Servo Stall Currents PDF Print E-mail
Written by Evan Hollins   
Tuesday, 30 September 2014 17:23

A big rule change this year added the ability to use as big of a servo as possible while still staying under 5 amps per servo controller at stall. Unfortunately, many of the servos we commonly use didn't have documented stall currents. To find these, we contacted ServoCity™ and asked them what to do. They were able to talk to HiTec© and retrieve stall currents for many of the servos that they make. Here they are in a table shown below. 

We would like to thank ServoCity and HiTec for helping not just us but all of FTC!

We have just arrived in St. Louis, pulling up right in front of the NASA trailer! Wednesday is load in and judging, and Thursday, Friday, and Saturday are matches. Looking forward to seeing all of our friends from around the world and playing robots! We are in the Edison Division (will probably be listed as division 2 on the live stream page).

Live streams to all of the FTC events will be posted here.

Good luck to everyone competing this week!

Build a Better Bot Workshop with Patronum Bots PDF Print E-mail
Written by The Cougars   
Wednesday, 18 September 2013 08:33

On August 31st we got together with the Patronum Bots at their home base in East Troy, Wisconsin to put on our Build a Better Bot workshop. It was an all day event, and 12 teams attended, coming from Wisconsin and surrounding states. Throughout the day, we discussed topics such as game and robot analysis, mechanical and wiring practices, and static electricity. Along with topics about the robot, we also went over scouting and showed teams how we pick teams at tournaments. Near the end of the day, we held an “open work time” with several stations of hands-on activities. These included double drilling channel, creating static spray, switching from tamiya connections to anderson powerpoles, and making static detectors.

Check out the videos in the Build a Better Bot workshop playlist created by the Patronum Bots.

FIRST Tech Challenge
The official FTC Blog
  • The Game Design Committee is Accepting Applications!
    If you’ve ever been interested in participating in the FIRST Tech Challenge Game Design Committee, this is your chance! We will be accepting applications to add one member to the committee. The application will be open from 11/20/2017 through 12/18/2017 at 12:00pm EST.

    The current Game Design Committee is made up of five members, and we are looking to add a sixth member who will help the committee make progress on the 2018-2019 season game cycle. This individual will also shadow the current committee on a weekly conference call to get a feel for how the GDC supports the current season game.



    If you are interested, or know anyone interested, please feel free to pass this along! The official volunteer description, along with a link to the application are listed below.

    Game Design Committee – Volunteer Position Description
    The FIRST Tech Challenge is seeking an interested individual to serve one game cycle (approximately 18 months) as part of our Game Design Committee. The Game Design Committee is a group of volunteers who brainstorm, create, and implement all aspects of the FIRST Tech Challenge games (less production/fulfillment). As a member of the Committee, this person will be responsible for attending weekly conference calls, and providing input and creative ideas for the game currently being designed for next the season. This person will contribute to the creation of Game Manuals Part 1 and 2, and to other supporting documents needed for the game. The person in this role will provide support for the game once it is released for the current season via the Official Q&A forum. We are looking for someone who is creative, is a team player, and can meet the time commitments outlined in the job description.

    Job Description:
    • Contribute a minimum of 5 hours each week, including a weekly conference call that occurs during normal business hours (eastern time).
    • Provides input during the design phase to insure the game meets requirements outlined by FIRST.
    • Contribute to the design phase to make sure game elements meet quality standards and budget requirements.
    • Contributes to documentation and manuals needed to support the game throughout the season.
    • Provides support through the Official Q&A Forum to answer team related questions throughout the season.
    • Maintains confidentiality of all aspects of design process. 
    • Applicants must be a minimum of 25 years old.
    • Position may require a trip to FIRST Headquarters in Manchester, NH.
    • CAD experience is a plus, but not required.
