Science Olympiad Robots
by olin4 0 Comments favorite 3 Viewed Download 0 Times

Okay, so what is a robot? Per definition of en.wikipedia.org, the Holder of All Human Knowledge, a robot is: a mechanical device that can perform physical tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a pre-programmed computer. In the context of Science Olympiad and other small engineering competitions, we are looking at the first type, human control. There are plenty of opportunities to put autonomous features into a Science Olympiad robot, but if you are reading this for content, it is likely beyond your scope and unnecessary. Therefore, for the purposes of this text only, a robot will be defined as: A mechanical device, operated under the direct control of a human, that is engineered to perform a specific task or accomplish a goal. In this case, the goal is to compete in Science Olympiad's Robot Ramble event. And win. More on that later. I'm not smart enough to build a robot! Yes you are. Modern technology has developed to the point at which it permeates our lives. One side effect of this is that it is much easier to learn and try out than in years past. The hobby robotics market is only increasing, and there are a number of companies that specifically make products catered to robots and their builders. Full directions and kits are available to build or program small robots. In some cases, they're even premade, and all you have to do is mess with them. This is often the best way to go about learning.

Very old Ricoh camera and lenses to work with newer DSLR ... - Rqna

Asked by SixfootJames on 2012-10-24T11:49:33-04:00 I've been given an old bag of Ricoh camera and lenses and I find that it would be such a waste not to be able to use in some way all this again for something. Can you give me some suggestions as to how to use this kind of equipment with a newer camera like a Canon 600D? Archives Arts Questions and Answers Photography Questions and Answers Oct 24th, 2012 Archives Week 43, 2012 Archives October, 2012 Archives Tags Lens Dslr Old Lenses Best Answer Answered by John Cavan on 2012-10-24T23:11:20-04:00 Ricoh, historically, used the Pentax K-mount for their film SLR cameras, but with a slight and important modification: they added a pin that's used to indicate the aperture is in auto mode for shutter priority use. With some careful work, you can http://forums.dpreview.com/forums/post/25959708 for use on K-mount bodies made by Pentax or Samsung or with a http://rads.stackoverflow.com/amzn/click/B003Y3EJMU for Canon EOS digital and film variants. Nevertheless, if you have Ricoh K-mount lenses, that pin has to go. You can confirm if you have these based on this helpful bit of info from Wikipedia: The R-K mount is used on Rikenon P lenses, Ricoh bodies that include the letter 'P' in their model number, and some non-Ricoh lenses. Now, it's also possible that the Ricoh lenses are M42 screw-mount lenses also known, funny enough, as the Pentax mount when most film cameras had it and Pentax was the SLR king. If that is the case, and it's easy to tell by just looking for threads on the lens mount, then you can easily get...

Analyzing Design Tradeoffs in Large-scale Socio ... - Christoph Dorn

Emerging online collaboration platforms such as Wikipedia, Twitter, or Facebook provide the foundation for socio-technical systems where humans have become both content consumer and provider. Existing software engineering tools and techniques support the system engineer in designing and assessing the technical infrastructure. Little research, however, addresses the engineer’s need for understanding the overall socio-technical system behavior. The effect of fundamental design decisions becomes quickly unpredictable as multiple collaboration patterns become integrated into a single system. We propose the simulation of human and software elements at the collaboration level. We aim for detecting and evaluating undesirable system behavior such as users experiencing repeated update conflicts or software components becoming overloaded. To this end, this paper contributes (i) a language and (ii) methodology for specifying and simulating large-scale collaboration structures, (iii) example individual and aggregated pattern simulations, and (iv) evaluation of the overall approach. Keywords: Design Tools and Techniques, System Simulation, Collaboration Patterns, Large-scale Socio-Technical Systems

October 2013 issue - Doherty High School

Did you miss your chance to join newspaper, or do you just want to be a published writer? Send stories and contact info. to dohertyspectrum@ gmail.com for a chance to be publish in next month’s issue! T he fourth amendment of the constitution states, “The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” So why is the government trying to put both the SOPA and PIPA laws into effect? SOPA stands for Stop Online Piracy Act, which simply means if it is passed it will allow the internet to be censored, meaning any copyrighted material and any sites giving off illegal music/movies, will be terminated and “censored”. PIPA which stands for Protect Internet Protocol Act would be able to give the US government and copyright holders’ additional tools to curb access to rouge websites dedicated to infringing or counterfeiting goods. PIPA works in hand with SOPA. In 2012, these laws came into question, but the people fought to make sure it did not happen. The issue is being brought up once again. The part that is irritating to people is that the government is trying to pass these laws right under our noses. The website Wikipedia went on a “blackout” protest which shut down the website for a day. A part of the law says that: “Streaming a copy- righted work over the Internet is considered a violation of the public performance right.” This says that if a cover song and/or remake is made and if it is under a copyright, the person that made that cover or remake can be criminally charged with a misdemeanor. People have become famous from doing covers such as Ariana Grande, Justin Bieber, and many more, but imagine it being against the law to do these covers or remakes. Imagine the talent and musical masterpieces that would be missed. Celebrities such as comedian Aziz Ansari, and Trent Reznor of Nine Inch Nails are against the SOPA and PIPA acts.

iOS is the name (as of version 4.0) of Apple’s platform for mobile applications The iPhone was released in the summer of 2007 According to Wikipedia, it has been updated 30 times since then, with the 31st update slated to occur when version 4.3 is released soon (currently in beta) iOS apps can be developed for iPhone, iPod Touch and iPad; iOS is used to run Apple TV but apps are not currently supported for that program © Kenneth M.
