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
  • FIRST Stars in The Fosters!
    Have you been watching The Fosters on FreeForm *? The FIRST® community has a starring role this summer with both FIRST® Tech Challenge and FIRST® Robotics Competition robots featured prominently in a STEAM-centered story line in an upcoming episode. But we don’t want to spoil anything.



    Why watch alone when you can throw a viewing party with your team? Here are 7 ideas for an awesome #omgrobots-themed viewing party for the episode airing August 15th at 8/7c on FreeForm.

    1. #makeitloud. Of course you want to bring your besties from your team, but look beyond the usual suspects to involve some new folks so they can get a taste of how amazingly fun FIRST can be. We bet your team has some great graphic design talent. Whether you go steampunk or ‘50s sci-fi, make sure your invitations reflect the main STEAM-y theme.

    2. Gather plenty of chairs and/or cushions. There will be plenty of time to crouch in those crazy robot-building poses when your FIRST season starts. For now, get comfortable.

    3. Get your decorations on point. From the moment they see your cool robot wreath to the gear garlands you have hung on the wall, your guests will have no doubt what the party is about. Blow up some balloons in the FIRST program colors to show your FIRST pride. You could even make a robot cupcake stand. (But then you will probably have to commit to buying or making cupcakes, too. Mmm… Cupcakes.)
           
    4. Plan to pregame. Find an ice-breaker activity that works with your theme and helps people loosen up if they have never met before. We find the sillier -- the better, so you don’t end up having this kind of awkward social interaction.
       
    5. Build a better serving station. Make sure you put the buffet table in a convenient place not far from the action but where your guests won’t miss a crucial plot point because someone needed to download some cookies into their stomach cache.

    6. Design a menu to fuel the team. Gear and sprocket cookies? Check.  Watermelon bot? Why not? Package bags of micro chips (tortilla or potato). Party mix can be rebranded as nuts and bolts. Get creative (and silly) or go old-school and order enough pizza for the whole crew. 

    7. Bring your robot! You can show off the skills and talk about your FIRST love with the guests you invited who haven’t been participating – yet.
    Share pictures of your viewing parties by tagging the FIRST® Instagram account or Twitter account.  Tune in for the next episode in the four-episode arc at 8 p.m. EDT/5 p.m. PDT on Mondays and be sure to mark your calendars for the Aug. 15 episode in particular.

    * The Fosters is rated TV-14. Some material may not be suitable for younger viewers.
