Tuong Phuoc Tho,Nguyen Truong Thinh 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

Sorting is one of the important tasks in production line. Using Robot to increase productivity in automatic sorting system interests a large of researchers. In this paper, we recommend a sorting system based on Robot that can identify the position and properties of objects. The sorting system uses the camera placed on the top of the mechanical conveyor belt. With the images captured by the camera, the software will perform the algorithms to identify the location and characteristics of the object (ei. tomatoes), the data of objects is used by pick and place process that synchronize with controller of robot. The sorting process comprising the steps of: detecting the object, determine the object properties (ei. color, size, shape, ...), locate the object, calculate the actual gripping position, the results of the sorting process will be stored and converted into signals to communicate with the control system of robot to perform the sorting tasks. The algorithms will be experimented on Delta robot 3 D.O.F, results will be analyzed and evaluated to calculate the workspace of Robots, so that the productivity and energy efficiency is appropriate.

This paper describes a customized self-feeding system designed to increase the independence of a elder person or Parkinson patient who is unable to use his/her arm for self-feeding. Besides, the procedures of design and development of the system are also carried out, and other its tasks control manipulator to feed the food to patients based on nutrients management for patients. This system can help patients self-control his meal replacement for the care of a family member or care worker thereby saving a lot of time and effort of caregivers, and, nutritional management software of each meal will allow caregivers understand nutritional information of the patients in the diet which can not change to improve the quality of meals for patients. The self-feeding system is experienced and evaluated with several cases in nursing home to give suitable design. The experimental results show that this self-feeding system provides a viable alternative to assisting independence in self-feeding as measured by ingesting time and nutrition intake. The self-feeding system is operated autonomous by itself and sent food"s data and relative information to monitoring computer based on Internet. Besides, the tool of management can analyze the data according to the nutritional standards, and controller control movements of manipulator and automation tray based on health situation and needs of patients.

The paper aims to describe the implementation of racing game named “Arena of Speed” based a Virtual Reality (VR) utilizing a Cable Suspended Parallel Robot (CSPR), a VR headset, and a hand controller. The game “Arena of Speed” is utilized as a special kind of graphical user interface, displaying a computer-generated immersive which can be accessed utilizing hand controller. CSPR can freely manipulate objects in a large workspace with up to 6 degrees of freedom using 8 cables, which activates the proprioceptive sensation of and provides the user with a realistic and exhilarating racing experience. The method of synchronizing the movement of the virtual car with the CSPR is proposed, which includes analyzing and sending data between devices as well as calculating and operating the robot based on game data. The biggest hurdle in replicating the racing experience in real time is that the entire system must work well together and meet the specified deadline. The results of the experiments indicate that the system can provide players playing Arena of Speed with the realistic sensation of racing on a racetrack; however, the sys-tem occasionally misses its deadline with an acceptably low chance. Besides the entertainment purpose, it may also be ideal for individuals who want to experience driving or racing but do not have the opportunity or condition to do so in real life.

This paper discusses the development of a service robot for translating spoken language text into signed languages and vice versa. The motivation for our study is the improvement of accessibility to public information announcements for deaf and less hearing people. The robot can translate Vietnamese sign language into speech and recognize Vietnamese/English speech to suitable gesture/sign language. The paper describes the use of service robot in a sign language machine translation system. Several sign language visualization methods were evaluated on the robot. In order to perform this study a machine translation service robot that uses display screen on robot as service-delivery device was developed as well as a 3D avatar. It was concluded that service robot are suitable service-delivery platforms for sign language machine translation systems.

Novel highly active visible-light photocatalysts in the form of zinc bismuth oxide (ZnBi2O4) and graphite hybrid composites were prepared by coupling via a co-precipitation method followed by calcination at 450 oC. The asprepared ZnBi2O4-graphite hybrid composites were tested for the degradation of rhodamine B (RhB) solutions under visible-light irradiation. The existence of strong electronic coupling between the two components within the ZnBi2O4- graphite heterostructure suppressed the photogenerated recombination of electrons and holes to a remarkable extent. The prepared composite exhibited excellent photocatalytic activity, leading to more than 93% of RhB degradation at an initial concentration of 50mg·L1 with 1.0 g catalyst per liter in 150min. The excellent visible-light photocatalytic mineralization of ZnBi2O4-1.0graphite in comparison with pristine ZnBi2O4 could be attributed to synergetic effects, charge transfer between ZnBi2O4 and graphite, and the separation efficiency of the photogenerated electrons and holes. The photo-induced h+ and the superoxide anion were the major active species responsible for the photodegradation process. The results demonstrate the feasibility of ZnBi2O4-1.0graphite as a potential heterogeneous photocatalyst for environmental remediation.

The traffic conditions in Viet Nam are very complex, there is an increasing demand for autonomous system can control the drivers on street obeying the traffic regulations. From this idea, a human-like robot intending for controlling and monitoring the traffic system was designed and developed. In this paper, a general study on concepts of a robot being used in monitoring and controlling the traffic is presented. The robot totally has 12 degree of freedom (d.o.f), five for an arm and one for actuating the neck and one for a movement of the base. The moving mechanism of traffic-control robot has 12 servomotors. It is equipped with a radio camera and controllers, which allow operation from a remote location. First, a sensing system composed of cameras in the street is developed. By combining the sensing signals and the internal state of the robot, the movements of robot are controlled respective to traffic flow like as real police in real-time. Secondly, a planning algorithm for the robot to performs the command movements like a police. Based on the information from cameras, the robot provides the exact movements of 2 arms and body suitably. Finally, experimental evaluation of the performance of traffic-control robot showed it to be similar to that of traffic police managing and controlling the traffic in real time. The robot has characteristic features of kinematical design and is capable of moving two arms and body performing the complex movements on controlling the traffic like a real traffic police.
