The mechatronic design of a micro-autonomous underwater vehicle (µAUV)

Abstract

Ford, GM Team Up on Transmissions-General Motors and Ford Motor Co. are preparing to jointly develop nine-and 10-speed vehicle transmissions to help them meet future fuel economy standards. Although neither has yet made a formal announcement, the two automotive giants have signed a memorandum of understanding that would enable them to work cooperatively on transmissions that might be ready for production as early as 2015. Sea Turtle Robot Will Swim Autonomously-We've seen a robotic tuna and robots that swim more or less like people. Now engineers at the Swiss Federal Institute of Technology have built a robot modeled on a sea turtle. Toyota's Latest Robot Lends a Hand-Toyota has developed a new robotic personal assistant that can help the elderly or other people with limited mobility who may need an extra hand doing things around the house. Gesture Sensors Could Help Mechatronics Engineers-A recent announcement from a company that specializes in sensors used for gesture detection sparked thoughts about using this type of control in mechatronic devices. The company mentioned using gesture controls in TV sets. That type of control works for interactive games, too. Ford, GM echipa pe Transmisii-General Motors si Ford Motor Co se pregătesc să elaboreze în comun transmisii de vehicule cu 9 si 10 viteze pentru a le ajuta să îndeplinească viitoarele standarde ale economiei de combustibil. Desi nici unul nu a făcut încă un anunţ oficial, cei doi giganti auto au semnat un memorandum de înţelegere care să le permită să lucreze în cooperare pe transmisii care ar putea fi gata pentru producţia încă din 2015. Robot broasca testoasa va înota autonom-Am văzut un ton robotizat şi roboţi care inoata mai mult sau mai puţin ca oamenii. Acum, inginerii de la Institutul Federal Elvetian de Tehnologie au construit un robot modelat ca o broască ţestoasă. Robotul cel mai recent al Toyota dă o mână-Toyota a dezvoltat un nou asistent personal robotizat, care poate ajuta persoanele în vârstă sau alte persoane cu mobilitate limitată, care ar putea avea nevoie de o mână suplimentara pentru a face lucrurile în jurul casei. Senzori de miscare a mainii ar putea ajuta Inginerii Mecatronisti-Un anunţ recent de la o companie care este specializata in senzori utilizati pentru detectarea miscarii mainii a stârnit gânduri despre folosirea acestui tip de control în dispozitivele mecatronice. Compania a menţionat utilizarea controlerelor de miscare a mainii în instalatii TV. Acest tip de control funcţionează de asemenea pentru jocuri interactive.

Propelled microprobes in turbulence

“…In the oceanographic and meteorological context, field measurements of fluid velocity and scalar field intensitiessuch as temperature or concentrations of bio-geo-chemicals -are often performed by means of drifting instrumentations either self-propelled or pulled by moving vehicles. We refer for instance to the instrumentation used to perform the very first measurements of turbulence spectra in a open water flow, which was presented in the pioneering paper by Grant et al [1], or to the vast literature on autonomous underwater vehicles (AUV) [2,3] and their latest miniaturised versions (µAUV for micro-AUV) [4][5][6]. In all the above mentioned cases the probe positions always trace paths across the spatial domain which are the result of the interplay between the direction and intensity of motion imposed by the engine (or by the pulling system) [7] and the strength and orientation of the local sweeping of the fluid flow.…”

Brief Analysis of Underwater Movements of Spherical Robot

“…This robot was employed 6 propellers as propulsion system which were equipped on the equator of the spherical hull. The development purposes of this micro robot were monitoring the nuclear storage ponds and waste water treatment facilities to prevent leakage [9] . Due to the importance of hydrodynamic characteristics, a lot of researchers did study on spherical underwater robots.…”

Trajectory-Based Visual Localization in Underwater Surveying Missions

“…This paper describes our proposal for EKF-based visual localization, which is mainly addressed to mid-scale surveying underwater missions in shallow waters or in environments with a limited space for maneuvering (for instance, monitoring nuclear storage ponds [ 18 ]), using low-cost mini or micro-AUVs with limited computational resources. The proposed approach integrates the data provided by different sensors in an efficient manner to elude the aforementioned problems and to provide accurate pose estimates in real time.…”
