This project is based on basic vacuum cleaning and robot movement. Those concerned with the design of an autonomoussweeperrobot for a badmintoncourt by using Arduino mega as its brain. It constitutes a smooth, less noisy and user friendly . This idea have been developed an autonomoussweeperrobot for badmintoncourt which is designed to clean a badmintoncourt by using a basic principal of vacuum, the Arduino system as an operating system, a line following concept and basic linear motion as an arm for cleaning purposes . Basically, this autonomoussweeperrobot moving principle based on the line guided at badmintoncourt. This project also used a motor driver to drive a motor vacuum and arm robot. By using Arduino microprocessor works as a brain to control all mobilization and process of the robot. DC motor is used to propel the robot vacuum and the vacuum. However, DC motor spins too fast and has little torque to drive the loads. Thus, gear reduction is required to slow down the rotational speed and increase the torque of the motors. The robot senses the obstacles through the infrared sensor. These sensors are installed at the arm of the robot.
This project are highlight a product with smooth movement and easy to use compared to other products has been reviewed. The goal of this study is to use the component, mechanism or other than products that has been produced before. An autonomoussweeperrobot, a vacuum cleaner-base product is used to clean badminton court’s floor from dust and other dirts, besides, it also polishes the floor to make it clean, smoth surface and shiny. In general, this Vacuum robot is commonly used in the vacuum chambers for handling work pieces such as semiconductor wafers, and other types of work. The vacuum robot motions require high-accuracy and high-speed without concerning the process.
Building a sport robot that can defeat human players in sport activities is the aim of many researchers and engineers in robotic related fields. This paper presents a design of a mobile badmintonrobot that can serve a shuttlecock as a human player in a standard badmintoncourt. A transporting shuttlecock system was designed to preload six shuttlecocks. A serving mechanism was designed to swing a standard badminton racquet to hit a dropping shuttlecock timely. The challenges and the proposed solutions that involved during the development of the shuttlecock serving system and serving mechanism are discussed. Findings indicate that the proposed design is able to preload and serve six shuttlecocks continuously with a success serving rate of 89% in a standard badmintoncourt when the time between swinging the racquet and dropping a shuttlecock was optimized.
This paper has reported experiments incorporating a simpli- fied form of synaptogenesis as the basis of a stable long-term memory mechanism in the A RBIB mobile robot. It has also examined an idea for a medium-term memory, based upon the work of Grey Walter (1951), which in turn is fed from a circuit derived from Wang and Arbib’s (1992) model of the medial pallium. This gives the robot the beginnings of an ability to ignore neutral stimuli in its environment, while also attempting to overcome the problem of conditioning with stimuli which have a large inter-stimulus interval. Thus, A RBIB ’s competence is evolving as its nervous system ex- pands. This will continue as more advanced robot platforms utilising colour vision and manipulator capabilities are em- ployed, allowing greater interaction with the world and sus- taining growth of the nervous system.
The security of home, laboratory, office, factory and building is important to human life. We develop security system that contains a fire protection robot using sensor. The security system can detect abnormal and dangerous situation and notify us. First, we design a fire protection robot with extinguisher for the intelligent building. Besides, Human had difficulties to detect the small burnt cause by electrical appliances. The late time user takes to extinguish the fire. User may take a late time to extinguish fire like finding the water source to extinguish fire when want to extinguish the fire. The fire difficulties to detect the small burnt area and location that is hard to be reach by the user. Sometimes tough fire extinguished for example spaces are hard to see. Besides is cost the loss suffered in the event of fire slow to act.
