We've designed a Cougar Workshop Bot.  And the Incredibots have designed an EV3 version.  It's a simple robot designed just for the workshop.  So If you don't already have a robot for the workshop try this one.  You should be able to build it in about 1/2 an hour.  It's the simplest robot we could come up with that could do ALL of the labs.  It's only got 79 parts plus 6 wires.  With 2 light and 2 touch sensors appropriately located you can try out the back-to-wall and advance-to-line programs.

The LEGO Digital Designer file is attached to this article and the printed building instructions are here

And a new EV3 version of the printed building instructions are here. 

Wire as follows:

Left Motor -> B

Right Motor -> C

Left-Front Light Sensor -> 1

Right-Front Light Sensor -> 4

Left-Rear Touch Sensor -> 2

Right-Rear Touch Sensor -> 3

Cougars visit the Columbus Idea Foundry PDF Print E-mail

On Thursday evening, Sept 15, the team went to the Columbus Idea Foundry to take a class on how to use a CNC machine. We were joined by 2 of the team dads and Neils and Eric Hansen from the Lego Lasernauts, an FLL team from Groveport, OH. A CNC machine is a computer-controlled milling machine that can cut 2 or 3 dimensional shapes by spinning router bits at high speeds. Software such as the CAD program that Joey and Alex have learned in school can convert a design into instructions to tell the machine what shape to cut on X, Y and Z axis. 

Dr. Alex Bandar from the Columbus Idea Foundry first gave us a tour of the facility. CIF (http://www.columbusideafoundry.com/) is a a community and do-it-yourself workshop where people have pooled resources so that they can have access to equipment that they otherwise could not afford to use. It is a cooperative machine shop, design studio, artisans community and educational facility. They have all kinds of tools available such as a laser cutter, welding tools, a 3D printer, forge and foundry for casting and blacksmithing, and a woodshop. In addition, there are artists and some small manufacturing and start-up companies that rent studios in the building. There was even a guy working there who is building a completely electric car from scratch! And a Tesla coil...

After the tour, we learned to use the 4’x8’x5” ShopBot CNC machine. We went through the entire process from drawing a sketch to converting the sketch into usable vectors with the software to sending the instructions to the ShopBot to finally cutting out our design in wood. You really need to think through and plan the process to make the cuts in the most logical manner. You even have to take the diameter of the router bit into your calculations. Our test piece had straight and curved edges on the sides, several holes and a shallow pocket. Now that we have taken the class, we are certified to be able to use the ShopBot. Besides wood, the ShopBot can mill thin metals such as aluminum so we now have a way to create parts for our FTC robot!

The Columbus Idea Foundry will be a great resource for the team. We hope to go back and take some more classes so that we can use some of the other tools such as the laser cutter. Thanks to Dr. Bandar for teaching us and showing us all the cool stuff at the CIF.

FTC KickOff at iSPACE in Cincinnati OH PDF Print E-mail
Sunday, 18 September 2011 22:16

 

 

We met at the Diamond’s at 6:45am and loaded up the RV for the drive to iSpace. All of the team except Phil were able to attend the event. Phil was running in his high school cross country meet. We arrived at iSpace a little before 9 a.m. and helped set up the “Get Over It” field.

At 9:30, together with Team 4530 Infinite Resistance, we did a demonstration scrimmage so that the rookie teams could get a feel for what a real match is like before they go to a tournament. When we attended our first scrimmage last year, we were really surprised how crowded the field was when there were four robots in play! When we practiced with just our one robot, our practice field in the garage had seemed spacious by comparison.

At 10:00 a.m., we did our panel presentation on “What Rookie Teams Need to Know”. We gave our key points, shared some of our experiences as a first year team, and then answered questions. We brought in our robot, engineering note book  and scouting notebook so that the participants could see how we approached the challenge last year. After our talk, our team split up so we could go hear some of the other talks. I think that we picked up some good pointers for this year.

At 11:00 a.m., we finally got to see what everyone was waiting for...the new game and field!! Just for fun, we tried to run our robot from “Get Over It” on the new field. Our robot could move the bowling ball and score it on the home area and we could also flip over the crates. All those racquetballs are really going to be a challenge and make driving difficult if they get under the robot and caught in the wheels (our first design challenge). 

During the rest of the afternoon, we helped teams with building and programming. By the end of the day, several of the rookie teams had robots that they could drive around. We ended the day by going with Elizabeth and Matthew Worsham for ice cream and a hike in one of the local parks. 

Thanks to Linda Neenan and everyone at iSpace for the great FTC Kick Off event. I think that we are all off to a great start for this season. 


Cougars,

 

Thanks so much for helping out at the FTC kick-off this weekend.  We heard from several of the rookie team members (and some of the more experienced teams as well) how helpful the information you shared with them was.  We heard one comment that went something like this.  “Just getting to see what the Cougar’s robot could do made this worthwhile.”  We really appreciate your willingness to spend a whole day giving tips to other teams. 

 

You’ve come a long way since your rookie season last year and we here at iSPACE wish you a very successful 2011-12 FTC season.

 

Linda

Cougars At FIRST World Festival PDF Print E-mail
Written by The Cougars   
Wednesday, 04 May 2011 18:57


FTC (FIRST Tech Challenge) is a FIRST (usfirst.org) international robotics competition targeted at high school students. Teams of up to 10 students build robots using TETRIX, LEGO, and custom fabricated components. The robots can measure up to 18" x 18" x 18". Four robots, two teams of two robots, compete against each other on a 12' x 12' playing field.

