Currently, artificial intelligence and virtual technology are widely used in motion monitoring. virtual entertainment robots can provide adaptive and personalized fitness services for different user groups, allowing users to experience the exercise process in games. This article studies the virtual entertainment robot based on artificial intelligence image capture system for sports and fitness posture recognition. Firstly, this article explores deep learning methods for motion recognition. By constructing a generative adversarial network to obtain discrimination results, and calculating its anti-loss function. This approach can improve the efficiency of human body movement style conversion through adversarial training. Finally, through the evaluation of movement posture and action recognition, quantitative evaluation results and targeted guidance strategies can be provided to help correct incorrect movements and master correct techniques. Using motion capture systems to identify user movements during exercise not only accurately extracts user fitness movement information, but also makes it easier to use and reduces user costs. The system uses motion evaluation techniques for evaluation to help users correct incorrect fitness habits, prevent exercise losses, and exercise more safely and effectively.

One ofof the benefits that education reaps from virtual Reality (VR) is the ability to visualize, simulate and interact with virtual objects. This ability allows the students to have the trial and error session before actually practicing it on real things. Here comes to the point where the idea of having virtual robot in assisting students learning emerged. Instead of studying the physical robot in class, students can study the virtual robot on computer at home prior to class or even in the class itself. Students can immerse themselves in this digitized world;experience the sense of moving and becoming part of the robot system. This paper presents the methodology for the whole-robot 3D graphics design, integration between the object modeling to VR, and the construction of real-time behavior and interactivity modification to accommodate changes in the virtual environment.

The task of formation maintenance is of great importance in high level applications being executed by multi-robot systems, such as exploration, surveillance and cleaning, among others. This article presents a strategy for formation maintenance in a group of mobile, cooperative, homogenous robots, which work together with a software agent known as "virtual robot". This virtual agent acts as reference for the spatial localization of each robot, and facilitates the navigation tasks of the group. This approach combines the characteristics of other well known formation reference strategies: leader- and unit-center referenced formations. The proccess of validating this strategy was obtained from both simulated and real multirobot systems.

A kinematical analysis method on virtual robot is introduced. Weight calculation is utilized to solve the differences between virtual robots for text-to-visual speech synthesis and traditional joint-typed robots in kinematical analysis method. The method is divided into three major steps: firstly, establish a Denavit-Hartenberg (D-H) parameter table;secondly, establish kinematical equations of these linkage systems;thirdly, choose a proper equation in those kinematical equations which has different intensity levels by the weight. Experiment result shows that the proposed method can apparently reduce the difficulty of kinematical analysis and optimize the control. It is expected to have a strong practicality in virtual robot research.

The robot is a machine and is a re-programmable, multi-functional regulator expected for transport various kinds of material, parts, instruments, or thought contraptions from end to end factor-altered developments for the carrying out of a grouping of tasks. Mechanical technology is portrayed as the discipline or examination of the development basically associated with the arrangement, production, speculation, and utilization of robots. Advanced mechanics are a science utilizing the proceeding with headways of mechanical design, sensor creation, material science, advanced calculations, and producing strategies, while various fields add to the science, the techniques, and the sections, mechanical independence makes the completed outcome. robot makers can fabricate robots with more agreeable parts and mechanical constructions without losing execution, and robots can be utilized likewise in applications with extremely elite prerequisites, just like in smart manufacturing assembly line and machining. This paper presents the proposed and modeling of an industrial robot modeling in virtual platform to describe the end-effector trajectory through forward kinematics mechanism. Trajectory planning referred as path motion planning of end-effector. Now, end-effector is visiting through via points. It is observed from the simulation that the position and velocities are continuous by following C0 continuity when end-effector passes through via points. Uniqueness of this work is that the trajectory produces smooth continuous motion while passing through assigned via points (generated intermediate points through iteration process algorithm). © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper presents the development of a robotic system for the rehabilitation and quality of life improvement of children with cerebral palsy (CP). The system consists of four modules and is based on a virtual humanoid robot that is meant to motivate and encourage children in their rehabilitation programs. The efficiency of the developed system was tested on two children with CP. The effect of using the robot is an increase in the number of exercise repetitions, as well as the time spent on therapy, developing and strengthening the child's musculature. Additionally, the children are able to produce socially acceptable gestures in the context of non-verbal communication for socialization. The main advantages of this system are its flexibility and ease of use. Besides the proposed use in CP rehabilitation, this system can be used in the rehabilitation of people recovering from surgery or injuries. Use of the proposed system significantly decreases the work load of the therapist who would be conducting the repetitive motion, allowing the therapist to see an increased number of patients. In the future, the number of different movements the robot is able to perform will be increased by way of domain-specific modelling and language.

