|GEAR - Geauga Engineering and Robotics|
GEAR Wins Seven Awards at 2017 National Robotics Challenge!
All GEAR projects involving electricity employ voltages below 20 volts. This policy eliminates the dangers of working with higher voltages. While many electronic devices are powered from low voltage sources (e.g. batteries), many others are powered by higher voltage AC sources (e.g., 120 volts) supplied in the home via electrical outlets. As our members become proficient in electronics work, they may desire to take on repair work or projects that employ higher voltages for power. While this type of work will not be done as part of the GEAR curriculum, our advisors would like to offer some information for you to consider as parents and club members. Please review the information provided in the link below before proceeding with any work involving voltages higher than 20 volts.
The curriculum is now divided into a page for each of our groups:
NRC Rescue Robot contest
The Art and Science of Selecting Robot Motors
Learning to use computer-aided design (CAD) software
Members wishing to use the new club 3-D printer for GEAR projects will need to learn how to use CAD software. Use the link below to get started learning CAD.
GEAR Astronomy Curriculum
GEAR Club is not just about robotics. We explore other areas of science and engineering. Here are some projects for members who are interested in astronomy. Some of the dates mentioned in the papers below have past. In order to plan your observations, you will need to know when and where Jupiter, the Moon and Venus are in the night sky. Sky and Telescope magazine has very useful information on planet positions: http://www.skyandtelescope.com/observing/ On this page select the "this week's sky at a glance" item for the current week. For a more general list of planet visibility over the years, try this web site: http://www.nakedeyeplanets.com/visibility.htm
Notes on Geologic history of the Moon -- use this as a reference for your Moon project.
Mars - while we don't have a formal lesson plan for Mars, here is some information you might find useful in designing a Mars project.
Here is a photo of Mars that I took on May 30, 2016. The camera exposure was 10 seconds at f 4.5. Mars is the bright object in the upper right of the photo. If you have a camera that can take long exposures, try using it to record the position of Mars on different nights. I also took photos on May 23 and May 27 and have marked the position of Mars on this photo using red arrows. During this time period Mars is in retrograde motion (east to west).
This is a full frame of the Mars photo taken on May 30. I have labeled Mars, Saturn and the Red giant star Antares. I have also drawn in with red lines the constellation of Scorpius.
La Favre Observatory
GEAR Club members interested in astronomy are welcome to visit the La Favre observatory and use the 14 inch telescope. The robotic mount for the telescope has been repaired and the observatory is now operational. If you would like to watch the robotic mount go through its paces, watch this video.
