This 4 degree of freedom version is designed to follow any trajectory as a typical torpedo-like AUV, but adding the capability of very short-range manoeuvers (on spot).
June 2007: Perrone Robotics AUV Sweden moves to new facilitiesThe new location, 200 meters from the nearest lake and less then 1 km from the sea, is strategically positioned between Stockholm city and it's archipelago.
April 2007: Upgrading Raia3.3 to Version Lambda (4.0)The design of Raia3.3 was very good from the hydrodynamic point of view but the thrusters, located too close to the cameras, limited the field of view and added turbidity during close-up operations. In the Lambda Version the thrusters has been repositioned without affecting holonomy and increasing dependability in narrow environments. The summer will be dedicated to water tests.
March 2006: Oi06 ExCel LondonThank you for visiting us at Oi06 in London ExCel UK. Having spent too much time in propeller and thruster design we failed in bringing our platform to the exhibition. Despite this was a rather silly mistake, knowing how advanced the development of Raia3 is at the moment, we could plan an autumn tour in Europe visiting our potential customers. Raia3 will be displayed in your own waters and you will be able to see if really fits your needs in your environment. Contact us as soon as possible to book a demo at you place if you are interested and we will add your location to our already quite long tour list.
November 2005: Raia upgraded from version II to 3The thrusters were very good but not optimized. A new design was decided to improve the hydrodynamics. The propellers will be redesigned together with their duct for the optimal cruise speed (1.2 m/s). The fiber optic cable has been bought: 500 m tactical GOF cable (multimode).
October 2005: Perrone Robotics member no. 169 of EuronFollowing the suggestion of Professor. Henrik Christensen head of CAS at KTH Stockholm, Perrone Robotics applied as a member of the European Research Network www.euron.org After one month of evaluations the company has been declared eligible and became proudly member number 169.
June 2005: Oceans05Europe BrestThis has been the first public appearance of Perrone Robotics and our main AUV platform Raia II. After the recent re-location of the thrusters Raia passed from version I to version II. This new position allows more agility still maintaining holonomy as the main feature of Raia. Unfortunately the platform was not completed and it has been shown partially assembled. Despite the rugged look most of the visitors of boot 1.29 could recognize a high quality mechanical design and construction, and were pleased of the originality. Many are waiting too see our developments: we will not disappoint them. Thank you all for your support.
March 2005: Raia from version I to IIReconfiguration of thrusters position: more slender design achieved. Another brilliant idea of Pipin. The lithium polymer battery is bought together with the power network components. The two firewire cameras have been bought and will be installed not inside the hull as planned in the beginning but outside in separate housings.
September 2004: Perrone Robotics moves the laboratory to new locationThe lab is moved in a 60 sqm workshop just 15 minutes away from home. Much easier to switch from design to construction.
June 2004: The providers network is builtRaia's hull is completed and few components have already been chosen and bough. Among them the pressure sensor and the inertial sensor.
November 2003: Giuseppe "Pipin" Parodi helps outFrom drawings to first model, and water tests (drag coefficient estimated) help was needed and Pipin with his long experience in mechanical design and construction made most of the things possible. Determined to use composite reinforced plastics and willing to learn a technique that could allow the manufacturing of a totally scalable product, few weeks has been dedicated in developing the moulds for Raia. Due to the volume of the hull (implying weight if neutral buoyancy is wanted) the "large" size (80 cm diameter) was abandoned; we focused on the medium size instead (60 cm diameter).
June 2003: The first holonom AUV has been designedIt will be called Raia which means Ray fish in Latin (and Portuguese). At the moment is just a drawing on a piece of paper.
March 2003: The company is activatedDue to the limited budget, the company has to pass the winter underground, but now spring is here and we can finally flourish.
September 2002: Perrone Robotics is bornOur motto is: Leave things better than you have found. We love robotics for gathering all the sciences we like, and we love the seas: let's try doing something useful.
