Hi people, sorry for the super late notice

If you're doing the retractable wind turbine, then you need to do some research on which of the four retractions methods discussed would be the best. Take into account the following:

• How big/heavy should the retractable turbine be?
• What kind of turbine will be used?
• How durable are each of the designs?
• Which ones can we make by the competition?
• Which can lift up/down using the least power?

Here are some places worth looking at:

By Sunday, you should have your choice for which design you think is best. You should do research on it and understand how it works. You need to have a drawing of the entire collapsible wind turbine and how it will function. Also do some research on what material you think it should be made of.

Hi guys,
If you are a part of the blade design group, you will need to bring to the meeting one new blade design. Of your design, you will need to follow these directions:

1. Draw a 8 inch diameter circle (4 inch radius) on a sheet of paper using a compass (圆规)
2. from the center of the circle, draw two perpendicular lines running through the center
3. You should now have four congruent quarter circles

4. Trace out your design on one quarter circle (you only need one paper trace-out)
5. find some cardboard
6. use the paper trace-out to cut out 4 of the same blade designs
7. Bring the blades to the meeting to test them
Your blades should only be at most 4 inches in length
Please bring 4 blades. This is so we can change the number of blades that are being tested.

Here are some questions to get you started:
What is the shape of your blade?
Is the majority of the mass in your blade at the tip or in the center?
Is the blade itself large or small?
You can turn these knobs and see what happens to the energy conversion during the meeting.

Parents: If your child needs help setting the drawing the quarter circle or cutting the cardboard, you should help them. But please allow your children to design their blades themselves.

Evening Robot Group Agenda (9/7)

Jeremy
- Dropping the Shipment Payload for Mission 1
- Build a fork for Tube Module
Jon Jon
- C-Shape baskets for satellite orbits
- Strengthen Food Production Attachment
Sophia
- Build a basket for the 3-D printing red brick, bring the brick back to base
- Build weight for  Crater Crossing Mission
Zoey
- Drop Mineral Sample for 3-D printing mission
