Quick question, how many teams were able to scale the tower??? We (4980) successfully scaled the tower many times and I am wondering because we were the only ones at PNW West Valley that could scale.
Four out of thirty teams were able to scale at Guilford. 3506, Yeti, was able to do it reliably; the other ones were somewhat unreliable. Our team is planning on modifying our arm to help us scale.
Based on this fourm: http://www.chiefdelphi.com/forums/showthread.php?t=145323 The average scaling success rate was 3%. At the Kettering #1 District Event I remember two or three teams with successful climbers. There was maybe five or six teams that attempted scaling to various degrees of success. The team next to us in the pits actually ended up taking their entier scaling mechanism off of their robot due to it not working. My team plans on adding a scaling mechanism in the next two weeks before our second competition.
Both my team (708) and Team 341 could scale at Hatboro.
according to mojo371’s statistics,
https://docs.google.com/spreadsheets/d/1SggFEb5otIq6_7vr_J-QGUfbyHrDHp_h4JjioaOje6o/pubhtml
for the matches so far, about 2-5% of scaling opportunities resulted in a successful scale.
I expect this to improve greatly as the season progresses.
In San Diego we scaled 3 times all the way up as a low bot but only got credit once. first time last Q match we went up 2 seconds early… next time in QF we scored. Last time in SF we went too far up and slipped back down. Pretty much every qualification match we tried and failed as field was way different than practice wood items.
Scaling is very hard and we did not have a solution until last week …then we tried in qualification match and finally figured it out on the actual field of play.
There were three other bots that could scale .
Its hard unless scaling is part of the bot design from the get go…for us it was a major subsystem an we worked every build week to figure it out finally had two revelations of how to do it last week (we almost didn’t want to go to CV because we were struggling with it so much)…then it worked first in practice day at San Diego and should work in CV this week from our first match on.
the 2% number is a really bad one. It would appear that a robot being on the field counted as an “opportunity” to scale. That is not anything close to an accurate success rate.
Warning wild guesses ahead:
From the anecdotal evidence gleaned from watching Palmetto and day 1 of the Toronto regional via live stream, the number robots that have climbers and attempted climbing is somewhere around double to triple the success rate listed in that spread sheet. From that we can GUESS that around 4-10% of robots currently intended to climb. This may change later as more and more teams start to utilize their withholding allowance to build climbers but the success rate relative to the number of total teams intending to climb will go down for a few weeks then go up during week 7 and at worlds.
