    • Early Tests of the WikiLauncher First Stage 

      Tristancho Martínez, Joshua; Tarazona Romero, Andrea (2013-05-03)
      Report de recerca
      Accés obert
      This is a technical report for the early nine test of the first stage of a minilauncher to put up to six femto-satellites in a 250 km Low Earth Orbit. These nine tests were performed in a stone quarry in order to gain ...
    • Implementation of a femto-satellite and a mini-launcher for the N Prize 

      Tristancho Martínez, Joshua (Universitat Politècnica de Catalunya, 2010-05-20)
      Projecte Final de Màster Oficial
      Accés obert
      In this Master Thesis we begin with a short analysis of the current space market, with the aim of searching solutions that allow us to implement femto-satellites (that is, satellites with a mass less than 100 grams) and ...
    • Innovative NDT technique based on ferrofluids for detection of surface crack 

      Rojas Gregorio, José Ignacio; Cabrera, Blai; Musterni Girbau, Gerard; Nicolas, Jorge; Tristancho Martínez, Joshua; Crespo Artiaga, Daniel (2015-11)
      Article
      Accés obert
      An innovative NDT technique is proposed for surface inspection of materials not necessarily magnetic or conductive, based on local magnetic field variations due to ferrofluid deposited in the cracks. The feasibility of the ...

      Text en actes de congrés
      Accés obert
      Es descriu una experiència formalitzada d’aprenentatge cooperatiu mitjançant la utilització de la metodologia del puzle. Concretament, s’utilitza el puzle com una eina de suport en una assignatura organitzada d’acord amb ...
    • Service oriented fast prototyping environment for UAS missions 

      Royo Chic, Pablo; López Rubio, Juan; Tristancho Martínez, Joshua; Lema Rosas, Juan Manuel; López, Borja; Pastor Llorens, Enric (2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper introduces a simulation architecture to evaluate the implementation of a va- riety of civil UAS missions with little recon guration time and overhead. This architecture, called Icarus Simulation Integrated ...
    • Simplified Femto-satellite Operations for Disaster Management Missions 

      Tristancho Martínez, Joshua; Gutiérrez Cabello, Jordi (2012)
      Text en actes de congrés
      Accés obert
      The reduction in size of satellites is reaching at the range of femto-satellites, i.e. satellites less than 100 grams in mass. One of the key points to achieve such a reduc tion is to simplify the design of the satellite, ...
    • Spherical Rover for lunar and planetary exploration 

      Gutiérrez Cabello, Jordi; Tristancho Martínez, Joshua (2013)
      Text en actes de congrés
      Accés obert
      Historically, planetary and lunar rovers have been wheeled-driven. While this is usually seen as an advantage –due to the flight experience– in some cases, the unavoidable presence of gears and mobile parts can be a ...
    • Tensegrity ring for a sports arena formfinding and testing 

      Peña Villamil, Diana Maritza; Llorens Duran, Josep Ignasi de; Sastre Sastre, Ramon; Crespo Artiaga, Daniel; Tristancho Martínez, Joshua (2011)
      Text en actes de congrés
      Accés obert
      The current prototype’s key contribution to the field of light-weight structures is that it is the first time that a pure tensegrity ring has been used in place of a compression ring. This design features a cladding ...
