  1. Chris Odom www.basicxandrobotics.com chris_odom@georgeschool.org George School, Newtown, PA Welcome to the1st Interactive Science and Technology Open Houseat George School!

  2. Session I • Introductions with personal/professional backgrounds • A plea for interactivity – too much material to cover • A Brief History of Computer Science at GS • The Evolution of Robotics Education at GS • What We Do Now • A Roundtable Discussion • Success stories • What’s possible with robotics education • The Future

  3. A Brief History of CS at GS • The skill-level of the GS student • Desktop programming: Database applications • Desktop programming: Student driven applications • Kylan Turner, Brian Patton, Max, and ESRA • The birth of robotics at GS and the need for a textbook • Aim: Have fun with solid math and science education • Taking math and science for granted

  4. Evolution of RoboticsEducation at GS • The bumps and bruises of the early years • The transition from teacher-centered to student-centered • The role of the teacher, student, textbook, website • How to skip around • Challenge Problems • The benefits of peer instruction • The role of competitions and collaborations • From technical to creative: building on simple tasks • The cost: Individual purchases vs Classroom Packs

  5. A Self-paced Curriculum

  6. The BX-24 microcontroller • The BX-24 is a 24-pin microcontroller made by NetMedia • Small and Fast • Floating-point math • 16 I/O pins (8 built-in A-to-D converters) • EEPROM storage • About $45 • Programmed with BasicX, a high-level language compatible with Visual Basic. BasicX is free.

  7. Exciting Technology The BX-24 can be used to: • Autonomously control nearly any mechanical device such as robots, vehicles, airplanes, vacuum cleaners, etc. • Output electrical signals to (thereby controlling) motors, speakers, LCD panels, lights, LEDs, etc. • Read data such as temperature, light intensity, magnetic field strength, force, distance, flame (IR), conductivity, etc. • Record data in space, underwater, your back yard

  8. Personal Computer vs BX-24 The PC: • Is faster • Has more computing power • Is larger, heavier and therefore more stationary • Is more expensive • Is dependent on AC power • Is better suited for gaming and desktop programming

  9. Why BX-24? The BX24: • Is smaller and therefore transportable • Is cheaper • Has no moving parts: data a programs are burned in to the chip. Can be removed from power • Runs on a 9V battery • Is better suited for remote and mobile applications • Students love it!

  10. Creating a Program • The program is written on the PC in the BasicX language • BasicX can be downloaded for free at www.basicx.com • The code is saved as a simple text file. (New programs start with a blank page.) • When the program is ready to run, simply press one button to compile the program into a language the BX-24 can understand • The compiled program is sent to the BX-24 via a serial cable

  11. The Robodyssey Motherboard • Robodyssey Systems in Trenton, NJ designed and sells the RAMB • Makes programming the BX-24 easy • About $45 • Could do it yourself but why?

  12. Walking Robots Wheeled Robots (My students use the Mouse) Expressive Robots (ESRA) Kits

  13. Just Toys? • Fun, but not a toy • Learn a real computer language • Learn logic skills • Learn electronics • Research universities are now using the BX-24 to teach computer science • Microcontrollers allow the average person to do what only NASA could do just a few years ago • Springboards into other “serious” fields such as electronics, aerospace engineering, manufacturing, automotive and medical applications, etc.

  14. BasicX and Robotics • Textbook written for novices and beginners ages 12 and up (especially for high school and college) • Only one of its kind • A teacher by your side to walk you through material • Over 300 problems and 400 full color images. 365 pages. • A complete and rich curriculum • $44.95 textbook • Who has it?

  15. Retail $499 (20GB), $599 (60 GB) http://www.us.playstation.com/News/Editorials/38

  16. Tori’s Morse Code Brute force vs. elegance Robot Dance Art in motion Line Following Mouse Not dead-reckoning but not so smart Follow Me A bit smarter, but still constrained Obstacle Avoidance/Tabletop Rover Human & robot intelligence are required Clean Sweep with Live Video! Smart and useful (sort-of) Thor: Firefighting Robot Smart and useful (sort-of) ESRA Expressive robot Used in psychological research labs across the country including Yale Autistic research in high school? The Roach A walking robot RoboSapien Hack Brain surgery The E-Bot and Crawler H-bridge technology RC Toys and Car Hack H-bridge technology Robot Soccer Junior 2050 Challenge Mini Grand Challenge 2015 Congressional Mandate Robots in Action Let’s take a look at a few robots controlled by the BX-24.

  17. Relays The itty-bitty BX-24 can control household appliances Spirit II The BX-24 takes GS payload into space Environment Sensing Station Inexpensive, robust, remote in situ data collecting Helium Balloon Payload Another in situ scientific platform Scientific and Other BX-24 Apps Robotics isn’t all that the BX-24 can do. Take a look:

  18. It can be rocket science! In 2003, NASA, Penn State, and Clemson University launched a Terrier-Orion rocket from Wallops Island, Virginia. The rocket, part of the SPIRT II campaign, was in space for about 10 minutes and experienced nearly 20-G’s during liftoff.

  19. SPIRIT II Payload • George School physics and robotics students designed an experiment that flew onboard that rocket. • A BX-24 and RAMB motherboard were used to measure the forces of liftoff and any changes in temperature within the payload. • The experiment cost less than $100 (the force sensors cost 4¢ each) and returned excellent data.