Abstract: In recent years, robotics in agriculture sector with its implementation based on precision agriculture concept is the newly emerging technology. The main reason behind automation of farming process are saving the time and energy required for performing repetitive farming tasks and increasing the productivity of yield by treating every crop individually using precision farming concept. Designing of such robots is modeled based on particular approach and certain considerations of agriculture environment in which it is going to work.A robot capable of performing operations like automatic ploughing, seed dispensing and pesticide spraying is developed. It also provides manual control when required and keeps tabs on the humidity with the help of humidity sensors .The main component here is the ARM 7 microcontroller LPC2148 that supervises the entire process. Initially the robot tills the entire field and proceeds to ploughing, simultaneously dispensing seeds side by side. The device used for navigation is an ultrasonic sensor which continuously sends data to the microcontroller. On the field the robot operates on automated mode, but outside the field is strictly operated in manual mode. For manual control the robot uses the zigbee or wifi modules as control device and helps in the navigation of the robot outside the field. The field is fitted with humidity sensors placed at various spots that continuously monitor the environment for humidity levels. It checks these levels with the set point for humidity and alerts the farmer.
It has been successfully proven through this proposed theory and concepts for a landmine exploring platform works perfectly. It will able to clear the path with 1m width at one go. The greatest advantage that this robot offers is the safety for the soldiers on war field. It will send the location of buried mine to the operators by using GSM module. This means that if the operator or the soldiers follow the tire tracks, they are perfectly safe since the robot has already rolled over it. Thus, the proposed design for landmine detection and marking module had opened up a new area for the researchers to explore. Saving the lives and limbs of innocent civilians becomes one step closer. In future we can also use the camera for better images of buried mines.
In the world of globalization, different technologists are upgrading a new development based on automation which works very effectively and within a period of time. The rapid growth in the industries forces the labors who are situating in the villages to migrate to the cities. This issue creates the labor problem for the agricultural operations. The wages for the labor is also more. These factors forces the farmers who are interested in agricultural activity to leave their land uncultivated. So it’s a time to automate the sector to overcome this problem. An imaginative idea of our project is to automate the process of sowing crops such as sunflower, groundnut, cotton and vegetables like beans, lady’s finger, pumpkin and pulses like black gram, green gram etc to reduce the human effort and increase the yield. The plantations of seeds are automatically done by using DC motor. The distance between the two seeds are controlled and varied by using Microcontroller. It is also possible to cultivate different kinds of seeds with different distance. Also the project consists of sprinkler, which would be used for reducing the wastage of fertilizers that is done by spraying appropriate amount of fertilizers required for the particular crop. The sprinkler would sprinkle on the senses from wheel movement and the on and off of the sprinkler would be controlled by Microcontroller. The whole process is controlled by Microcontroller.
So in this project, our goal is to address the di ﬀ erent as- pects required in making an autonomousrobot recognize textual messages placed in real-world environments. Our ob- jective is not to develop new Character Recognition algo- rithms. Instead, we want to integrate the appropriate tech- niques to demonstrate that such intelligent capability can be implemented on a mobile robotic platform and under which constraints, using current hardware and software technolo- gies. Our approach processes messages by extracting char- acters one by one, grouping them into strings when nec- essary. Each character is assumed to be made of one seg- ment (all connected pixels): characters made of multiple seg- ments are not considered. Messages are placed perpendic- ular to the floor on flat surfaces, at about the same height of the robot. Our approach integrates techniques for (1) perceiving characters using color segmentation, (2) posi- tioning and capturing an image of su ﬃ cient resolution us- ing behavior-producing modules and proportional-integral- derivative (PID) controllers for the autonomous control of the pan-tilt-zoom (PTZ) camera, (3) exploiting simple heuristics to select image regions that could contain charac- ters, and (4) recognizing characters using a neural network.
V. E XPERIMENTAL R ESULTS OF A UTONOMOUS T RAVELING After the preliminary test, we conducted experiment on the considered pattern shown in Fig.2(d). Fig.5(a) shows the results. The entire patter can be classified into three groups: linear, square, and combination of these two as shown in the figure. Fig.5(a) shows linear, square, and the combined form of driving algorithm under FWS condition. The graph shows the x position of the mobile robot at different driving distances with SV S40 and camera angle D. Fig.(b) shows linear, square, and the combined form of driving algorithm under RWS condition. The graph shows the x position of the mobile robot at different driving distances with SV S40 and camera angle D. Fig.5(c) shows the comparison between FWS and RWS in terms of steering angle at same speed value and camera angle over the entire length. Fig.(d) shows the comparison between FWS and RWS in terms of steering angle at same speed value and camera angle over the entire length in opposite direction of the considered path pattern. Fig. 5(e) shows the comparison between FWS and RWS under same condition. As can be seen there is not much difference except the time delay in case of RWS.
