A quick answer to your question is no you have to create your own from the parts. More in depth answer for the reason behind this is that in order. To create a fair competition BEST has given everybody the same parts and those parts are the only thing that you can use. This way money is not an issue for teams sense the kit of parts is provided for free. If you would like to view the compleate rules go and get the rules from the BEST File Maneger located at the password to get into it is located on the last page of the notebook you got from your hub on kickoff.

Taken From 2014 Awards and Judging Policies Part I

Exhibit and Interview Guidelines

   Check with local hub for standard table size.  At regional championships, each team will be provided with a standard six-foot long table (approximately 29 inches wide) upon request.

   Check with local hub for maximum allowed floor space for exhibits. An 8 X 8 X 8 exhibit space will be allocated per team at the regional championships.

   Skirting for the table will not be provided.

   Each team should bring one extension cord and one power strip. Check with local hub for possible electricity and electrical limitations.

   Other exhibit items may be used, but must not exceed the space allocated by the hub.

   Teams are encouraged to avoid using expensive store-bought display boards and structures and opt for more creative and hand-made exhibit props.

   Any audio-visual equipment needs and extra extension cords will be the responsibility of the team.

   Each team is responsible for security of its own material.

   Each team is also responsible for breakdown of its team materials and clean-up of its exhibit area following the awards ceremony on Game Day.

   All material should be clearly marked with the appropriate identification and contact information.

   Check with the local hub concerning when and where team exhibits can be set up.

   As a general rules, candy and other food and drink items are not permitted at exhibits as complimentary handouts. Check with local hub or regional championship policies concerning this rule.

   During the designated interview time, at least one student representative from the team must be present who is able to respond to informal questions asked about the exhibit. In addition, student representatives should be aware that judges may ask questions concerning robot design and construction.  These questions will be part of the interview evaluation of the team.

   Teams should expect to be visited by three to four different judges during this period.

   Judges may also interview team members in the pit area and in the seating area.

Please reply to this topic with any comments, issues, or changes that you have about Linkage. Any feedback is greatly appreciated. Thanks.

In 2013 since there were two degrees of freedom in our arm and three degrees of freedom in the claw, controlling the robot required careful integration of software and hardware. To facilitate this, we attached potentiometers to each of the arm joints. We attempted to write a program that used the values from these potentiometers to calculate the angle of the arm based on trigonometric relationships. Using the calculated angle, the program would be able set the servo angles so that the claw remained level at all times.

While this seamed like a great idea at the beginning of the season we quickly learned that it would be one of the most complicated parts on the robot. The first issue we found was when we were figuring out how to transfer the rotation from the arm joints to the potentiometers, this is what eventually led to the failure of the code. We then had to figure out how to calculate the angle to move the servos to which involved trigonometry identities. But once we had the code working we figured out that the way we connected the potentiometers to the arm joint, by rubber covered wheels, was slipping making all of the values wrong. By the time we figured this out it was too late in the competition to redesign it so we ended up scraping the idea.

Attached at the bottom of the file shows the calculations we made in order to get the code working. We hope your able to learn from it.

What do you guys think of the 2014 game teaser? What kind of game do you think it will be? Obviously it is about windmills but the actual gameplay could be anything.
