Importance of Simultaneous Localization

As far as robotics is anxious, that technology is quite advanced. However, one large problem that experts face is mapping and localization as much as robotics are involved. This is where SLAM relates to the rescue. In this article, we intend to take a look at the need for simultaneous localization and mapping. Read on for more information.

Introduction to SLAM

Basically, SLAM is an excellent alternative to GPS and works somewhat similarly. This technology guides robots to be able to be aware of the surroundings and come in the right direction while performing their functions. Although GPS is an excellent mapping system, there are a few hurdles when it comes to its functionality.

Due on the limitations of GPS, experts now use simultaneous localization and mapping. This technology has proved to be a great option to GPS because it offers a wide range of advantages.


Since robots feature memory banks which may have huge capacities, they are able to continue to map their location using SLAM. Apart from this, GPS doesn’t guarantee a precise position in the robot. However, where positioning is involved, SLAM is best choice. It aligns sensor data on multiple levels for developing a map.

If you believe that this alignment is not a big problem, you must think again. The sensor data passes through alignment over a number of levels. This multi-level process employs a wide range of algorithms. Since this form of processing is pretty complex, it needs the power of today’s GPUs.

SLAM might help solve a lots of problems on earth of navigation and mapping. For example, this technology will help drones and robots find their way in a very closed environment. This is especially more useful where GPS technology cannot work correctly.

Actually, SLAM figures out and determines position and orientation for robots with respect for the objects in proximity.

Cameras, Sensors, and Data

As far as data collection is worried, SLAM systems use multiple cameras. Based on this consolidated data, the device can create maps for convenient navigation. Besides, with the aid of sensors, you’ll be able for robots and drones to take pleasure from a greater degree of accuracy and sturdiness. Therefore, the appliance can perform well during adverse conditions.


With the assistance of these technologies, cameras require 90 images per second. Besides, additionally, they record a wide range of LIDAR images. Therefore, robots and drones could be much better alert to their surroundings.

Different systems start using thise images for plotting and mapping efficiently. Since these calculations require supreme processing power, special graphic processing units bring maximum performance. These units are classified as GPUs, that happen to be used in computers for rendering videos and doing offers.
