Shelton to be Added to Washington Team Map

By the end of April, once the competition season is over, Washington FIRST Robotics will add a pin at Shelton to show the primary location of 4-H Team 5295 "Aldernating Current" FIRST Robotics of Mason County. This will be the first time in three years our Shelton team shows up on the Washington team map.

Solutions to Communication Problems

Sometimes our drive station operator console does not talk to the wireless radio. We experienced this most recently March 26th at our test at Olympia Robotics Federation test field in Tumwater.

Sean F. (student Lead Programmer for Olympia's Team 4450) suggests
1) Unplug roboRIO at radio. Plug directly into a computer.
       Wait 20 seconds. This should refresh the IP address.
2) Plug roboRIO back into radio. This may fix the problem.

When the above does not work, K.O'Connor (FRC Robotics Engineer at forums.usfirst.org) suggests
3) Set drive station IP to 10.TE.AM.5 (TE.AM = 52.95)
     Instructions to Reimage RIO
4) Make sure the adapter is not dual homed. Follow These Steps
5) Disable Windows Firewall. Instructions at Bottom of this Link

6) L.Spoldi of Team 230 Gaelhawks of Shelton High School in Shelton, Connecticut adds
(6A)As noted above, I would strongly suggest verifying that your Windows Firewall is turned off.  You should also disable any networking configurations that are not being used (eg. Local Area Connection is not being used when connect through the WiFi).  Also make sure that you have successfully re-programmed the new OpenMesh radio after your competition.  This is required to reset the WPA key to allow the wireless communication.  Note that you can verify the basic interface by plugging the driver station into the radio with an ethernet cable.  Make sure that the connection to the roboRIO is plugged into the ethernet port that is next to the power connector.  This is also very important. 

(6B)The version of windows running on your driver station may be a factor.  There have been several teams that have had issues with Windows 10 but I believe they were all fixed with the latest driver station software update (https://decibel.ni.com/content/docs/DOC-46527).

(6C)In addition there are several threads on chiefdelphi.com that provide additional tests that can be performed to validate and test the communications.

Review of Auburn Mountainview

To best prepare for our district competition on April 1-2-3 at Auburn Senior High School, let's ask ourselves a few questions.

What went right?
DRIVE TEAM: Our robot "Ironwood" drove over a rock wall and successfully parked at the tower. PIT CREW: After qualification match 6, the pit crew was able to get the tread back on the robot, missing only one match. After match 18, Hunter was able to give the driver the ability to use our camera to see around obstacles.   

What went wrong?
Treads kept falling off. Tread bearings broke and we had no spares.  Also we did not use an autonomous program.

What did we learn?
Only use drive systems other FRC teams used with success. Bring spares of all parts to competitions.  Write an autonomous program.

What can we learn from other teams?
Our sister 4-H Team 3787 Westport Wild Robotocats successfully overcame both the Portcullis (A1) and the Sally Port(C2). Our parent Team 4450 Olympia Robotics Federation was the #2 scorer after the dozen qualification matches. They had difficulty against a defensive robot in their three quarterfinal matches losing two matches by just three points!  Although Team 4450 wrote three autonomous programs, none were ever used. In Autonomous a team gets ten points just for crossing an undamaged defense.

How can we do better?
Build our robots from kits that other FIRST Robotic Competition (FRC) teams used with success.

What are our resources to test?
In our robot cage - thanks primarily to A.Hospador - we have a Low Bar, Moat (B1), Rock Wall (D1), and Rough Terrain (D2).  Team 4450 invited Team 5295 to use their half field in a warehouse close to Capital High School in Olympia.  Team 2557 SOTAbots has a full size field in Tacoma that is open to everyone.  Probably the best days for a field trip to a test facility is Saturday March 19 or Saturday March 26.

Robot Breaks in Fourth Match; Team Finishes 35th of 40 in Qualification Matches at Auburn Mountainview March 3-5

SUMMARY: Our competition robot "Ironwood" broke down in qualification match 24.  Both tank tread bearings failed; we did not have spares. We plan to replace the tread with (8) six inch diameter tires. Three of the six robots in the final championship match at Auburn Mountainview used the 8 x 6" pneumatic wheel configuration.  The team's heart broke when we discovered we could not repair the robot in time to compete in another qualification match.  The team competed with a human player in eight of the nine other qualification matches (without a robot) and finished 35th in a field of 40 teams.  In 2015 with a functioning robot, Team 5295 finished 31st out of 32 teams. The team is upbeat about repairing our robot.  The team will begin continue repairing the robot on Thursday, March 10th in robot shop room 809.  Team 5295 did not win any awards. 

ATTENDING: Ten students and seven adult mentors attended. Students: Brayden (Pit Team), Brooklyn (Graphics Lead), Guy (Drive Team), Hunter (Programming Lead & Drive Team), Isaac (first year), Jaeden (Drive Team, Pit Chief, & Build Captain), Jonathan (first year), Juan (Pit Team), Kiery (Drive Captain & Team Captain), and Tyler (Safety Captain).  Mentors: K.Hansen, A.Hospador, G.Inman, Je.Ordonez, Jo.Ordonez, A.Walker, and Coach Wright.

