  1. Facilitating Active Learning with Inexpensive Mobile Robots Stephen Paul Linder Brian Edward Nestrick Symen Mulders Catherine Lavelle SUNY Plattsburgh

  2. Goals • Improve student learning throughout the computer science curriculum • Improve student retention rates • Promote good problem solving skills, including skills in • synthesis of relevant information, • design of viable solutions using partial information, and • implementing designs SUNY Plattsburgh

  3. Approach • Use of simple wheeled robots as a software platform SUNY Plattsburgh

  4. Rationale From Magnesen, 1983 SUNY Plattsburgh

  5. Why a Car? • Stable mechanical base • Easily understood by anyone who has ever driven a car • Provides exposure to embedded and real-time software SUNY Plattsburgh

  6. Pedagogy • Active learning • The ability to learn through interaction with one’s environment. Examples are • Team projects • Lab classes • Collaboration with faculty • Constructivist Learning requires • the construction individual models of knowledge • a manipulation space which reflects the effects of the student’s actions • Real machines rather than simulation SUNY Plattsburgh

  7. Robot Overview SUNY Plattsburgh

  8. Parts List Total Cost: $602 SUNY Plattsburgh

  9. Example Projects SUNY Plattsburgh

  10. Locate and Find a Beacon • Locate beacon and then traverse obstacles to beacon. • Beacon • Infrared source modulated at 38 kHz • Detector • Sharp IS1U60 TV remote control sensor • Obstacles • “Short” 2x4 studs on edge • “Tall” copier paper boxes SUNY Plattsburgh

  11. Active Steering of a Tractor Trailer • Can a trailer automatically steer its back wheels so that the turning radius is reduced? Remember to show videos SUNY Plattsburgh

  12. Maze Mapping • Using a robot under control of a PC to automatically generate maps of simple mazes, e.g. Remember to show videos SUNY Plattsburgh

  13. Website • Website contains • Parts and price list • Mechanical and electrical assembly instruction • Software Library • Find link at http://faculty.plattsburgh.edu/stephen.linder/ Academic/ProgrammingProject/index.html SUNY Plattsburgh

  14. Conclusion • The Handy Car has provided a valuable facilitator of active learning at SUNY Plattsburgh. • Future work • Upgrade processor board to HC12 to facilitate faster communications to Handy Car. • Finalize software to share one Handy Car among multiple students using a client/server architecture.
