After popularising boundary - wire free robot lawn mowers with the likes of theSegway Navimow i105 , the fellowship is back with bigger , more powerful modelling with the X3 series .
Segway ’s previous automaton lawn lawn mower were plan to get by with small to medium sized gardens , but the X3 reach is build for larger , more complex lawn , as well as offer significant upgrades to the navigation and obstruction shunning systems .
EFLS 3.0 navigation
As with Segway ’s premature robots , the X3 serial publication does n’t require boundary conducting wire , using the society ’s Exact Fusion Location System ( EFLS ) . Upgraded to version 3.0 , this system of rules immix the GPS - establish Real - Time Kinematic ( RTK ) arrangement along with the tv camera - based Visual Simultaneous Localisation and Mapping ( VSLAM ) , and Visual Inertial Odometry ( VIO ) technology .
With the RTK system , the golem still requires a separate character post to be installed , which is distinctive for robots like this . For the X3 Series , the RTK organization has been updated to a three - absolute frequency system of rules , which the company say increase signal reportage by between 20 and 30 % , helping boil down blind place because of poor reception , such as in narrow-minded passage or under covered orbit . In addition , two reference stations can be installed , allowing extended coverage .
Husqvarna has managed to get free of the want for credit stations with its latest merchandise , such as the Automower 305E NERA by using the cloud - based web RTK system . With this , the chastening data , which ensures precise GPS positioning to within a distich of centimetres , is sent via Wi - Fi rather than via the reference station .

It ’s a engineering that Segway is looking at .
Calvin Chen , president and CTO of Segway Navimow , explained that the society was looking at web RTK and would incline a “ beta programme for chiliad of customers ” of the X3 Series .
Chen say that using internet RTK has a annual cost to the company , and that cost would have to be paid by customer , although the beta test would be provided for complimentary . With a reference work place , RTK can be offer for barren .

Arguably , reference stations are serious for large properties with more complex layouts , providing more accurate emplacement , whereas internet RTK feels like a more interesting technology for pocket-sized gardens , where there ’s less space and client need to get running faster .
In addition , the robot ’s three photographic camera ( one at the front and two at the side ) can be used to aid navigation in areas where RTK might not work so well , such as go along a small pathway .
New VisionFence
VisionFence is Segway ’s camera - base object detection and avoidance system , and the X3 Series features an upgrade rendering that utilise three camera for a 300 ° scene , plus a Time - of - Flight ( ToF ) detector .
The ToF sensor facilitate the robot go out how far forth an obstruction is , with a 0.1 - to-2 - metre range of mountains . Cameras are used to discover what kind of obstacle is onward , and the X3 Series can find over 200 obstacle type , include masses , dog-iron , quat , wild beast ( such as Erinaceus europaeus ) , and common things in the garden , such as balls , chair and tables .
We ’ve been impressed with the system in the past , which has helped Navimow golem lawn mowers capably navigate cluttered lawns without guide into objects .

Expansion port
An expansion port on the side of the automaton lawn mower countenance the robot take succeeding climb . At the launching , a grass trimmer was demonstrated , which allows the X3 Series to contract justly to the boundary of a property , but this accessory will not be uncommitted in the UK .
Chen explained that for safety reason , the trimmer ca n’t operate all of the time and requires “ a bush button in the app ” to betroth . As such , Segway Navimow is trialling the trimmer in some countries but would ultimately like a solution that ’s amply automatic .
There are other possible uses for the expansion port . For instance , many the great unwashed fertilise their lawn twice a yr , and Chen says that ’s a job that an expanding upon twist could potentially undertake .
Better performance
Segway has kick upstairs the trend deck to bear six blades , and has used an anti - obstructive sword disc . The mower can also cut grass faster . Previous models operated at up to 0.5m / sec , but the X3 Series can cut at up to 1m / sec .
Able to cut up to 5000 m² in a twenty-four hours , the X3 Series can cut up to 1200 m² using a single barrage fire charge . fast charging means that a 30 - minute cathexis lets the robot handle 500 m² of lawn before it require to rejoin to the sorrel .
Other raw features include a dot matrix screen that shows status updated , theft alert in the app if the lawn lawn mower is lifted , GPS tracking , and a conception that can handle side of up to 50 % .
Versions and pricing
There are four model in the X3 Series phone line - up . The X315E can handle lawn up to 1500 m² , the X330E lawns of up to 3000 m² , the X350E lawn of up to 5000 m² and the X390E lawns of up to 10,000 m² .
Pricing is £ 2,199 for the X315E , £ 2599 for the X330E , £ 3199 for the X350E and £ 4299 for the X390E.
