FIRST Tech Challenge Tech Talk: Technology Evolution

FIRST� is proud to introduce the REV Robotics Expansion Hub as an exciting addition to our
FIRST� Tech Challenge kit for the 2017-2018 season. This new drop-in device replaces the functions of five Modern Robotics devices. The REV Robotics Expansion Hub accomplishes this by including:

  • Four DC motor outputs with matching encoder ports
  • Six servo motor outputs
  • Four analog sensor inputs
  • Eight digital sensor inputs
  • Four independent I2C sensor buses
  • Built-in inertial measurement unit (Bosch BNO055 9-axis absolute orientation sensor)

Teams will continue to program their robots using the same languages they do now--running on the
Android operating system. Android handsets will also continue to be the interface at both the driver
station and on the robot. Teams may use up to two REV Robotics Expansion Hubs on their robots.



REV Robotics Expansion Hub Benefits:

  • Space-saving size
  • Reduced complexity of wiring
  • Reduction in cost
  • Uses more compact and robust connectors





Both the REV Robotics Expansion Hub and Modern Robotics configurations are legal for use in the
2017-2018 season. Robots will have the same capabilities with either product. For the 2017-2018
season, FIRST will only offer the REV Robotics Expansion Hub in the FIRST storefront. Teams using Modern Robotics electronic devices may purchase additional electronic devices directly through Modern Robotics.

AndyMark Will Now be the Source for New FTC Fields and Game Elements

FIRST Tech Challenge is excited to partner with AndyMark on Field and Game Elements for the 2014-2015 Season.  That means you no longer have to build a practice field, but can purchase one from AndyMark and have it shipped to you after Kickoff (no Team pre-orders!). They will offer teams a full or half field option and each kit comes with the Field Setup elements and Game Elements. Don't worry, you can still build a field if you want to! But what will they be? Each year, the Game Design Committee drums up a new element that presents a variety of manipulation challenges for teams to overcome. They've chosen wiffle balls, rings, two varieties of racquet balls, hockey pucks and batons, to name a few.  Since elements are different from year to year, teams must redesign their robots each season to accommodate the new item and the scoring objectives. What do you think this year's element will be?  Leave your guesses below and go to a kickoff event , or go to www.usfirst.org/...
