Robots depend on maps to move around. Although they can use GPS, it is not enough when they are operating indoors. Another problem with GPS is that it is not accurate enough. Therefore, robots cannot depend on GPS. Therefore, these machines depend on Simultaneous Localization and Mapping, which is abbreviated to SLAM. Let's find out more about this technology. With the help of SLAM, different types of machines such as robots create maps as they move around. With these maps, they move around without crashing into different objects in a room. It may sound simple, but this process consists of multiple stages that involve sensor data alignment with the help of a number of algorithms. These algorithms use the power of the GPUs of today. Sensor Data Alignment Today's computers consider the position of a robot as a timestamp dot on a timeline or a map. Besides, robots continue to collect data about their surroundings using these sensors. The interesting part is that camera images are captured 90 times per second for proper measurements. When robots move around, data points make it easier for the robot to prevent accidents. Motion Estimation Besides, wheel odometry considers the rotation of the wheels of the robot. The purpose is to help the robot measure its travel distance. Apart from this, they also use the inertial measurement units to estimate acceleration and speed. Sensor Data Registration Since data registration is done between two measurements on a map. Expert developers can easily localize a robot using scan-to-map matching. GPUs that perform Split-Second Calculations The speed of these mapping calculations is between 20 and 100 times per second. It all depends upon the algorithms. And the good thing is that these robots use powerful GPUs in order to perform these calculations. Unlike a regular CPU, a powerful GPU is up to 20 times faster. Therefore, simultaneous localization and mapping use powerful graphics processing units. Visual Odometry to help with Localization The purpose of visual odometry is to recover the orientation and location of a robot. Powerful GPUs use two cameras that function in real-time to guide the location at a speed of 30 frames per second. With the help of stereo visual odometry, robotic developers can figure out the location of a robot and use this for proper navigation. Besides, future developments in the world of visual odometry can help things make easier than before. Map Building that helps with Localization There are three different ways to create maps. In the first method, mapping algorithms work under the supervision dogood think of a supervisor. Therefore, the process is controlled manually. On the other hand, the second method involves the power of a workstation for this purpose. In the third method, odometry data and lidar scan recordings can help make things easier. With this approach, the log mapping application can help do the mapping offline. Long story short, hopefully, this article will help you improve your understanding of simultaneous localization and mapping. If you want to know more about mapping and localization, you can go to USPOT.report. They can also help you get familiar with localization patents. Universe is simply infinite. And even the nearest planetary and star systems are at tremendous distance. We just can't get there for now. But then, at least we want to watch it. See it. But I have seen people complaining "with a small telescope they can't see much!". And you too might agree on that. And you know what? They are right! They will never be able to see more than what they try for. This so-called beginner astronomers get discouraged, because they don't get the results they expected. Observing sky is not like spying your neighbors with binoculars. Its not that quick! A good sky observer is also good in patience and is able to stare through the eyepiece for hours. To be very very clear, improving telescope performance is not just about tuning scope. Off course its part of it. But you also need to tune yourself and your eyes. So in this article, today, you will learn some telescope hacks. I have found this to be most effective. This are the 8 simple DIYdailyeconomic buzz telescope improvement tips that works. So here are the few things which can help not just optimize yourself but your telescope as well. So you can see more and better: 1. Look for Clear sky There's no substitute to the clear sky. In fact it can indirectly add an extra inch to your aperture. Look up in the sky at day time for clues. Are there clouds? When the sun is over the head, block it with your hand and see if its clear blue around it. At the sunrise or sunset, make sure there are no clouds at horizon. 2. Avoid Light Pollution Pollution in no form is good for us. And when it comes to stargazing, the most hazardous one is light pollution. We usually observe the sky at night time. The simple reason for this, is because we need our surroundings as dark as possible. So that you can explicitly get to see the light coming from that cute little distant object. But in our modern society, there's light pollution everywhere. So its never gonna be a ideal spot. So what you have to do is go to a dark place. And it should be with least artificial light (eg. Street light etc). Going away from city is best when you want to see faint/far distant object. 3. New Moon is Good Aim for longer hours of observations especially on new moon. Try to have at least two session per week. 4. Let Your Eyes Adopt to Darkness Understand your eyes. They are on habit to brightness. So it will take some practice for your eyes to adopt to darkness. And your pupil to setup. When you start observing in dark surrounding. Make sure you don't see source directly (like phone, or light bulbs etc.). It will disturb the adaptation. Use red flash light if needed and still don't directly look inside it. It may take upto half an hour for your eyes to be at its 100% ability. 5. Keep Staring at it! You know what? There's a secret! To actually notice the details. Just keep staring at the object constantly through the eyepiece.briefly geek And as you keep on, the details starts to unlock. It may take a hour to enjoy the full view. Off-course, the time varies with distance from object. And you can take small breaks in between as you stare. But just don't disturb the concentration of your pupil with shiny things. 6. Thermally Optimize the Scope Its likely that when you put your telescope outside to start observations, it will be warmer than outside air. What then happen is, the scope radiates heat which can cause problem to viewing. So no matter how small your scope is, it's better togothits info allow it to collimate to outside temperature. For scopes upto 4 inches, it usually takes 20 minutes. And for scopes larger than 4 inches, add 10 minutes extra per extra inches. Usually reflector scope takes less time for the process than Refractor. 7. Stabilize Your Telescope Mount Hold it strong! As you zoom-in the objects, the tiny vibrations your scope makes, are also zoomed-in. Its a big problem when you zoom high. You just won't be able to see things at its best. They just won't look clear! Its usually a big problem with cheap, lightweight telescopes.art svent So what you have to do is to stabilize it. Suspend some heavy wight (like Backpack, or waterbottles etc.) to the tripod. Hope you got the clue! So get out there with your adorable scope. Follows all those tips I mentioned below. Get the experience you never got before. And let me know, how much you can see now and if there are any improvement? Just comment below for any anything you needed! Hey its Roshan Ingle.
