SENSORSCITY (Science and Engineering NASA Site of Remote Sensing - City) provides educational resources for K-12 students, parents, and teachers related to remote sensing, robotics, and earth and space science. SENSORSCITY can be programmed by RoboLab programs from the classroom or with programs already on the site. Data-logging can be done over the Internet from SENSORSCITY. Data logging can be done to get ideas of light sensor readings along lines and other colored areas, rotation sensor numbers to various missions, times until touch, etc. Data gathering and graphing can be done easily in PROGRAMMER without going into INVESTIGATOR.

Http://netapps.marshall.edu/lego has links to the LEGO City housed at Nick J. Rahall, II Appalachian Transportation Institute.� It is a NASA remote sensing� site � SENSORSCITY, and a� Red Rover site and Mars Station. LEGO City is a high-tech city model complete with roads, bridges, and traffic incorporating intelligent transportation systems, such as sensors to control and monitor traffic. This site is available to K-12 classroom teachers to have as a hands on learning module for their students to learn abstract math and science concepts. At the college-level, the city is be used in teacher training. Programs like the LEGO 24-Hour City at RTI use hands-on, real-life activities that build interest in engineering, robotics, and remote sensing among young people. This interest may well stay with the students throughout their education, and lead them to careers in transportation and traffic fields. Remote sensing is becoming increasingly useful in real-life traffic situations.� An example would be pre-paid passes that enable vehicles to pass through interstate toll areas without stopping.� Use of such technology helps commuters to plan better routes, and improves traffic flow.

Any where you are on the Internet, there is a live camera view of the Nick J Rahall, II Appalachian Transportation Institute LEGO City on http://legocamera.marshall.edu

http://lego.marshall.edu requires no plug-ins or downloads.� This web version has the advantage of ease so many more people have connected to Marshall in the last year.� During the first months the real rovers were on Mars there were often the full capacity of 60 people per hour. There are also instructions to use the Red Rover as a GUI on the Instruction page of SENSORSCTIY.

Thanks to my first K-12 grant from WV Space Grant Consortium, Davis Creek Elementary was enabled to have the Red Rover project.� To bring the Red Rover into the Davis Creek 5th�grade classroom a parent constructed a Mars Red Rover box with the clear Plexiglas bottom so the class can see all the action.� Drivers can also see into the classroom and even the student operating the computer that commands the rover. The GUI version was used by students from Australia even before Davis Creek was set up with a Mars Station Web Red Rover.

I brought the RED ROVER display to run at� MindFest at MIT in 1999.

RoboLab programming is through http://SENSORSCITY.marshall.edu Live camera view of LEGO City is at http://legocamera.marshall.edu Teleoperate through Red Rover at http://netapps.marshall.edu/lego The city uses RoboLab, LabView software, to enable students at a remote site to drive the vehicles over the Internet.�

When working out programs ideas early in a new FLL season it is nice to get ideas of light sensor readings along lines and other colored areas, rotation sensor numbers to various missions, times until touch, etc. Data gathering and graphing can be done easily in PROGRAMMER without going into INVESTIGATOR. Data-logging can be done over the Internet to SENSORSCITY and data received back anywhere. That data-logging program can be used as a template. Those of you with laptops with RoboLab can have immediate practice in data-logging.� I will give instruction on how, even after FLL season is over, RoboLab can be used over the Internet for data-logging from SENSORSCITY. http://netapps.marshall.edu/lego

Example programs to run can be saved to your computer and used to send to SENSORSCITY. They can also be used as template to make programs for you.

Write a new program and drop in the data logging icons from the example program to use from SENSORSCITY.

Highlight the data-logging icons in the example program to use from SENSORSCITY and drag to your program. Then wire them in by holding the mouse on the next icon and tapping the space bar.

To be able to use data logging icons change to Computer Tools 5� by clicking the wrench in the upper left hand corner of the Change Inventor Level drop down window from Projects.

The program to Upload Data is in GPrograms.llb found on the RoboLab directory ������������������������������� VI.LIB

Write a new program and drop in the data logging icons, run the program and� "see" the needed information. This graph shows that the robot crossed the yellow line twice two seconds apart� and the rotation sensor went through 68 sixteenths of a rotation before the first touch.

Now is the time to do some data-logging.

Stop by the LEGO City at Marshall University often.� Usually the traffic that goes through the photo gate is a little car.� At various times of year the car might be replaced by a turkey or reindeer.� There are different themes and different challenges to take each month.

LEGO camps and workshops can use the SENSORSCITY Internet activities to add teleoperation and remote sensing to their hands-on activates. Teleoperater licenses are awarded to people that do remote sensing. Ideally students have the hands-on opportunity to build a transportation project at school.� They try out the programming and data logging.� Then they can send their programs on to SENSORSCITY.� Three colored lines on the graph are from the sensor readings from three sensors at the LEGO City.� The one at the top is the light sensor reading as the traffic goes through the photo gate.� See the dips each time a car passes.� The green graph line is the light sensor reading as different colors move in front of the third sensor.� The red step line is the touch counter on the Monorail stations. SENSORSCITY can be programmed by RoboLab programs from the classroom or with programs already on the site. Also, camps in other states have used the http://SENSORSCITY.marshall.edu resource.

The Nick J. Rahall, II Appalachian Transportation Institute (RTI)� LEGO 24-Hour City is a Science and Engineering NASA Site of Remote Sensing (SENSORS).� With the use of tele-robotics and LEGO RCX robots, students can explore and discover different environments. RTI is located at Marshall University in Huntington, West Virginia. One of the goals of the RTI is to provide quality transportation-related programs to elementary, middle, and high school students, with the express purpose of attracting students to careers in transportation fields. Each year, a variety of workshops are sponsored which enable students to explore the technologies and issues related to transportation in the United States.
Linda Hamilton, mathematics instructor at Marshall University, working with Chris Rogers of Tufts University Center for Engineering Educational Outreach, has designed the LEGO 24-Hour City at RTI to be operational for remote sensing.� Many schools have remotely operated the City�s monorail, gates, traffic counters, and vehicles.
