10th IFAC Sympsium n Advances in Cntrl Educatin Sheffield, UK, August 28-30 2013 Lw-cst platfrms used in Cntrl Educatin: An educatinal case study E. Irigyen, E. Larzabal, R. Prieg Autmatin and Engineering Systems Department UPV/EHU, Spain
Outline Why think in lw-cst platfrms? Subjects cntents Students interest Easy accessibility Tw criteria fr selecting these lw-cst platfrms. Prpsals in UPV/EHU NXT - Arduin - Raspberry Pi - Kinect Cnclusins
Why think in lw-cst platfrms? Increase and imprve learning cntent related t Cntrl Educatin Capabilities and interest f students Lw cst... even fr students
Learning cntents Increase and imprve learning cntent related t Cntrl Educatin Transitin frm theretical appraches + develpments t learning by practical + real develpments. Withut remving analytical part, strengthen learning with real applicatins. New" teaching prpsals Beynd PCs and simulatins
Students: capabilities & interest Achieving the cnvergence in: capabilities and interest f students New technlgies are assimilated fr students faster than tutrs r teachers. Using real platfrms increases the pssibility f theretical and practical learning
New platfrms accessibility Lw-cst Investment in labratries r classrms. Cmplementing the "classic" mdels.... even fr students. Curiusly, befre preparing wrks related t these platfrms sme students had previusly bught them fr playing and implementing their slutins at hme.
Our prpsal Practical wrks Independents: Withut guidance Outside f labratry regular time table Giving general bjectives t btain services / system behaviur / final achievement Advantages and stimuli Thinking in a cmpetitive envirnment fr stimulatin f students interest. Evaluating as a cmplementary grade fr the curse Mre clse t the real slutins further frm the simulatins
Selecting lw-cst platfrms Tw criteria: The particular cncern f the teacher t include mre didactic cntents in curses and subjects The cntinuusly grwing experience f students in relatin t every lw-cst platfrm

LEGO NXT Student develpments Subjects: RTOS Perceptin Systems http://www.yutube.cm/watch?v=tlcvtbavg_c Final career prjects Participatin n the cmpetitin f GT CEA de CI http://www.yutube.cm/watch?v=3w6mwts_syc Science week Engineering wrking days: Segway + Jhnny 5
LEGO NXT Handkerchief game Surface fr cmpetitin: A black square surface (1x1 m) with a white line (1 cm f width) Rules Each rbt drives ver a white line until the target, catch it and turn back t the start. All rbts have t be designed and created by students withut any help frm their teacher.

and next? Is it necessary t limit these wrks t the previusly presented platfrms? N why? There exist ther platfrms less knwn (amng thers): Skybt Be-bt Prtbt Dweng bard New platfrms will appear in a next future
Cnclusins This wrk deals with tw questins: What lw-cst platfrms select fr teaching in Cntrl subjects. What new schedule cnfigure in rder t evaluate ur students. Selectin based n: Cncerns f the teachers. Interest f the students. Labratry practices framewrk: Withut guidance General bjectives Cmpetitin Significant imprvements: Increasing f student invlvement. Reinfrcement f Engineering basics. Higher grade in students perfrming this activity.
