Memo: BreizhTech Company (who unfortunately ceased activity in july 2009) was established on May 2005 by Jean-Marc Desaulniers, Montreal Polytechnic graduated (Electrical Engineering- 1988) and Laval University (Biochemistry degree-1984). He has an international experience of 20 years in multimedia telecommunications, from R&D to Projects Direction. He held down the position of “Partnership Officer” for Alcatel mobile network division (North America) in his last job at Alcatel Lucent, and sales engineer. He was European Vice President of IMS Forum « Internet Multimédia Subsystem » in 2005-2006. His team consists of young engineers in France and Quebec in mechanics, optics, electronics and real-time embedded software. Several high-level personalities have joined him in 2007 in an « Advisory Board », helping him in strategic, marketing and financial terms. He has established partnerships with ebm papst (high precision motors), Thomson Multimedia (Futurimage Consortium), and a network of subcontractors for mechanical and optical realization. BreizhTech, Bretagne Entreprendre 2006 winner, has received support from OSEO Anvar from 2005 to 2007 (150 k€), and will receive assistance from Regional Council and Lannion-Trégor Agglomération (480 k€ in 2008-2009). JMDThèque Company (created in may 2007 by Jean-Marc Desaulniers) dedicated more specifically to R&D activities is now pursuing the R&D and Business Development effort initiated by BreizhTech, on every addressable market segments.

Application context:

  • Telecom link: base/beacons, beacons/mini-vehicles, mini-vehicles/GPS type (RFID, GPRS, WIFI/WIMAX, Satellite/GPS)
  • 2D/3D scanning with detection cameras mounted on mini-vehicle
  • Pre-listed plants recognition with specific system at the bottom of stems
  • Movement and noise macro detection
  • Profiles/signatures recognition (insects, parasites…)
  • Lock mode
  • Calculation of the beam energy/trajectory/impact zone
  • Validation and trigger mode for repulsive/incapacitating/destructive action
  • Return to the base to recharge and transfert of context to the mini-vehicle and to the server

Depending on the type of growing, pre-recorded plants calling for specific attention or care will be identified by each mini-robot by means of an adequate recognition system (with barcode authentication for example). These pre-recorded plants may have been, for example, particularly damaged after a pests’ attack or a harmful weather phenomenon (frost, hail…), and present more or less deep/extended wounds to treat as soon as possible. To ensure the integrity of these plants, the laser radiation could promote (by its inherent characteristics) disinfection/healing of these “vegetable” wounds just like some medical lasers used in the field of Health…

In the case of small areas to treat (< 1 ha), the “BlastHopperTM” will work alone in the land. A fixed base unit will be installed around the work area. It will allow the processing of data transmitted in real-time (robot position, signals of detection/localization, laser firing order, laser beam parameters…) and the electric recharging of the mini-robot’s battery (if necessary, note that the “BlastHopperTM” may be fitted out photovoltaic panels). The “BlastHopperTM” will automatically take control of the area to treat in getting its bearings through a constellation of location beacons regularly placed at the periphery of the explored area. These beacons will also ensure the data transmission (RFID, GPRS, WIFI/WIMAX) between the mini-robot and the base unit. Note that the mini-robot’s location can also be done by GPS. When the surfaces are larger (> 1 ha), a fleet of autonomous mini-robots will be put into action: each of them having a treatment area previously defined and delineated through the previously mentioned beacons or GPS. Each mini-robot will regularly return to the fixed base unit (or one of the fixed unit bases if the area is very wide) to recharge one’s batteries or make other possible maintenance.

Sized to be able to move easily along the cultures’ furrows (4-wheel drive or crawler device), the robot or mini-vehicle will also be equipped with an ultra-sensitive motion detection system (CCD camera and/or infrared detector and/or sound detector…) to locate precisely and quickly “target” insects/parasites on plants’ foliage, their stems and/or other parts particularly sensitive to pests. The device will be able to identify the type of located insect/parasite by comparing the collected signals with a database of different characteristic profiles/signatures (color, shape, texture) of a particular pest previously listed. Once the insect/parasite clearly identified, the target is locked and a precise laser shot is carried out through the DBE that receives in real-time informations collected by the detection/localization system. The different laser beam parameters (wavelength, power, pulse duration…) will be adjusted to each shot to take into account the type of targeted insect/parasite and ambient conditions. Depending on required needs/constraints of struggles, the user can define the action mode it wishes to use against pests: repulsive, incapacitating or destructive action.

The damages on crops by pests are of various kinds: they may be the result of the insects’ alimentation (both adults and larvae), their bites (transmission of viruses, destruction of tissues…), or their excretions (honeydew promoting the development of fungi). Note that each pest attacks a specific part of its host plant: leaf, stem, root, flower, fruit… at all steps of their development, including stored harvests products. Faced with these plagues, various methods (crops rotation, biological or chemical controls) are being used with more or less success...

According to these limitations, BreizhTech wants to develop the « BlastHopperTM »: an innovative low cost, laser device, with a great autonomy and environmentally friendly, to fight expeditiously against a wide range of insects/parasites pests (mode of action focused on a type of insect on particular or several types of insects simultaneously). This laser mini-robot will be equipped with the « Digital Beam EngineTM » ―DBE, one of the BreizhTech’s patented optomechatronic components. The DBE benefits of the latest technological performances in real-time software and embedded electronics, enabling an ultra-precise enslavement of adapted optical disks and high-power laser sources. The DBE is an innovative electromagnetic beams scanning system made with optomechatronical components developed in BreizhTech company.
  

Bio-agronomy: Multibeam laser scanning device against crop-destroying insects/parasites

A major challenge: an effective and lasting protection of various land under cultivation (cereals, vines  fruits, vegetables…) against insects and other pests the most possible respectful of the Environment… The laser technology may be a preferred solution to address this recurrent challenge at a time where Sustainable Development and Ecology are so important and present. Because of its exceptional intrinsic characteristics, the laser radiation is a promising alternative to insecticides, herbicides or fungicides used excessively, in order to significantly reduce harmful impacts for the Earth and living beings.

BreizhTech technology allows, via moving optomechatronic components, to operate synchronous laser multibeam scanning for high-accuracy and high-energy projection on predetermined surfaces. The Breizhtech’s technological break process consists in developing an innovative mini-robot called “BlastHopperTM” (and later a networking mini-robots fleet), fully automated and fitted out a laser technology to fight against insects/parasites pests on various types of agricultural lands (cereals, fruits, vegetables, ornamental plants and flowers…)
