What is the “chaos” principle when navigating?
The name comes from the fact that the driving around the robotic vacuum cleaner for an unbiased observer sometimes “messy” look. In the “robot-technical language” speaks of it instead as an ” amoeba strategy ” or random driving strategy .
They recognize such driving behavior because the robot so long travels straight until it encounters an obstacle. He turns up to an angle which is “almost” by accident, only the length of just worn straight path is included in the calculation of Abdrehwinkels.
Yes, the random driving strategy is merely an extension of the amoebae strategy: the robotic vacuum turns his direction not only after a collision (at the room walls or other objects), but according to an estimate by him maximum term he recalculated after each collision.
Manufacturer and seller of robotic vacuum cleaners take both but often under the umbrella term “random” together. The random driving strategy results in a slightly worse coverage than the (simpler) amoebae strategy.
This is actually the one driving strategy, the one still feels the most appropriate and rational when you watch a robotic vacuum cleaner at work: here webs Namely worked in exactly parallel applied straight. At least the robot tried. The attempt would be successful if the cleaning object in front of him would be a completely empty room with smooth floor.
The Mäanderstrategie superior amoebic strategy in this case, clearly, if only because through it the area is completely processed in considerably less time.
However, reality usually looks quite different. Not everyone lives in a vacated Turhalle, and Japanese furniture design is not to everyone’s taste. Instead, the robotic vacuum cleaner has to reckon with all sorts of obstacles that can stop him from his path. So already are small doorsteps or carpets able to bring the robot “out of sync”. Or he meets a particularly smooth place on the floor and swung suddenly to the side. In all these cases it would have to correct its infrastructure in order to go straight again and to achieve the planned coverage.
Robotic vacuum that work with the Mäanderstrategie, therefore have an additional Visionary Mapping ™ System , which is filming the ceilings while working and with this information the robot repeatedly on his straight (and especially parallel) paths forces.
The navigation option “spiral drive” is used by modern Saugrobotern only in special situations ( Vileda 142861 Relax ). Typically, the robotic vacuum is set at a certain point in the room on the floor and started with this mode.
He then works its spiraling outwards forward until he has executed a circular area of a certain diameter (usually about 1 meter) or hits an obstacle and then continue its journey in straight paths.
Robots that have no charging station, from where they start and they also return automatically, use the scroll drive mode on boot.
But the Roomba from iRobot behave if you do not start from the home-base of. All robots set the spiral drive in so-called. SPOT mode a.
Incidentally, there is an important difference between the spiral drive when amoeba system and those with a meander system: made in the latter, the spiral arms of individual, ever-lengthening straight track sections while they are genuine curved paths at Amoeba systems.
