25High Level Details Lessons___________________________Lukas- Discussion of our take-aways of the project25Future WorkMultifunctional variable resistance unitRealistic motion frequencies (i.e. gravel or pavement textures)Improve gravity compensation systemHydraulic platform for lifting mechanismRealistic bike terrain mapsGoogle street view interfacingAudible noise reduction

26High Level Details Future Work___________________________Lukas- How we see the ideal project26Excerpts from our MinutesOct 1: Robot skyscraper window washerJan 11: Side to side tilting not really possibleFeb 20: Reed switch, serial Read/Write done de-bouncing doneApril 6: Videos!!!27Conclusion___________________________Transition back to MikeThank audience for time and interestKey takeaways for us27Acknowledgments Lucky One (electronics advice)Fred Heep (electronics advice)Professor Bernhard Riecke (VR advice)Gianmarco Spiga (Arduino and pie)Martin Berryman (metalwork assistance)Brian and Physics Department (machine shop assistance)Yeelen Merhi (mechanical design inspiration)Rest of the Hewitt House (Audrey-Anne, Pier Alexandre, Sean Edmond)ESSS (for ESSEF funding grant allocation and distribution)28Acknowledgements___________________________Mike28Questions?29Questions
