Introduction Hunveyor and Husar space probe models are the main school robotics program in Hungary in the last decade initiated by our Cosmic Materials Space research Group (CMSRG). As a new form of planetary science education in Hungary students build their lander and rover robots and test them on test tables, carry out simulations, and go with their instruments to field works of planetary geology analog sites. Recently 10 groups work in this program and here is a status report about the new results. Planetary robot construction and simulations steps We summarized in 10 steps the main "constructional and industrial research and technology" description of planetary material studying and collecting by space probes (landers, rovers). We focused on the activity we began and teach to carry out at those steps. (Main planets considered were the Moon and Mars): 1. Reconnaissance and survey of the surface of a planet by orbital space probes (i.e. Lunar Orbiter, MGS, MRO etc.) Our studies: photogeology, geomorphology, preparations to cartography. 2. Mapping of the surface of the selected planet with geographical and stratigraphical methods. We (CMSRG) prepared thematic maps on Moon, Mercury, Mars, Venus [1] and Atlas (3) in the series [2,3]. 3. Identification of various surface materials by albedo, spectroscopic [4], thermal IR, identification and selection of the target sites. (in terrestrial analog sites during field works) 4. Planning the space probe system lander and rover working together (MPF-Sojourner type assembly). Planning of the Hunveyor and Husar models. 5. Construction and manufacturing lander and rover units. All Hunveyor groups built their models [5]. 6. Launching and traveling the space probes to the planetary surface. (No rocket building, we simulate [6] some events during the voyage only). 7. Measuring the planetary surface environment on the surface of target planet [7]. (CMSRG) groups carry out test-table measurements [8] and simulations, and later they go to geological type planetary analog field works in terrestrial conditions [9]. 8. Transmitting data. At CMSRG groups at field observations to the "terrestrial control" receives data. 9. Studies on planetary material samples. We can study real NASA Lunar Sample, real Hungarian and NIPR meteorite samples. 10. Comparative planetology. CMSRG's outreach studies are summarized in the Concise atlas series notebooks. Husar-2 rover developments The Husar-2 developments of the Pécs University were focused on a rover type to use it in the MDRS program. After systematic developments of Husars from LEGO Husar till the Husar-2a, -2b, -2c variants the final version Husar-2d visited the MDRS crew 71. in Utah, USA in 2008. Two years ago H. Hargitai used Husar-2b in Utah, in the works of the MRDS crew 42. where dry badlands surface forms are excellent analogs to Martian landscape. Hunveyor-4 ice surface visitor The new developments in Hunveyor-4 focused on the winter Balaton surface measurements. The triangular arrangement for the measuring arrangement of the three sound frequency range sensors with a hanged on hydrophone was planned [7]. Husar-5 developments The Husar-5 developments focused on LEGO modelling, and one measurement is for soil vibrations, the other is for the conductivity of the soil. It is in construction at Széchenyi István High School, Sopron. Husar-6 developments The Husar-6 is another LEGO based modelling, built at Zsigmondy Vilmos High School, Dorog. Hunveyor-9 and Husar-9 It is one of the newest construction at the Eötvös József High School in Tata. The Hunveyor-9 have been built with camera and a telescopic arm instrumentation, and a magnetic carpet experiment. Magnetic carpet is a sensor of the magnetic components of a planetary dust mixture transported by the wind. The mixing ratio of the magnetic and nonmagnetic components were measured with various slope angles of the carpet unrolled from Hunveyor-9. Hunveyor-10 The Neumann János Computer Science Society developed the last Hunveyor system. It was a meteorological station with 14 measurements. It represents a halfway Hunveyor, because of the building together of the instruments can be studied in this system. It was transported by the Crew 71 to the MDRS and two weeks of measurements were carried out in Utah, during 2008 April (with Husar-2d field work, too). Summary Several new developments of the Hunveyor-Husar university robot system were shown to mark the intensity of interest of students to the preparations to the field work research in planetary geology by building robotics and use them in field works.
