Therefore, humans and robot interaction is crucial. However, currently robots are only able to communicate with humans due to physical interaction without any emotion or feeling. In this day and age, robots without emotions are similar to decision makers without passion. So, robots should be provided with the capability to feel the surface of any objects that they are holding. In order to develop robots that can feel or robots that have emotions like humans do, it is important for us to first study human emotions in conjunction with roughness, vibration or even temperature. It is believed that the findings are able to be used as a guidance in robot development. This paper is focusing on the roughness factor. A series of experiment where the kansei survey method was conducted and applied that required a number of participants to touch some surfaces and answer those questions in the survey based on what they feel about having interaction with the surfaces. This paper describes the results of these findings of how humans feel against touching surfaces.

Autism is a brain disorder that affects behaviour, communication and social interaction. The use of intelligent robots to rehabilitate children with autism hosts great untapped potential.Robots offer rehabilitation applications that are accurate, motivating and repetitive.However, validity and access to such intervention are still scarce. This research investigates the potential use of a humanoid robot as an adjunct rehabilitation tool to assist children with autism. The focus is also on developing a single, web-based platform that enables stakeholders in autism rehabilitation to gain access to robotic applications. A robot in human shape has great potential to generalize the skills learnt during human-robot interaction to human-human interaction scenarios. The humanoid robot used in this study is NAO. It has moderate degree of likeness to human.Chi...

It eliminates the distance barrier between a therapist and a child with autism by allowing remote physical interactions between them thus enabling the therapy to be conducted even in a long-distance. In general, the system requires a robot, a child with autism, and a helper which normally is a close kin to be present at one place and a specialized therapist at another. Connected via remote communication technology such as the Internet of Robotics Things (IoRT), a remote therapist is able to monitor the therapy session through robot vision or its sensors and if necessary, provide physical feedbacks through robotic features such as voice or body movements. One of the system’s important aspects is the therapist’s interface controlling the robot. The interface must be user-friendly to non-programmer user yet having enough technica...

The technique consists of 24-items of behavioral assessment which was referenced to the Gilliam Autism Rating Scale-Second Edition (GARS-2). GARS-2 is a screening instrument used to identify and diagnose autism. Preliminary results from a pilot study show that this method had allowed qualitative observation to be carried out to compare the behavior of autistic children with and without the presence of a robot. The feasibility of this technique will be further justified through future wide-spread studies involving a larger number of children spanning across the whole spectrum of autism.

Recent studies have covered the role of robots in clinical and experimental setting but not much on integrating them in educational setting. Our previous work had shown that interaction with a robot poses no adverse effects and that the robot's specific interaction scenarios were associated with less autistic behavior. Extending this impact on school-going children, interactions that are in-tune with special education lessons are needed. This study aims to propose the integration of a robot into current learning environment for children with special needs, specifically autism. Six interaction scenarios had been designed based on the existing syllabus to teach communication skills, using the Applied Behavior Analysis (ABA) technique as the framework. Development of the robotic experience for learning also covers the required set-up involving participation from teachers. The actual research conduct involving school children, teachers and robot shall take place in the next phase.

Composite manufacturing especially requires skilled workers that can complete manual task primarily hand lay-up process in conjunction with composite fabrication methods. Lay-up process is one of the methods in fabricating composite. Mostly, parts of products using composite are enormous; such aircraft body, pools and ship body. This study aims to segregate potential respondents for ergonomics experimental specifically focusing on hand lay-up workers in a composite manufacturing facility. The study uses survey for 28 participants to identify the workers experience on the body discomfort while doing lay-up process activity. Out of sixteen activities in the lay-up process, results show that nine activities are suitable for postural analysis. However, for the preliminary study, only three selected postures which are the most frequent are analyzed. Rapid Upper Limb Analysis (RULA) in Computer-Aided Three-Dimensional Interactive Application (CATIA) V521 software shows RULA score that is above than 5. Hence, the study recommended that the experimentation stage will cover on body parts in upper and lower back of workers. Thus, the respondents for the next step of the research is determined based on their (Body Mass Index) BMI and experience on body discomforts that were obtained from the surveys.

This study is the first one in Malaysia to use PARO; an animal robot as adjunct therapy for a patient with post-stroke depression. Earlier studies show that PARO helps to increase mood, make people happy and encourages human-to-human interaction. The aim of this study is to introduce PARO as a short-term companion to help patient manage depression during rehabilitation period at a multidisciplinary center. Patient was exposed to PARO for 10 min every day for 3 consecutive days. Results show that PARO helped the patient to manage her psychological distress. Her mood improved and she expressed more smiles when holding PARO. This study suggests that PARO effectively uplifts mood and helps patient to be calm. Further research is warranted on the use of PARO for more patients affected with depression.

This solution aims to overcome the distance barrier between autism patients and their therapist to serve as a practical telerehabilitation system. Meanwhile, the Internet of Robotics Things (IoRT) has been identified as the suitable instrument for connectivity of multiple robotic devices in development of physical telerehabilitation system; capable of providing machine-to-machine (M2M) communication and intelligent data processing in telerehabilitation environment. In related study, NAO robot is employed as the "things" to facilitate remote communication and physical interaction between autism patient and therapist thru IoRT network server. However, the technical issue on two-ways communication between this humanoid robot and IoRT network server has remains as the fundamental problem that prevents robot actuators and sensors to be remotely control and manipulate by therapist. Hence, viable data transfer between them cannot be tested. Therefore, a data linking testing between NAO Robot and IoRT network servers such as Microsoft Azure and ThingSpeak is conducted. The proposed data linking concept consists of data communication through NAO Operating System (OS) NAOqi APIs, Python SDKs, and IoRT network architectures. It enables two-ways communication between NAO robot and IoRT networks. The result shows that a set of data sent from NAO robot through Python SDK can be visualized in graph form at ThingSpeak website and vice versa. The result also supported by the back and forth data transfer between NAO robot dummy and

It is essential to engage the students by creating new, affordable robotics at a fraction of the cost. This study presents the design and simulation of a six-axis robot manipulator specifically made for education and training. The robot was developed based on Chriss-Annin's configuration. The robot arm was printed using Fused Deposition Modelling technique using the acrylonitrile butadiene styrene filament. Before it was constructed, the arm parameters were assessed using Scilab as the tool and the traditional and fundamental methods: the Denevit-Hartenberg representation, the forward kinematics, the inverse kinematics, and the trajectory planning. The outcomes showed that the arm was working well on positioning and path planning. Therefore, the complete assembly of the robot should be able to assume a role in education and training.
