Localization Systems

Localization Systems

In order to get a mobile robot functioning autonomously, you need localization systems specifically designed for your purposes. Whether you need the mobile robot to function indoors, outdoors or both.

Avular has developed localization systems for all kinds of mobile robotic applications designed to operate on land, on water or in air. For every use-case, we have a navigation solution for you. There are three Avular localization systems available: Stellar, Avular’s most accurate system which works with Infrared light, Spectrum, Avular’s Ultra-Wide Band system, and Starling, the Real Time Kinematic GPS system by Avular. Each is developed for specific applications.

- For indoor applications with plenty line of sight
- For extremely accurate measurements of position and rotation
- For applications that require high robot speed

- For outdoor applications that require accurate positioning
- For applications with minimum amount of beacons

- For indoor applications with limited line of sight
- For robots that are used both indoors and outdoors
- For applications that require mobile beacons
- For any application where Stellar and Starling are not an option


Starling (IR)

The Avular Starling system is developed completely in-house. From its concept to design, from assembly to testing. Its biggest advantage is the unmatched high accuracy of its measurements. When compared to ground truth, it’s shown that Starling is accurate up to 1 to 1,5 centimeters.

Stellar (RTK/GPS)

The Avular Stellar system works with real-time kinematic GPS (GNSS). It uses – like any GPS system – the satellites to know its location, but also uses GPS information sent from a base station with a known location. This makes the Avular Stellar accurate up to 2.5 centimeters and perfect for applications outdoor.

Spectrum (UWB)

The Avular Spectrum system uses ultra-wideband technology and is suitable for both indoor and outdoor applications. Its beacons function as satellites, communicating with the mobile robot. By measuring the travel time of the signals, the robot can calculate its distance from the beacons and therefore its position. It is accurate up to 20 centimetres without needing line of sight.

Vertex

Vertex


The Vertex is the ultimate drone platform to develop new applications with. The platform is built in an open, easy-to-access way, which enables our customers to fully customize the drone if desired.

The Vertex is perfect for customers that want more than a simple standard drone. From autonomous flying to adding new, customer-specific sensors and from generating data to path planning – this is where the Vertex shines.

Seamless integration navigation purposes

The Vertex seamlessly integrates with our various localization systems such as Avular Stellar and Sterling. Only for the Vertex, we have added the Avular Spectrum module to the Vertex. This means our customers only have to purchase the beacons of the Spectrum system. For all Avular navigation systems, the MATLAB Simulink blocks are provided as well as the binaries for ease-of-use, which makes programming more time-efficient.


Scalable design

Because the drone is made in a modular way, the drone can easily be upscaled towards a bigger drone, for example for heavier lifting. The processing power and software can stay the same, so only mechanical changes are necessary. With Avular Services, our team of highly-skilled engineers can make this for you. Since we know all the ins and outs of the Vertex, we work time-efficient and cost-saving.

Easily customizable

The Vertex is designed to be a drone that is suitable for every drone purpose, for every customer looking for a flying solution. Easily attach new hardware such as LEDs, sensors or actuators. The Vertex enables drone applications for companies that don’t have the resources to build a drone themselves, but cannot work with closed and limited-functionality drones currently available in the market. Our customers can add their expertise to the drone, turning it into a solution to their specific problem. Its open structure allows measurements to be read and exported, so it can be compared to and integrated with existing data.


From the design table to the sky

The drone in its entirety is designed and developed in-house by our multi-disciplinary team. From mechanical designing to software and electrical engineering to eventually control technique. Avular has years of extensive knowledge about drones and control for mobile robotics, which is bundled together in the Vertex.


Autonomous indoor flying

Unlike many other drones on the market, the Vertex is exceptionally good at autonomous indoor flying. Of course, the Vertex can be used for outdoor applications as well. Even flying autonomously from outdoor to indoor is no problem for the Vertex.

Avular-Spectrum

Avular Spectrum (UWB)


The Avular Spectrum system uses ultra-wideband technology and is suitable for both indoor and outdoor applications. Its beacons function as satellites, communicating with the mobile robot. By measuring the travel time of the signals, the robot can calculate its distance from the beacons and therefore its position. It is accurate up to 20 centimetres without needing line of sight.

Suitable for every application

Since the Spectrum system uses ultra-wideband technology to communicate with beacons, it can ‘see’ around corners and through objects. This means it can even operate beyond line of sight and that makes Spectrum suitable for every application. A minimum of 3 beacons is needed for a 2D position of the robot and a minimum of 6 beacons is ideal for 3D mapping. The beacons are mobile and can be (re)placed whenever needed.


Fleet compatible

Spectrum can be used both indoors and outdoors. Its range is around 80 to 100 meters, so our customers don’t need many beacons to get a location covered. The number of beacons can easily be scaled up and there is no maximum to that. The number of coupled mobile robots can also be scaled up, making it possible to use it as a navigation system for a robotic fleet.


Combine systems for the best of both worlds

Since every navigation system is developed for specific purposes, customers might want to combine some systems to gain all advantages and skip their limitations. That is possible with all Avular navigation systems, but also with third-party products. For example, combine our Stellar, Starling and Spectrum to navigate a mobile robot both indoors and outdoors. Or combine a third-party lidar system with Avular’s Spectrum to have Avular’s accuracy and speed, with their safety and certifications.


Auto-calibrate functionality

The Spectrum beacons can measure and calibrate their own positions automatically. Simply place the beacons, open Avular Cerebra and select ‘auto-calibrate’.


Avular-Stellar

Avular Stellar (RTK/GPS)


The Avular Stellar system works with real-time kinematic GPS (GNSS). It uses – like any GPS system – the satellites to know its location, but also uses GPS information sent from a base station with a known location. This makes the Avular Stellar accurate up to 2.5 centimeters and perfect for applications outdoor.

Up to 2.5 centimeters accurate

To provide higher accuracy than standard GPS, Avular Stellar uses one base station that is updated with its exact location (with coordinates). The base station provides its exact location and received satellite signals to the robot, and the robot compares this information to the GPS signals the robot received from the satellites. It then locally calculates its location up to 2.5 centimeters accurate.


Ideal for outdoor applications

Because the Avular Stellar uses GPS for navigation, its ideal application area is outdoors on open fields and large outdoor spaces, where it has access to enough (min. 4) satellites. It can’t flourish indoors, since the GPS signals from the satellites won’t be strong enough.

Or combine a third-party lidar system with Avular’s Starling to have Avular’s accuracy, with their safety and certifications.


Long and expandable range

The Stellar base station has a range up to 500 meters, but can be expanded by adding more Stellar stations. This way, the mobile robot can use the next station before losing signal.
