Transcontinental Express

May 31st, 2013 | Posted by admin in Education | Fun! | Ideas | Inspiration | Michigan | New York | RaspberryPi - (Comments Off on Transcontinental Express)

Recently I found myself with a couple months of time off. I decided to use it in the most productive manner I could think of so I booked a one month rail pass on Amtrak. I already had plans to go to Ada Camp in San Francisco and my sister’s high school graduation in Mechanicsville, Virginia. At $670 the rail pass was cheaper than plane tickets and I got to see most of the country. Tentatively I plan to visit Portland, San Francisco/Silicon Valley/Oakland, Iowa City, Richmond Virginia, and New York City. I was able to schedule my trip so I could take the Empire Builder line, the California Zephyr, and a good chunk of the Coast Starlight. My tentative schedule is below.

My exact schedule for the first leg of the trip can be found here. Packing for this trip has been a little crazy. I want to squeeze everything I need into a back pack, but train travel is tough as traveling in coach requires that you bring a lot of necessities (and entertainment).

Try squeezing a month's worth of clothes, electronics, supplies, and food into a backpack!

I purchased a Nexus 7 tablet for the journey and I have a tupperware container with a raspberry pi, arduino, makey-makey, breadboard, and various component to keep me entertained on the train. The transcontinental trips are almost three whole days so I should have lots of time to read, code, and build cool stuff with my fellow travelers. Hopefully I will post some cool stuff from the road, and have 4G coverage for most of the trip.

My home for the next month.

FIRST 2013 Robot Ideas

I am helping mentor with FIRST Robotics Team 830 this year. Here are the rules for the  2013 FIRST Robotics Competition.  The TL;DR is that the robot basically needs to collect and shoot frisbees and climbing a really tall tower. The video below describes things very succinctly.

 

 

We need to get this done in the mater of just a few weeks. I started looking for a few inspiration ideas.

 

A personal favorite, the RiSE robot from the KodLab. A little too complex for our timeframe.

 

 

I really like this mechanism but I am not sure it will work on the pyramid.

 

 

Here is a slightly simpler version of the same mechanism.

 

 

This is a similar approach. Not quite applicable to our situation.

 

 

Here is a FIRST team actually meeting the challenge.

 

 

This design looks like it could be used for our applications with some modifications.

 

 

On the subject the frisbee launching this mechanism rules.

Finally, a nice primer on the physics of frisbee launching.
