Everything you Need to Know about SLAM




SLAM is short for Simultaneous Localization and Mapping.   For autonomous vehicles that allow you to build a map and then locate your car on it simultaneously, this method is ideal. The algorithms make the vehicle possible so that areas unfamiliar to it can be mapped out. In addition to this, engineers use the map data to perform various tasks such as obstacle avoidance and route planning. To find out more, read on.

Why SLAM Is Relevant

SLAM has been used to do technical analysis for many years. However since the speed of computer processing has increased exponentially and low-cost sensors have been made available, SLAM is used in various fields for a variety of practical applications.

Examples for SLAM

A robot vacuum is an instance of a SLAM. The robot vacuum can move around arbitrarily in the absence of SLAM. As a consequence, the whole room will not be swept. In addition, this strategy will consume much more power and the battery will run out much faster.

SLAM-based robots, on the other hand, can allow the vacuum to work better. This technology actually uses technological knowledge, such as the number of revolutions that come from sensors and cameras for imaging. This is referred to as localization and prevents the computer from moving twice through the same location.

In other fields of use such as parking a car and navigating mobile robots, SLAM is very useful, just to name a few.

How SLAM Works

Generally, for this technology, two types of components are used. The first type is known as the processing of sensor signals, which requires numerous processing types.

This technology involves optimizing the pose graph, which involves processing the back end.

Visual SLAM

Visual SLAM is referred to as vSLAM, too. It makes use of images and cameras from image sensors. This means basic cameras, such as spherical cameras, wide-angle cameras, and fish-eye cameras, just to name a few.

Without investing a lot of money, the best thing about visual SLAM is that it can be applied. Besides, you can use them to detect landmarks since cameras give a lot of information. Combining landmark detection with graph-based optimization is possible.

Monocular SLAM refers to a device in which only one camera is used. Depth, which can be resolved by detecting AR markers and checkerboards, is therefore difficult to define.

This technology involves optimizing the pose graph, which involves processing the back end.

SLAM’s advent

In 1995, at the International Symposium on Robotics Science, SLAM was presented for the first time. At the IEEE Robotics and Automation Conference, a mathematical description was given in 1986. Studies were carried out after the conference in order to find out more about navigation devices and statistical hypotheses.

Experts implemented a system to incorporate one camera after more than a decade to accomplish the same goal instead of using several sensors. As a consequence, these attempts led to the development of SLAM based on vision. In order to get a three-dimensional location, this scheme used cameras.

This was a great accomplishment of that period, without any doubt. We have seen the implementation of these systems in a variety of areas since then.

The SLAM Core, Mapping, and Localization

Now let’s find out more about SLAM systems mapping, localization, and the core. This will help you learn more about this technology and have a better understanding of how effective it has been proved.


Localization will assist you in deciding where you are. Basically, on the basis of visual details, SLAM gives you an estimate of the spot. It is like when for the first time, you come across a mysterious place.

We can get lost because we humans do not have a good sense of safety and distance. With regard to the surrounding area, the best thing about SLAM-based robots is that they can quickly find out the way. It is critical, however, that the map should be highly trained to detect your position.


Mapping refers to a tool that helps to analyze information gathered from a sensor by the robot. Vision-based systems typically make use of cameras as sensitive sensors. Triangulation techniques are implemented to obtain a three-dimensional position after the production of adequate motion parallax in two-dimensional locations.

The beauty of augmented reality is that in a real world, it can help collect data from virtual images. In order to understand the world around it and spot the relative location of cameras, however, augmented reality requires some technologies.

So in a variety of areas, such as position interaction, gui, graphics, display, and tracking, you can see that SLAM plays a very important role.



This was an introduction to slam and its characteristics, long story short. Hopefully, this article will allow you to get a deeper understanding of the method and the areas in which vehicles and other devices are employed for better performance.

Home Improvement Ideas for 2021



Home Automation Systems

With most people in the world spending vastly more time at home than before, change is inevitable. Spending lots of time at home allows people to examine their surroundings and want to make modifications.

2021 is an excellent year to brush up on your passions, and home improvement is no exception. With a little innovation and dedication, you can quickly transform your house into a home. With the rapid advancement and growth of technology, smart homes have become irresistible.

Home improvement ideas have to embrace technology to keep up with the global home automation trend. Here are home improvement ideas you should contemplate.

1. Entertainment

Home entertainment and entertaining visitors will most likely be a spotlight of home improvement ideas for 2021. With entertainment outlets such as pubs, restaurants, and cinemas closed to the public, you could host get-togethers with loved ones in your own home.

1. Home Audio

Enjoy the sounds of a live music festival from the comfort of your home. Music lovers can savor music in their house or their backyard. You will need to contact a professional integrator to install a comprehensive distributed home audio system that includes both indoor and outdoor speakers.

It is worth noting that professional installers usually use in-wall and in-ceiling speakers for distributed audio. This will keep your home aesthetically appealing without disarraying your spaces with wireless speakers.

2. Wi-Fi

Almost every home entertainment system in this century is dependent on coherent, dependable Wi-Fi. If you live in a bigger house or if your internet connection is prone to irritating dead zones, it will greatly impair your streaming experience. The glaring solution is to upgrade your conventional router-based Wi-Fi to a mesh Wi-Fi system.

Since Advanced Network Assist technology is in-built, the mesh network is optimized in the background without the need for user intervention. Besides, with its family controls, mesh Wi-Fi allows you to monitor and manage your children’s Internet activity, which is a classy bonus.

