I have been designing a custom two speed gearbox, and I have a question regarding the dimensions of the bimba cylinders.

What is the total length of this bimba cylinder while fully retracted? Fully extended?
http://www.andymark.com/product-p/am-0292.htm


What exactly is the difference between these two bimba cylinders?
http://www.andymark.com/product-p/am-0292.htm
http://www.andymark.com/product-p/am-0591.htm

Does the latter maintain an extended position when no air is pumped into the cylinder? If so, can the spring-style cylinder be used as a fail safe, in the event that the pneumatic system ruptures or the robot is undergoing a stall load situation?

Ben here, from Enable. You may remember me from some FRCMastery.com LabVIEW training videos called the “Tip Jar” which our company did for previous seasons.

For this past season, we worked with FIRST to provide the interactive FRC Game Manual, and the iOS app. We also partnered with App Delegates to provide an Android App.

We’re planning our improvements for next season, and would love your feedback.

At any other competition it would be, but with such a deep field, you might be able to take the gamble and pay off big. Any predictions on super alliances yet? I'm feeling 1114+469+2826+someone as the champs. After a strong performance on Archimedes, 1114 was plagued by bad luck on Einstein and walked away with a single gold (But kept an eye on the big prize) and are itching for redemption. As their first pick, their old friends 469 will be more than willing to bring their super sonic shooter to the courts. 2826, after falling to 1114 in three intense matches on Archimedes, will prove to be the decisive third pick. They're good, but with such a deep field, may fall short on the seeding.

Gotta stay faithful to the team I love.
But to keep the other thread less cluttered, here's an open thread for your thoughts.
By all means, contradict me and prove me wrong.

Here is an e-mail I just got from FIRST
Dear FRC Teams,

Please allow me to update you on our examination of the Championship final rounds.

As part of the examination, FIRST will evaluate the field and all robots that were on Einstein as a complete system—a system as comparable as possible to what existed at Championship. We have received and reassembled the Einstein field equipment at headquarters in Manchester, and we are in the process of retesting its functionality. In addition, we are asking each of the twelve teams that competed on Einstein to (1) allow FIRST to ship their robot to Manchester, (2) provide an adult representative to be present for testing, and (3) provide detailed systems information, including driver station logs and robot code. Each of the teams has acted with the utmost grace and professionalism, and for that we are truly grateful.

We also recognize that many of you have important information to share about your experiences this year. Thank you to those who have passed along such information in response to my April 29th e-mail. To make that process easier, we have set up an e-mail for you to share your experiences and expertise: 2012FRCfeedback@usfirst.org. Please know that while all of your feedback will be reviewed and considered, FIRST will not be able to respond to every e-mail.

We are also investigating the issues on Einstein with independent, outside experts as well as respected leaders in the FIRST community. We remain steadfastly committed to understanding the root causes of the issues and resolving them. I will continue to report our process, progress and eventually the findings of the examination.

Sincerely,

Jon ]]> General Forum Bruceb http://www.chiefdelphi.com/forums/showthread.php?t=106482 The physics of pushing http://www.chiefdelphi.com/forums/showthread.php?t=106481&goto=newpost Tue, 15 May 2012 18:39:35 GMT I'm trying to decide on a good gear ratio for our drive system, but I'm kind of stuck on one thing - I can't figure out how to calculate the force the robot could inflict on another robot while pushing (not momentarily).
