Greetings from Hawaii! I haven’t had time to talk or do much on the forum (exams, projects, and working on the design for next year)
Anyway, here are the teams that made it to worlds, most were completely new to VEX or one year veterans (one three year veteran ), and were thrilled on making it this far into the competition.
We had many different ideas at the time, picking up the goals and high hanging were some of them. In the end, the teams decided to focus on just scoring, and practicing that (disregarding 1973A).
Kudos to 1973E for placing 7th in the seeding matches (5th alliance)and making it to quarterfinals in the Math division, but autonomous errors and a “glitchy” drive hindered us, ending our path there. We were alliances with 1763 and 3536D, wonderful teams.
1973C was an amazing contender (39th in the Engineering division) as well, sadly new game objects and broken parts in shipping lead to programming errors (his programmer was not present).
-1973E
A team of two, one programmer/builder, one driver/builder
“Flippy-down” claw (pivots on axle) to descore high goals, powered by one 393 motor
Trapezoid claw shapes to tube, ensures the tube stays parallel to claw
5:7 drive ratio, back is powered by two 393 motors, front is powered by two 269 motors
Prongs exists on front of the robot, allows easy alignment in a position to score on the movable weighted base
4 bar parallelogram arm, powered by four 269 motors, 7:1 ratio
“H” drive for strafe maneuver, middle wheel directly powered by one 393 motor
“Prescore” tube holder on arm and back (skills challenges), also allows preload to be transported while not in the claw
8 rubber bands support arm in going upward
Utilizes one ultrasonic sensor in the front (distance and goal sensing), two shaft encoder (distance, auto-align), and one potentiometer (arm positioning)
LCD screen for selecting 5 different autonomous routines
Two 20 point autonomous programs, scores preload and scores stack on far goal
Two 16 point autonomous programs, scores preload using the arm tube holder, then grabs the stack of two and scores it on a movable weighted base
Ch 8 buttons raise/lower the arm to certain, preset heights
Ch 7 buttons include an “emergency” function stop, and LED pattern function (our programmer got bored :p)
One “ram” autonomous for those moments where the opponent MUST not score
-1973C
A team of two, one programmer/builder (was not present near the competition date), one driver/builder
3 bar parallelogram arm, significantly saves weight (due to this, 1973C goes faster than 1973E and 1973A)
Trapezoid claw shapes to tube, ensures the tube stays parallel to claw
5:7 drive ratio, back is powered by two 393 motors, front is powered by two 269 motors
“H” drive for strafe maneuver, middle wheel directly powered by one 393 motor
“Prescore” tube holder on the back of the robot
6 rubber bands support arm in going upward
Utilizes two shaft encoder (distance, auto-align), and one potentiometer (arm positioning)
LCD screen for selecting 4 different autonomous routines
Two 20 point autonomous programs, scores preload and scores stack on near goal
Two 13 point autonomous programs, scores stack on near goal
Hey guys! You did great at the competition. It was great to see another Hawaii team doing so well.
I’d just like to say that we’re really sorry about the tipping incident that occurred in our qualification match against each other. What we did was in no way intentional and we felt really bad about tipping your robot, especially after your alliance partner getting a tube stuck on their claw in autonomous. For the record, I’m fairly sure that the flip was caused by our arm’s PID code, which was designed to keep the arm at a fixed position even when force was being exerted on it. In an earlier match, when a team with a higher arm than ours tried to force our 4-bar down, it fought back and the force of their lift motors actually flipped them on their back rather than moving our arm. It’s likely that something similar happened in our match against you… it’s unfortunate that it had to end that way, but I guess that’s how the cookie crumbles. Of course, you had no way of knowing about our arm code, so we accept responsibility for the accident. Sorry.
Your robots were great all season long and we really admired your team, especially for being so new to the competition! See you next year!
Was this with 1973C? And in autonomous? Sorry, I don’t remember encountering you guys in the Math division.
Anyway, what happens happens, all is forgiven (we knew you guys weren’t “dirty” players) ,we were all just happy to be there.
Congratulations to the Math division team for obtaining the Amaze award by the way! You guys were always a great contender in the season, becoming our team’s first claw design. Keep on inspiring!
It was incredibly fun to work with 1973E even if it only lasted a short while. You guys had a really efficient robot and it was fun to figure out our strategies knowing that you guys could pull out the high hang if we needed it.
