Design Questions

Battery and Power


Q: Can we use a device that can plug into the wall?

A: No, it's not safe! Please adhere to the rules and consider safety at all times.

Q: Can we use gel batteries like the ones that are used in wheelchairs?

A: NO. Gel batteries are a form of lead acid batteries, which are not allowed.

Control Systems and Autonomy


Q: Can we touch our device once the three minute time begins?

A: The team is allowed to touch wires, strings or other items that are used to control the device, but you cannot push it. The device needs to do the work!

Q: Can we use a remote control?

A: If your device requires some type of external control, you may use any control system you like. Remember that there is likely to be interference if you choose a wireless approach.

Materials and Supplies


Q: What kinds of supplies are useful to have around?

A: Hot glue guns, safety goggles, nylon ties, PVC pipe and a PVC pipe cutter, superglue - things that are easy to cut, shape, and put together are excellent for prototyping.

Miscellaneous


Q: Do you have any sites that would be helpful for mechanical instruction, like gears?

A: www.howstuffworks.com and the How Things Work book are two great resources.

Proposed Designs


Q: Can the solution separate into multiple pieces after time starts?

A: Yes, and your solution could start as multiple pieces.

Q: Can we use a remote controlled airplane kit for our solution?

A: If that helps you complete the challenge, sure, but your own design will be more impressive to the judges. Airplane kits tend to be expensive; you might want to challenge your team to come up with a low-cost solution that relies more on your own ingenuity. If you DO choose to create your solution using a kit, keep in mind it must be small, as there will be up to five satellites and demonstrations going on at any given time on Event Day. AND ­VERY IMPORTANT ­ if you use a plane kit, you will need to prove that you have made modifications to it to customize it to meet the Challenge, so documentation will be especially important.

Q: Can I have more than one solution?

A: No. However, your solution may be comprised of more than one device.