Social skills are the skills that humans use to communicate with each other verbally and non-verbally. The deficit of social skills is a core symptom of children with autism spectrum disorder (ASD). Physical social robots and virtual environments have been popular training tools for children with ASD in recent years. The Jammo-Vrobot environment is a virtual desktop environment that employs a 3D virtual humanoid robot (Jammo Vrobot) to enhance the social skills of children with high-functioning autism (HFA) through a social skills training program guided by a parent or a teacher. The social skill training programme targets three social skills: imitation, emotion recognition and expression, and intransitive gesture. The evaluation process was conducted mostly online with some on-site, including children with HFA (aged 4-12 years). The experimental sessions reveal encouraging results showing that the Jammo-Vrobot environment helps in training and enhancing the target three skills of the participants.

As climate change and biodiversity loss are threatening the natural world's equilibrium and survival, people's concerns about these topics have increased significantly. The work presented in this paper lies at the cross-section between the areas of education, biodiversity and technologies. More specifically, this project builds on research in virtual agents in educational settings to promote young children's engagement with a biodiversity curriculum. In this context, we conducted an observational study with 105 primary school's children with the goal of evaluating the effectiveness of a virtual robotic agent (presented through a multimedia application), in providing an effective and engaging learning experience about local biodiversity to children. Our results suggested that a) older children (8 to 10 years) knowledge about certain animals and plants from their local biodiversity is well matured;b) younger children (6 to 7 years) present more faithful conceptualisations about nature-related scenarios compared to older children and c) both young and older children exhibited a preference for nature-related scenarios when compared to human-made ones. Our findings provide useful information in favour of the usefulness of implementing user-adaptive learning systems, by considering factors like the children's previous level of knowledge. Besides, this personalised and interactive type of system might provide an essential advantage in learning scenarios, compared to "static" systems, in enhancing children's learning outcomes.

The paper describes our preliminary investigation of haptic interaction between the human and virtual iCub robot. With haptic interaction, the user is able to have tactile sensensaiton of the robot environment, and hence to manipulate a robot remotely, for instance, from the user's office to perform some tasks at home, or a patient operation, realized by a surgeon several miles away. In this work, haptic interaction has been implemented using a 3D joystick, Novint Falcon, to connect with a virtual robot created by the Cub Simulator, which works with YARP interface and simulates the real iCub robot developed by Italian scientists. To this end, two approaches based on CHAI3D and MATLAB are introduced and implemented in this paper and furthermore, some ideas to improve the human-robot interaction performance have also been discussed.

In this paper we explore whether the uncanny valley effect, which is found for human-like appearances, can also be found for animal-like virtual characters such as virtual robots and other types of virtual animals. In contrast to studies that investigate human-like appearance, there is much less information about the effects concerning how a virtual character's animal-likeness influences their users' perception. In total, 162 participants evaluated six different virtual panda designs in an online questionnaire. Participants were asked to rate different panda faces in terms of their familiarity, commonality, naturalness, attractiveness, interestingness, and animateness. The results show that a robot animal is perceived as less familiar, common, attractive, and natural. The robot animal is interesting and animate to users, but no big differences with the other images are found. We propose future applications for the human-(animal) robot interaction as tutorial agents in videogames, virtual reality, simulation robot labs using real-time facial animation.
