Modeling Deformation of Spur Gear

In The work considers 11 types of gears, features of their design and application. Analysis of gears designs is carried out, since shape of teeth directly affects process of teeth gearing, and this, in turn, affects load, which causes deformation of elements. 3D model of spur gear was created in ANSYS system. The work was limited by analyzing problem from point of view of gear wheels’ deformation, which were made of 40L carbon steel and carbon composite material. As a result, finite element modeling and analysis of gears using ANSYS system was carried out.

Anti-Theft Box: Arduino Safety Box with IoT Notifications

Theft cases often go unnoticed and are everywhere we are. It can happen in public, at school, at work or even in your own home. Things like this often happen to teens and older adults. Some of them do not have a safe place to store their valuables because of their carelessness. This is because they do not take this seriously. On the other hand, they already have their own safety box which is a great example of keeping items from being stolen or robbed. With the Internet of Things (IoT), this safety box can be improved by adding features that make it even safer to receive notifications on a mobile phone when the safety box is opened. With these improvements, property owners will become more aware of their goods because not everyone around us can be trusted. The use of these notifications is an update that will be created to improve the security of your goods. The methodology used to carry out this project is called Prototyping Method. In this way, prototype can be said to be both a design and an example of an existing system, but not yet fully functional. Prototypes will outline how a system works, and most prototype systems are not yet the perfect system to run.

Modern Walking Robots: A Brief Overview

In this review, we would like to present some of the most interesting modern designs of walking robots: bipedal, quadropedal, hexopedal, and octopods. Their advantages and disadvantages are highlighted. It has been determined that structures with eight or more limbs are ineffective due to high level of electricity consumption. The use of more than six number of legs does not give noticeable advantages in profile cross-country ability or maneuverability, however, it allows to reduce the forces and moments of inertia forces due to decrease in mode coefficient (ratio of time spent by propulsor in support to time of entire step), and, consequently, smoother leg movements in swing phase.

IoT-Based Solar Energy

Problems with a shortage of electricity often occur, especially in a rural area, which makes it difficult to do daily work and makes it difficult to communicate with outsiders. Problems with a shortage of electricity can affect the daily activities of residents, especially in rural areas, and can pose risks in the event of emergencies such as illnesses that require mechanical treatment. If this problem persists it could be detrimental to the population who do not have electricity. Electricity is very important as it can make it easier for people to do the work and for the people in the interior to get information. Problems with a shortage of electricity can affect communication networks such as the internet, radio waves, mobile phone lines and so on. In the current state of technology development, the creation of technologies that can solve this problem must be done and referred to as Solar Energy. It is an IoT research that absorbs energy from the sun to produce electricity in every home. The movement of this research can be controlled manually by using a mobile phone connected to the internet and also controlled automatically by the direction of sunlight. With this, updates from users are a must. This meets the user's need for a device that can be used continuously.

Smart Smoke Detector

In the past few decades many studies and researches have taken place in order to improve security systems and to increase their level of protection in different fields. One of the major problems that security must deal with is the fire outbreak that can happen in everywhere including houses, schools, factories and many other places, and to avoid that or to minimize the damage caused by fire outbreak an IoT technology is used to control such a kind of risk. IoT is a modern system that consist of sensors and switches connected. In this project we will use temperature sensor known as (Flame sensor) with Arduino device to detect fire outbreak and to measure the amount of heat intensity generated by a fire outbreak or in a specific location in our house, offices and other places. It sometimes takes too much time for the fire station to reach to the fire outbreak location and works on extinguish the fire and so these sensors will work as an early alarm system which will send a notification to our mobile phones if any fire outbreak occurred to let us know the situation clearly and before it’s too late, we act to avoid significant damage in case the fire outbreak was observed after a long time from its outbreak.

Smart Door Lock

Internet of Things (IoT) has become a phenomenon in many researchers. A smart digital automated system based on IoT plays major role which helps in reducing human work by applying interaction technology in daily life. This research introduces the IoT Smart Door Lock where smartphone uses Wireless Fidelity (Wi-Fi) to activate the door lock. By using Android software, the smartphone will automatically activate the door lock within a specific range. Data transmission will be done using Wi-Fi technology. So, the user does not have to worry whether the door has been locked or not because user can control it by using their smartphone within a specific range. The user also does not have to worry about losing the door key anymore because there is no device required except user’s smartphone. This project consists of hardware and software development. The main purpose on the design is to prevent the situation where the user is unable to unlock the door when the key is missing also to give a solution for users to monitor door status when they forget the door has been locked or not. This system aims to eliminate the use of keys to access the door, where the daily struggle faced to bring along a bunch of keys anywhere. Besides that, the door locking system must function efficiently. The prototype of this system is successfully done, the procedure and the software and hardware requirement has been compiled in this report.

Intelligent Egg Incubator

This research presents the design and development of a chicken egg incubator. The aim is to design and construct an “Intelligent Egg Incubator” that can hatch chicken eggs automatically. In the design, author used a temperature control system that controls the temperature of the incubator. This system consists of a temperature sensor, heating and cooling elements and a controller. If the temperature of the incubator exceeds a certain value, the cooling unit will operate to reduce the temperature while if the temperature goes below another threshold value, the heating element will start to operate to increase the temperature. Furthermore, author used a motion sensor to detect the movements of the eggs. If there is a movement inside the incubator, the owner of the incubator will get the notification about the conditions of the eggs

A Design Remote Control System to Feed Birds Using ESP8266

Keeping lovebirds at home becomes one of hobbies that is fascinating to some people. Keeping them as pets means educate us to be regular people, particularly related to the process of food provision. Innovation on feeding bird is required such as automatic feeding which can be controlled from far areas. It will be very beneficial when the lovebird keepers are not at home. Therefore, this study develops at designing an automatic system for feeding birds completed with remote control. For this reason, the researcher used ESP8266 connected to NODEMCU as the hardware and BLYNK server as the control bridge of internet. The data would then be transmitted from smartphone to esp8266 system to control the feeding process. In the context of feeding process, the researcher used RTC-clock owned by BLYNK server to substitute RTC as the hardware. Automation system of food provision was carried out by synchronizing the data of hours from the users. The research data were used to design feeder bucket which could give food around 7.2 - 52.8 grams and feeder bucket B for accommodating food about 6.2 - 48.3 grams. The results of control and connection via BLYNK server demonstrated that 90% data were connected. In terms of data accuracy, this automatic feeder could be accurately 100% successful in a certain time.

Solar Tracker

Solar Tracker The generation of power from the reduction of fossil fuels is the biggest challenge for the next half century. The idea of converting solar energy into electrical energy using photovoltaic panels holds its place in the front row compared to other renewable sources. But the continuous change in the relative angle of the sun with reference to the earth reduces the watts delivered by solar panel. Conventional solar panel, fixed with a certain angle, limits their area of exposure from the sun due to rotation of the earth. Output of the solar cells depends on the intensity of the sun and the angle of incidence. To solve this problem, an automatic solar cell is needed, where the Solar Tracker will track the motion of the sun across the sky to ensure that the maximum amount of sunlight strikes the panels throughout the day. By using Light Dependent Resistors, it will navigate the solar panel to get the best angle of exposure of light from the sun.
