As the drones continue to evolve at a breakneck pace, drones are getting smarter and advance day by day with some brand new sensors. Drones are becoming faster in processor and bring even more features to process data in real-time.
All the professional-grade camera drones have a new feature in it that is called drone collision avoidance feature. An essential feature in drones is the ability to navigate in real-time this feature has really the drones.
There is a build-in vision sensor serve the role as an additional layer of protection. This feature acts by scanning the object that is in the way of drone detects them and process the information back to its sensor, which makes the decision for the drone.
The drone collision avoidance feature is an incredibly powerful tool that minimizes the human pilot’s error. But that doesn’t mean that you should fly carefree, because it is possible to make a simple pilot error if you are not careful while flying the drone.
What is Drone collision Avoidance?
So here I’m going to tell you about drone collision avoidance. The definition of drones collision avoidance is the ability to avoid colliding with the other objects while flying the drone in real-time.
The drones with collision avoidance have a small sensor which engineers have mounted on its body framework.
But some drone as a way to advance that they have optical radar. This radar can see objects in a full 360 degree, but not all drones have these ability to do this some drones have limited senor field in view.
These sensors are a combination of light green to the dark green glass-like Lens found on the drone’s body. These Lens acts as the eye of the drone using infrared and ultrasonic scans to detect the objects as soon as possible.
This sensor is an incredible piece of technology that acts as an additional layer of protection for drones as well as the remote pilot.
These drones with collision avoidance sensor are brought by professionals but sometimes by beginners who want to fly these drones for commercial purpose.
This sensor helps the beginners to learn how to fly an advance drone without making any types of mistake while flying the drones because these drones are very expensive.
How does drone collision avoidance help the drone?
Now, this is the interesting part where I’m going to tell you about how these sensors work and how they help the drone to avoid collision with objects.
Basically, the obstacle avoidance system works as detection that automatically detects the object and collects its data. Then it sends all the data back to its motherboard using the information about how far the objects are.
If the sensors see that you are flying to close to the object, the processors will tell the drone not to fly any father close to it by turning the sensor barred. This sensor will provide you plenty of space to turn around your drones and avoid the collision.
However, this sensor can improve as well as the technology continues to evolve.
This feature is made for beginners because they don’t have enough knowledge to fly the drone without making any mistakes, but these sensors will help them to learn how to fly a drone safely. After all, you definitely don’t want to accidentally crash a 1000$ drone due to a simple human error.
These build-in sensors are quite potent on their own. They have the amazing capability that allows them to communicate with the organs inside the drones to avoid a collision.
But without these sensor drones will not able to see the object and are prone to human errors, and nobody wants to crash a $1000 drone because of a simple human error.
There are many types of drone collision avoidance sensors here I’m going to tell you about the three most powerful sensors in the market.
Types of Collision Avoidance Sensors
Stereo Vision Sensors for Obstacle Avoidance
This sensor works exactly like 3D sensing in the human vision. This sensor calculates the depth information by combining two-dimensional images from two cameras to form a different viewpoint.
After then, these images been identified that correspond to the same point in a physical scene observed by multiple cameras. The more clearly the image it is easier for the drone to detect the object.
The correlation stereo method obtains the corresponding pixels for each image that result in thousands of 3D values with every single image. Many companies use these sensors and combine the sensor with ultrasonic sensors underneath the drones for precise controls and safe landings.
Ultrasonic Sensors for Detecting Objects (Sonar)
This sensor is one of the best sensors in the world, and it is widely utilized in consumer drones is the ultrasonic sensor. This sensor takes the high-frequency pulse that measures the time how it long to take for the sound to echo back this sensors works through sound.
This ultra-sonic sensor has two openings. One of these transmits ultrasonic waves, and another one receives the ultrasonic waves.
As we all know the speed of sound is around 1,100 feet per second in the air. This sensor calculates the information that passes along the difference between sending and receiving to measure the distance to an object by using a mathematical equation that helps to measure the distance even faster.
Proximity Sensors for Obstacle Avoidance (Basic)
Finally, the proximity sensor is one of the inexpensive and simple features that is commonly added by toy grades drones.
These sensors are not advance as compared to ultrasonic and stereo vision sensors. The proximity sensors attempt to mimic in similar appearance by detecting nearby objects and avoiding the collision.
These sensors don’t create 3D images in the same way that stereo vision sensors do.
These sensors simply detect an object and stop the drone from flying in the flight path to avoid the collision and therefore providing an additional layer of protection to the drones. This sensor is an inexpensive way that enhances the flight safety feature system for beginners and remote recreational pilots.
Why buying A Drone with Obstacle Avoidance Feature is necessary?
There are two ways to answer these question yes and no. First of all, the drones that come with collision avoidance feature definitely do make flaying much safer and easier. Because these build-in sensors will not let you drone crash in some object.
It minimizes the error of the human pilot’s error compared to these popular toy-grades drones that are very easy to crash.
There is another reason for yes is that these sensors don’t guarantee protection for your drone. The sensor is smart enough to see the objects on its own. Sometimes objects are too small or thin that a sensor can’t detect it.
What happens next if your drone caught in a thin wire and briefly goes off-balance, this error would be considered a human error because the remote pilot isn’t paying attention. So you will need to be attentive to the drone’s flight path regardless of how smart the sensors are.
As the technology is getting evolve, engineers are making drones that don’t need any human pilot to control them just enter a route then these drones will automatically fly on this route. The sensor will automatically detect its objects and avoids the collision.
These drones are especially beneficial for businesses and law enforcement agencies.
Tips on which Drones with Collision Avoidance you should buy
For those who are unsure about buying a drone with a collision avoidance feature. Then I assure you that having a drone with collision avoidance detection system function is totally worth investing into.
Even if you are an expert in flying drones, you will understand why having a drone with that feature is very important.
There are many toy grades drones such as the bolt bee and ninja fpv that doesn’t come with collision avoidance feature. Yet they are likely to get crash and probably end up breaking into pieces if you somehow smash then hard enough.
They can’t detect the objects, and they will easily crash into something, and with a broken drone, you will be a very sad drone pilot.
A drone with collision avoidance detects the object and prevents a simple pilot’s error. Not just they can fly much safer they extend the life of the drone and makes your drone safer than ever these are one of the benefits of buying a drone with collision avoidance feature.
But some drones doesn’t have this feature and end up broken after a week or two, with this feature your drone will last for months even for years. So basically your investment is stretching into years rather than weeks.
So I prefer you to buy a drone with collision avoidance feature because this feature will protect your drone from crashing hence giving an extra layer of protection to your drone.
The drones with these features are perfect for the beginners they can learn to fly done without even crash them into the wood or any other objects. Drones with this feature are a bit expensive but worth investing.
From this, we can conclude that these drones are worth investing. Because of this feature, your drone will be safe and last for months and years.
This feature gives an extra layer of protection to your drones and helps you to fly save without crashing them.
As I can tell you by my own experience, these drones are perfect for the beginners they can learn to fly these drones without crashing them into the woods and into any objects.
So keep in mind to buy a drone with collision avoidance feature.