In the context of electromagnetic compatibility, the knowl- edge of the electromagnetic field distribution in a certain plane or volume is often required. This information can be used to verify the efficiency of shielding measures or to cal- ibrate field simulators, for example. During such measure- ment campaigns, usually a large amount of data is collected for a lot of positions in the test area. Taking these measure- ments manually can be very time-consuming. To speed-up the process, the field probe can be placed at the designated positions by a robot. There are several specialized auto- mated measurement systems, designed for special applica- tions (e.g. (Haake, 2010)). Most of these systems cover a given maximum volume depending on its skeleton size. The probe manipulation is usually done with rectangularly arranged wooden or plastic arms.
The article deals with the fuzzy velocity control of an autonomous wheeled mobile robots motion in an unstructured environment with obstacles [4-9]. This article presents how to control of motion and velocity of wheeled mobile robots in an unstructured environment that contains obstacles with using ultrasonic sensors and a stereovision system.
Normally cleaning of wide windows on tall and multi-story buildings is quite tedious and very dangerous procedure. It can be done outside either using hoisting machines with manual cleaning or very rare by sophisticated, complex, large, heavy and very expensive automatic cleaning machines operated manually from the ground floor. These large machines, besides, have to carry a bunch of umbilical pneumatic and electrical cables while cleaning the windows. As a result, they are not popular in housekeeping operations. Therefore, the use of autonomous window

There are two problems encountered by the players is difficult to conduct training alone, waste of energy to move around the tennis court for collecting balls. The problem appears to when a player would like to carry out the training and the person has no partner or coach to serve the balls. The project idea is generated to design and develop a robot to replace the training assistant or second player with robot when time to warming up.
To overcome the beforementioned difficulties there is the need to increase the ratio between scientific results and the ef- fort in terms of manpower and money spent. One way could be to make achievements better visible to the scientific world outside of robot soccer. E.g. most websites of robots soccer teams show nice pictures and videos about their participation but only a few websites describe the individual research goals of the teams and the scientific achievements. Neither the sci- entific world nor the general public have the chance to get some ideas of what is the level of development in each league. Even for robot soccer participants the further development in other leagues remain vague. Furthermore, the results from the technical challenges are not available online, even some tour- nament results are missing. Here, a better presentation would already help a lot. It would also be a good idea to present the best scientific improvements of the present year in a special issue of a journal that has a better visibility than the RoboCup symposium. Moreover, it would foster scientific work of the RoboCup teams. For comparison, the journal of field robotics has reserved three issues for the teams which reached the fi- nals of the DARPA urban challenge.
Mobile robots are mechanical devices capable of moving in an environment with a certain degree of autonomy and posses nonholonomic properties caused by nonintegrable differential constraints while Autonomous robots are robots which can perform desired tasks in unstructured environments without continuous human guidance. Many kinds of robots have some degree of autonomy. Different robots can be autonomous in different ways. A high degree of autonomy is particularly desirable in fields such as space exploration, cleaning floors, mowing lawns, and waste water treatment.
configurable chassis may as a result not be able to carry a particularly large payload due to the chassis of the robot having less structural integrity. This means that when determining the final design of a mobile robot platform, some compromises may need to be made to ensure a platform is as flexible as possible without unduly impairing the other aspects of the robot platform. One factor which has an overbearing influence on the ability to include other factors into a mobile robot design is low cost. By limiting the cost of a mobile robot design it may not be possible to satisfy all of the factors to create a flexible robot platform. For example an entirely re-configurable chassis may cost considerably more than one that is only partially configurable. As a result compromises may need to be made to designs in order to create a balance amongst all the flexibility factors.
