woo is amazing, im new here, may be we must go to Guadalajara Mexico this year....some spke spañish here?

Your robot is not huge its structure is not very innovative, but I must say im impressed your robot's ability to do a lot of missions really quickly with the same attachments is absolutely amazing, also you got some creative solutions really like that the main attachment you use is so simple. In my opinion you are one of the most impressive teams of the year and I believe that if you can change a bit of things in the run you will be able to reach max points fairly easily, great gob!

Coach in upstate NY here - your precision in driving is beautiful. Are you using gyro straights & turns, and black/white line following with color sensors, as well? To what else do you attribute your accuracy? Wonderful work!

[@NitrousGasMan]

We use a PID gyro algorithm to ensure accurate straight driving and turns. Each movement has an acceleration and deceleration phase to minimize wheelspin and skidding. There are two colour sensors on our robot but we ended up not using them this year, as there are very few useful lines on the mat. We found that the gyro sufficed and was faster than line following. In previous years, we used the colour sensor to stop at and square to a line, but this year's mat was too colourful and some lines only had a white background on one side. We also square up to mission models at 0.25, 1:10, 1:39 and 1:56 and the wall at 2:10 to reset the robot's orientation after driving longer distances to correct for errors.

@@NitrousGasMan - would you or teammates, or your mentors/coaches be willing to visit with two of our team members from 22251 Children of Apollo and a coach or two to discuss PID control and accel/decel.? We had some skidding issues on Saturday at qualifiers on 'fresh' mats, and would like to learn from another team as we grow. Would that be possible? This is Coach Mike with Apollo, my daughters (12 and 10) are members of the team; their older brothers are part of FTC 5356 TARDIS.

@@MLSimons1 Hi Mike, Our team does a lot of outreach and we would love to meet up with your team. One of the other coaches runs our email and you can contact us at [e-mail] to set up a time.

One thing how many motors are you using

[@NitrousGasMan]

We use 4 large motors. Two are the drive motors. One operates the rectangular arm at the rear of the robot. The last one controls the front arm and is also used to drive the gear for the chicken mission.
