  • In this paper, we develop a dust detection sensor system capable of identifying types of dust for an improvement of a robot vacuum cleaner. The dust detection sensor system is composed of a set of infra-red sensors: a single transmitter and multiple receivers. Given the fixed amount of light transmitted from the transmitter, the amount of light coming in multiple receiver sensors varies, depending on the type and density of dust that is passing between the transmitter and the receivers. Therefore, the type of dust can be identified by means of observing the change of the amount of light from the receiver sensors. For experiments, we use two types of dust, rice and sesame, and validate the effectiveness of the proposed method.

  • The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which is the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash and has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. In this paper, a Home Mess-Cleanup Robot(HMR), which has a practical function of the automatic mess-cleanup, is developed. It need functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of the self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulation system, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It need to also has the entertainment functions for the good communication between the human and HMR. Therefore, the Home Mess-cleanup Robot with Entertainmental Human Interface is developed in this paper. Finally, the good performance of the designed machine, HMR'4, is confirmed through the results of the mess clean-up and arrangement.

  • This paper is presented for robot vacuum cleaners using BLDC motors. Recently, BLDC motors which require smaller size, lower sound noise and higher efficiency have been placed in high value-added products including robot vacuum cleaners, vehicle cars and other industry applications. The DC motors have higher sound noise, higher height of the size and lower efficiency due to electro-magnetic structure using the brushes and the commutators. The proposed BLDC motors are appropriate for the motors adequate in regards to higher efficiency, longer life cycle time, and smaller height of the size when robot vacuum cleaners go to some lower height of the space like under sleeping beds and because it's power source is batteries. The paper shows the performance of the BLDC motors designed by the Finite Element Analysis(FEA) of the electro-magnetic field. This paper shows the mechanical structure and the prototype of the motor with the impeller. The performance characteristics of the BLDC motors with the hall sensor controller are verified by the experimental results.

  • 전 세계적으로 미세먼지는 심각한 사회문제이다. 우리나라 또한 중국의 미세먼지와 디젤 자동차 급증 등에 의한 오염으로 인하여 호흡 시 들이마시는 공기의 질이 많이 나빠지고 있는 추세이다. 이로 인해 집 안의 환기를 위해 창문을 열거나 외출 후 귀가했을 때 옷에 붙은 미세먼지들에 의하여 집 안에 미세먼지가 쌓이게 됨으로써 건강을 위협할 수 있는 요소가 된다. 이러한 문제점들을 해결하고자 청소뿐만 아니라 공기청정 기능도 수행하게 되는 효율적인 측면을 가진 공기청정 기능을 탑재한 로봇청소기를 개발하였다. 따라서 본 논문에서는 로봇청소기의 초음파 센서와 미세먼지를 사용하여 자동으로 로봇청소기와 공기청정 기능을 탑재한 로봇청소기에 대한 연구 결과에 관해 기술하였다.

  • This paper deals with a 'Designeer' education program that has a specific objective of educating design to undergraduate students in mechanical engineering with the aim of enhancing their ability of collaboration with designers when they are going to work in the field after graduation. The entire curriculum of the Designeer education program is introduced first, the end of which two-semester Capstone Design Courses for senior students is offered to let them practice all the knowledge and skills in a project-based learning environment. Learning specific matters such as sketching & visual thinking, prototyping and user experience design is one thing and practicing those knowledge and skills into a Capstone Design project is another. At this point, design thinking process needs to be in place to give students a foresight of one-year journey and to ensure that they will produce a desirable, feasible and viable product at the end of the year when they define the right problem at the beginning. Their frustrations and discoveries while applying design thinking throughout the year is explained by taking an example of a Robot Vacuum Cleaner design project. Finally, we provide real examples of effective methods to practice divergent and convergent phases.

  • 4차 산업혁명 시대로 들어서면서 인공지능, 로봇산업이 크게 떠오르고 활발해지기 시작했으며 특히 가정용 제품들이 많이 나오고 있다. 최근 들어 미세먼지, 황사 등 공기 중의 미세먼지나 세균 바이러스로 인해 호흡기 질병에 많이 걸리고 이러한 환경문제 때문에 많은 사람들이 집안 공기를 정화 시킬 수 있는 공기청정기를 많이 구매하고 있다. 대부분 집의 일반적인 공기청정기는 한 자리에서 한정된 공간의 공기만 정화 시키고 다른 공간에 필요하면 직접 옮기거나 추가로 구매해야 하는 문제가 있다. 이러한 문제를 해결 하기위해 비교적 가정에 많이 사용하고 있는 로봇청소기에 공기 청정기 기능을 접목시켜 청소를 하면서 생기는 먼지들을 걸러내는 동시에 공기청정기능 까지 접목시켜 로봇청소기가 움직이며 여러 공간을 청소도 하며 공기 청정 기능 까지 하고 로봇청소기가 작동 안 할 때는 공기청정기의 기능만 하여 따로 로봇청소기와 공기청정기를 구매할 필요가 없어 공간절약과 비용감소 효과를 기대할 수 있을 것이다.

  • Traditional vacuum cleaner adoptsa highly rotating centrifugal impeller for generating suction region at lower pressure. The rotational speed is very high at 35,000 to 40,000 rpm and accessory structure such as a circular brush at the base plate of the cleaning devices is equipped for gathering dusts. Highly rotating impeller is effective for low pressure generation but causes noise problems. Recently, the unwanted noise is removed by installation of air-pump, instead of a centrifugal impeller, and the internal flows of the modified system are estimated in numerical and experimental approach, respectively.