2. Security

Home security has to be the epitome of home improvement ideas for 2021. A smart security system can do more than just alerting you whenever a burglar attempts to enter your home. It connects entry sensors and sirens to devices such as smart door locks, smart thermostats, and smart lighting through your Wi-Fi network.

These are the key features your smart home system can entail.

1. A Home Alarm Security System

Your first step in protecting your home will be to install a smart security system. Have a smart system to protect your entry points and inner levels of your home such as the hallway. Also have at least one smoke detector which can be in the kitchen or hallway. If you reside in an apartment complex, have at least a smoke detector on every level.

2. Smart Lighting

Additionally, lighting will deter intruders. Getting lights that are programmed to turn on and off at odd intervals each day will help to protect your house while you are away. Better yet, you can opt for security lights with surveillance cameras. As a result, anytime someone approaches your home, the camera lens will record a video of the person. This will assist you in either taking precautionary measures or later viewing the footage.

3. Cleaning Devices

We all know that a clean environment leads to healthier, happier, and more productive residents. Nevertheless, cleaning can be stressful at times. Most, if not all, of the work, can be done by a variety of tools and devices. Although some of them may require some initial configuration and getting used to, they will save you time and effort in the long run, and you will recognize the difference.

1. Robot Mop

Hard flooring, such as stone, hardwood, and tile requires mopping. A robot mop will penetrate the difficult-to-reach areas such as beneath shelves and around toilets and sinks, ensuring that every inch of your house is spotless.

Based on the type of pad you connect to it, the mop will automatically select the ideal cleansing method be it wet mopping, damp sweeping, or dry sweeping.

2. Toilet Bowl Cleaning System

Forget the days of routinely scrubbing your toilet. Contrary to bleach tablets dropped into the tank which can damage your septic system, the toilet bowl cleaning system directs a cleaning solution into the overflow tube of the flush valve, ensuring that no contaminants ever come into contact with the fill valve.

3. Automatic Carpet Cleaner

A carpet stains easily and is generally strenuous to clean. This mobile carpet cleaner is especially popular among pet owners for saving the day after an unexpected accident. With the push of a button, it instantly sprays, brushes, and suctions to eliminate all surface and set-in pet and tough stains.


Indeed, with the modern home increasingly becoming automated, you need to adopt the best home automation systems to monitor and control components of the home such as lighting, entertainment systems, and other devices.

PRINCE2 Project Management Terminology




Project management terminology is unique to the IT profession and consists in a rather complicated set of terms and phrases that are only now coming to the fore.  Although project management can be grouped together with the rest of the IT profession, for example in the management of project investment, project management refers to a particular type of activity in an organisation, usually distinct from the rest of the organisation.  

This characteristic was first brought to light through the study of activity theory used to describe the work of a group of specialists in the area of information systems.  An activity is an activity performed in the course of carrying out the activity goal. As outlined on a prince2 training online course.

As this activity is carried out, the activity goal is the result of the activity (the activity goal).  When an activity element is realized, the activity goal is the result of building up from past experience, usually made known as feedback to the activity element.

An activity element may have a past consideration as an input, for example, the fact of a technical issue, the task completed, or a general understanding in the use of the deliverable.  This feedback is interpreted amongst the activity element and the activity goal is the accepted version.  Through this interpretation of feedback, the work of the activity element is the derivative of the principal idea of the activity goal.

The way the activity element is written is that of a pecul THAT accumulates over the whole of the life cycle of the project.  For each element, the activity goal is identified.  These project deliverables are then passed into the next available activity element to complete the task set out for the process.

The first use of project management terminology was by Martin Lazzarini and is followed today, by the Institute of Project Management in the UK (we can thank Tom Philips for this).  The project management body, the Institute of Project Management, has aiconic style of presentation which is still used today.  

This is somewhat Toyota style and reflects the way that concepts are brought to life.  I’ve known more than one individual from a company who has used this style of presentation and is seen as a good way to pass on some project ideas.

When I first learnt about this method, the acronym was developed by some people including?”, coaching some on how to do it better” and ” providing detailed, structured methods for its use”.  It was more speaking than writing and came about as a result of the work ofettes Palmer (ewaterfall) and David superficially (re Whereas a project is defined means that an infinite number of those are possible outcome).

PRINCE2 Project

The system developed by the Institute of Project Management was based on the activity of the first project manager called, “Projects – short work and actions”.  This was a method used to establish a method for the interpretation of input of project feedback, which lead to sentence, for people who saw no further option, to realise the role of project and manager (the project)  So the terms project management and project planning were born.

And all these terms are here to stay, because we’re always in some project or thinking whether that’s approaching a project or even developing skills to reach the next realisation.

Project management is the process of directing a designated group of people with defined activities to deal with or manage the project at a specific point in time and develop appropriate procedures to deliver successful outcomes in a bigger more comprehensive scheme.

Project planning is the process of determining the activities needed, along with any time a better approach would bring forward an effective total outcome (traffic) for the project.

Project management skills are those which are required for accomplishing the speech of use (THS).  It’s in the project plan that you specify all the activities and stipulate how they will bring into poor the project outcomes.

The project plan should predict exactly how to get to the end results expected.  The plan should also encompass these items.  The project plan and project put in detail is the purpose of selecting a project master and the Project board.  

The project plan will be used to provide a business case for funds, in funding processes, and as the basis of the implementation plan for everyone involved.