Cougar 2010-2011 "Get Over It!" Season Summary:
  • Approximately 1600 teams competed in FTC this year.
  • Ohio State Championship
    • 32 teams attended the Ohio State Championship tournament at iSpace in Cincinnati.
    • The Cougars finished the qualifying rounds in 3rd place, and as an alliance captain selected the teams of Python from MI and Trash Torque from the Wellington school in Columbus as their alliance partners.
    • The Cougars alliance went on to win the Ohio Championship and as captain of the winning alliance the Cougars qualified to attend the World Championship.
    • The Cougars also won the Rockwell Collins Innovate Award. "The Rockwell Collins Innovate Award celebrates a team that not only thinks outside the box, but also has the ingenuity and inventiveness to make their designs come to life. This award is given to the team that has the most innovative and creative robot design solution to any or all specific field elements or components in the FIRST Tech Challenge game. Elements of this award include elegant design, robustness, and ‘out of the box’ thinking related to design. This award may address the design of the whole robot, or of a sub-assembly attached to the robot. The creative component must work consistently, but a robot does not have to work all the time during matches to be considered for this award. The team’s Engineering Notebook should be marked with journal entries to show the design of the component(s) and the team’s robot in order to be eligible for this award, and entries should describe succinctly how the team arrived at that solution."
  • World Championship
    • 128 teams qualified to go to the FTC World Championship, held at the FIRST World Festival in St. Louis.
    • The 128 teams were divided into 2 64 team divisions, Franklin and Edison, for the qualifying rounds of the World Championship.
    • The Cougars recorded 5 wins and 2 losses during the qualifying rounds to place 12th in the Franklin division.
    • The top 4 seeded teams get to pick partners to form 3 team alliances to compete in the finals.
    • The #1 seed Bounty Hunters #2864 from Staten Island NY selected Say Watt? #3539 from Edison NJ (1st pick in alliance selections) and the Cougars #4251 (5th pick in the alliance selections) as their alliance partners for the finals. 
    • Our alliance lost in the 3rd game of a 2 out of 3 match in the semi-finals to the alliance of SD30 from Montana, the Wreckers from Westport CT, and MITibot of Lexington MA who went on to win the World Championship.
    • To top it all off we were nominated for the Motivate Award. "This award celebrates the team that exemplifies the essence of the FIRST Tech Challenge competition through team spirit and enthusiasm. They show their spirit through costumes and fun outfits, a team cheer or outstanding spirit. This team has also made a collective effort to make FIRST known throughout their school and community."
The Cougars Robotics Team had a tremendous rookie season. We learned to build significantly more sophisticated robots. We learned to program in 2 new languages, LabVIEW and Robot-C. We learned to make alliances and work with other teams. And as a rookie team we made it all the way to the semi-finals of the World Championship. We're looking forward to next year's competition!

  • Exciting Changes to Match Play
    Over the past decade, FIRST® Tech Challenge has continued to grow, serving the FIRST mission of creating excitement and exposing students to the wonderful world of science, technology, engineering and math. With growth, must come change, as most of our community has seen through our evolution of robot technology. We continue to work to make this program more accessible and affordable, while still engaging and challenging students of all skill levels.


    Since the 2015 season, FIRSTTech Challenge has moved away from a centralized control system to the Android based platform you see today. The increased reliability of the Android based/REV platform, is allowing us to improve the flow of the matches. We are making significant and exciting changes that teams and volunteers need to be aware of for the 2017-2018 season.



    Autonomous to Driver Controlled Transition

    Starting in the 2017-2018 season, there will no longer be a hard stop following the autonomous period to transition to the driver controlled period of the match. Once the autonomous portion of the match ends, the emcee/game announcer will tell the teams to pick up their driver station. As a visual cue, the scoring system will display to teams that they must pick up their driver station. Teams will only have 5 seconds to pick up their driver station, so they should make sure to pay close attention! After the 5 seconds, there will be a 3-2-1 countdown and the driver controlled period of the match will begin right away.

    Why make the change?
    • Since the reliability of our technology has come so far, the large gap between autonomous and driver controlled periods of the match is no longer necessary.
    • The game design doesn’t require field reset between the autonomous and driver controlled periods.
    • The shortened break between autonomous to driver controlled period increases engagement by keeping the excitement of the match going.
    • The shortened break will encourage teams to build smarter and create sturdier robots, that can move successfully from autonomous to driver controlled unhindered.
    What does this mean to teams?

    Teams must remember is to keep an eye on the match timer display, and listen for the cues from the Emcee or Game Announcer to pick up their driver stations. The transition will happen quickly, and the scoring system will automatically run the rest of the match. Since the robots are not tied directly to the scoring system, teams must make sure they are ready to run their driver controlled programs after the 3-2-1 countdown.

    How does this impact the number of matches played?

    This will not impact the number of matches played at an event. From League Meets to State Championships, teams will still be able to play between 5 and 6 matches, depending on the specific tournament. Teams will still receive a minimum of 7 minutes between each match. Super Regionals and World Championship events will have additional matches. The number of matches at these events will be announced at a later date.

    Up righting/Untangling/Reconnecting Robots

    Because of the shortened transition from autonomous to driver controlled period, field personnel will no longer enter the field to upright or untangle any robots. Robots that have lost connections will not be reconnected by the Field Technical Adviser. Teams should take this into consideration when building and designing their robot.

    If you have any questions about the new changes to our match play format please email ftcteams@firstinspires.org. Happy Relic Recovering!