EVENT RESULTS: http://frc-events.firstinspires.org/2016/WAAMV 
The team went 0-4 with the robot and 4-3 without it for an overall record of 4-7.

UNBAG, WEIGHT & SIZE: Upon arriving at Auburn Mountainview High on Day 1 Thursday, the robot inspectors allowed students to unbag our competition robot "Ironwood" asking them to return when the robot frame was fully attached. The robot perimeter measured 118.75" < 120" maximum requirement (rule Robot03). "Ironwood" weighed 95 pounds < 120 pound maximum requirement (rule Robot20).  Brooklyn (with help from Juan and 1.5 other team members)  created a reversible red/blue bumper that weighed 10.8 pounds < 20 pound maximum requirement (rule Robot05). 

ROBOT INSPECTION: This is an iterative process. After our initial inspection, the team needed to: touch-up bumper color; fix the boulder motor slippage; update the drive station software; check the arm motor; install the plexi-glass; check all the electrical wires for any disconnects; and grease gears. The pit team included Jaeden (Pit Chief), Hunter, Isaac, Juan, Kiery, and Tyler.  By the end of evening on Day 1 (pits closed at 9:30PM), we had only to add some red and blue gaffers tape to make the bumper colors uniform, and complete a parts list (PL).  Engineering firms call this a parts list, last year FIRST called it a bill of materials (BOM). This year FIRST calls it a Cost Accounting Worksheet (CAW).  Whatever you call it, it simply documents what components (in addition to the Kit of Parts) the team used to build the robot. A.Walker provided a dinner of sandwiches (turkey, ham, and swiss) and fruit in the high school cafeteria. In the morning of Day 2, Brayden joined the pit team.  Kiery coordinated with robot inspector K.Luthy to pass robot inspection.

SCOUTING: While the pit team made final adjustments to "Ironwood" on Day 1, Kiery and Jaeden organized a scout survey.  In a visit to each pit, our students asked students from other teams whether their robot could make low goals, high goals, climb the tower, or overcome obstacles.  On the morning of Day 3, Guy shared that most of the robots had difficulty with the three gates: Portcullis (A1); Drawbridge (C1); and Sally Port (C2).  A.Walker notes that teams also had difficulty with the Cheval de Frise (A2) and the Rough Terrain (D2).  In the final match of the two best alliances, robots sped across the Moat (B1) and Rock Wall (D1),

DRIVE TEAM: Team Captain Kiery organized the drive team: Guy (human player); Hunter (programming); Jaeden (joystick driver); and Kiery (drive captain). After "Ironwood" broke down, Guy and Brayden represented the team as our Human Player.  This allowed the team to receive the points that the two robot alliance won, including wins.  The team went 0-4 with the robot and 4-3 without it for an overall record of 4-7.

MATCH 6: During our initial match (a 32-55 loss), the right tread fell off. The pit team repaired this and "Ironwood" was ready to go for our third match.

MATCH 9: The pit team could not repair the tread in time for the match start. Guy attended as the Human Player. We lost the match 5-66.  We did pick up five points helping our averages.  Without the human player we would receive zero points and an automatic loss no matter what our alliance did. 

MATCH 18: We lost our third match 55-83. Jaeden successfully drove over the Rock Wall (D1) defense and parked at the tower. Our driver Jaeden lost sight of the robot when it went behind a tall obstacle. Hunter figured out how to give a camera feed to our drivers station.

MATCH 31: We lost our fourth match 12-55, shortly after the left tread became loose and fell off.  The pit crew determined that two small bearings failed, one each side.

REPAIR: The pit team felt the best repair would be to replace the tread with pneumatic wheels. While Team 5295 did not bring our 6" pneumatic wheels with us, we felt sure that another team did.  It was also likely that the machine shop would be able to make some parts for us.  The machine shop also probably had some raw material we could use.  Build mentor K.Hansen felt that the quickest repair involved machining the six required plates in his Shelton garage and getting the pneumatic wheels from our robot cage at Shelton High.  He, Coach Wright, Brayden, Jaeden, and Juan returned to Shelton late afternoon on Day 2.

RULE  R18: A.Mendes, a lead robot inspector that trained A.Walker as a robot inspector, dropped our pit for a visit. Mendes pointed out that rule R18 allows 30 pounds of pre-fabricated parts only at load-in. "The WITHHOLDING ALLOWANCE may only be brought into the Venue when the Team initially loads in at the Event. Items made at an Event do not count towards this weight limit." Our plan to make parts in Shelton and install them on the robot is illegal per R18.

MATCH PLAY WITH HUMAN PLAYER (NO ROBOT):
Q31: 12-56 loss as Red2.
Q37: 65-52 WIN as Blue1.
Q43: 30-74 loss as Blue 2.
Q49: 67-62 WIN as Red2.
Q57: No human player. Loss; 0 points. A.Walker insisted we go to dinner.
Q62: 65-64 WIN as Blue2. (Saturday)
Q67: 90-86 WIN as Red2. (Saturday)
Q73: 59-84 loss as Blue1. (Saturday)
