22/06/2021 Husqvarna ‘Ceora’:
Today Husqvarna announced the introduction of the multi-purpose ‘Ceora’ robots for the maintenance of parklands, sports pitches and golf courses. The series consists of two models; the Ceora 544 EPOS and Ceora 546 EPOS and can maintain areas of up to 50,000m2 (12 acres).
The Ceora robots are considerably bigger than anything in the existing Automower line up. They measure 127 cm long x 108 cm wide x 44 cm high and weigh c. 70 kg. By way of comparison the largest Automower in the current line up, the 450X, which has an area capacity of 5,000m2, weighs in at 14kg!
The machine comprises two components – the power unit and a mowing deck.
The power unit is the rear part of the machine and houses the machine’s CPU, battery, wheel motors and EPOS (Exact Positioning Operating System) receiver. The Ceora 544 Epos and Ceora 546 Epos are physically identical, the differentiation is in the software which allows the 546 Epos drive a little faster and thereby increase that model’s area capacity.
Powered wheel brushes are fitted to the wheels of the power unit to sweep grass clippings off the wheels and ensure that no tufts of grass are left behind on the field.
There are three mowing discs under the 105 cm wide mowing deck of the Ceora which deliver a width of cut of 69 cm. There are five blades on each disc, the design of which is the same as on the existing Automower range. The machine’s height of cut, which ranges from 20 to 70 mm, can be controlled remotely by a smartphone or desktop app. The deck can be flipped up to allow easy access for changing blades and cleaning.
There are four sensors on the front of the mower deck. If these sensors detect an object on the grass, the driving speed decreases. If the object remains in the way, the Ceora changes its mowing route to avoid the object.
With a typical mow time on one charge of 4 – 5 hours and a typical charging time of 3 – 4 hours the Ceora 544 Epos has a daily mowing area capability of 20,000 m2. The Ceora 546 Epos meanwhile can handle 25,000 m2/day. If the robot has to return to an area only every second day, the machine’s capacity then doubles to 40,000 m2 to 50,000 m2.
EPOS (Exact Positioning Operating System)
The Ceora is equipped with the EPOS RTK-GPS system thereby eliminating the need to lay a boundary wire. Instead a reference station is placed near the area of operation. This station has a range of 500 meters. Thanks to the Epos system, the machine knows exactly where it is to within 2 to 3 cm. The EPOS system also controls the direction of travel – unlike the existing Automower range the Ceora mows in straight lines with an overlap of a few centimetres.
It is possible to set up to 20 different mowing zones. Each zone can be set with its own parameters such as mowing times and heights.
Post launch, Husqvarna expect to offer several tools that can fit on the front of the Ceora power units. Possibilities include a striping machine, grass roller, fertilizer spreader and a tool for collecting golf balls as well as alternate moving decks for mowing tall grass and low grass (e.g. fairways).
Guide Price & Availability
The Ceora 544 EPOS will cost approx. €25,000 including the charging station and the EPOS reference station. The Ceora 546 EPOS meanwhile will cost approx. €29,000 euros including the charging station and EPOS reference station.
The EPOS RTK-GPS radio signal uses a free band so there is no subscription costs.
The Ceora is expected to be available in the first quarter of 2022.
