that the remote labs for industrial robotics courses have improved the efficiency and quality of students' skills training as opposed to virtual simulation and watching videos on the computer.

Effectiveness of Remote Experimental System for Active Learning in Robust Control

Development of a Shipboard Remote Control and Telemetry Experimental System for Large-Scale Model's Motions and Loads Measurement in Realistic Sea Waves.

Wave-induced motion and load responses are important criteria for ship performance evaluation. Physical experiments have long been an indispensable tool in the predictions of ship’s navigation state, speed, motions, accelerations, sectional loads and wave impact pressure. Currently, majority of the experiments are conducted in laboratory tank environment, where the wave environments are different from the realistic sea waves. In this paper, a laboratory tank testing system for ship motions and loads measurement is reviewed and reported first. Then, a novel large-scale model measurement technique is developed based on the laboratory testing foundations to obtain accurate motion and load responses of ships in realistic sea conditions. For this purpose, a suite of advanced remote control and telemetry experimental system was developed in-house to allow for the implementation of large-scale model seakeeping measurement at sea. The experimental system includes a series of technique sensors, e.g., the Global Position System/Inertial Navigation System (GPS/INS) module, course top, optical fiber sensors, strain gauges, pressure sensors and accelerometers. The developed measurement system was tested by field experiments in coastal seas, which indicates that the proposed large-scale model testing scheme is capable and feasible. Meaningful data including ocean environment parameters, ship navigation state, motions and loads were obtained through the sea trial campaign.

Photovoltaic engineering e-learning applications developed for remote laboratory experimentation systems

In this paper, a functional remote experimentation system tested for long-term use stability and under real weather conditions is presented. The proposed system offers the ability to students and anyone interested to remotely conduct experiments with a real PV module from anywhere on the planet, as long as an Internet connection is available. This innovative system is based on a 55Wp photovoltaic panel installed facing south on the roof of a lab, which is installed on a motorized mount allowing it to alter its tilt angle from 0° to 90°. A camera offers continuous live video streaming of the test site. In order to demonstrate a portion of the aforementioned system’s potential, a set of five proposed educational experiments and exercises that may be performed through the Internet is being comprehensively demonstrated in this paper. Each test creates an I–V and a P–I chart, as well as a TXT file with the test data, which is automatically stored for future use. The procedure only takes a few seconds to complete and the extracted data can then be studied and analyzed in due time, allowing the student to contemplate on the results and put theoretical knowledge into practice. Remote access to a renewable energy lab opens new ways to the education of photovoltaics by offering the students a feeling of direct experience with actual PV equipment and is a process exceptionally useful for part-time learners, distance learners, as well as students with disabilities.

An Assessment of Remote Laboratory Experiments in Radio Communication

Today's electrical and computer engineering graduates need marketable skills to work with electronic devices. Hands-on experiments prepare students to deal with real-world problems and help them to comprehend theoretical concepts and relate these to practical tasks. However, shortage of equipment, high costs, and a lack of human resources for laboratory maintenance and assistance decrease the implementation capacity of hands-on training laboratories. At the same time, the Internet has become a common networking medium and is increasingly used to enhance education. In addition, at many sites, existing experimental systems are typically underutilized. These cost and efficient exploitation constraints can be resolved by the use of remote laboratories accessible through the Internet that can be shared and used at flexible times and from various locations. This paper is a description of a systematic assessment effort of the efficiency of remote laboratories in radio communication. The labs are offered to graduate and undergraduate students, and hands-on and remote experiences are compared. A dedicated remote experimentation system, eComLab, was developed to support the effort.

DOI: 10.2514/1.51380 This paper discusses a method for computing the uncertainty in output metrics of stochastic models due to epistemic uncertainties in the model-input parameters. The method is illustrated by applying it to compute the distribution and confidence interval of the reliability of the Remote Exploration and Experimentation system. This method makes use of Monte Carlo sampling and propagates the epistemic uncertainty in the model parameters through the system reliability model. It acts as a wrapper to already-existing models as well as their solution tools/ techniquesandhasawiderangeofapplicability.Althoughitisasampling-basedmethod,nosimulationiscarriedout whenperforminguncertaintypropagationthroughanalyticmodels,butanalyticoranalytic–numericsolutionofthe underlying stochastic model is performed for each set of input-parameter values, sampled from their distributions. Using the input epistemic uncertainty, in the form of 95% confidence intervals of input parameters of the stochastic model, the two-sided 95% confidence interval of reliability of the Remote Exploration and Experimentation system at a time t 5 years is computed to be (0.949485, 0.981994).
