OKAY, most people have seen our world cup robot (opportunity) and we got alot of questions, so im gonna do a full release here of opportunity, and its bigger brother Sloth, Sloth V2 has just been made so im allowed to release sloth V1 (which played at the christmas scrimmage in NZ)
Opportunity served our team well, and was a great predecessor of Henry - released here https://vexforum.com/t/lynfield-college-robotics-2915a-first-gateway-robot/19544/1&highlight=lynfield
Opportunity won us only one competition though, with it reaching the finals in all but 1 (where we versed the people who won it in semis)
Opportunity V1 had alot of issues (as do all of our V1 robots) - the main issue it had was TIPPYNESS which from watching youtube videos, alot of teams suffer from this year - Opp V1 is shown below

We fixed these problems by making the arm alot shorter and moving the main towers to the center of the robot, balancing the weigh more evenly.
resulting in V2 shown here - http://www.youtube.com/watch?v=PMTXPcej_z4&feature=g-upl&context=G2f6afb9AUAAAAAAADAA
There are a few features on this robot which no one picked up when watching videos… i think they were pretty awesome.
WINGSSSSSS. These were VERY controversial, i think mainly because we put them on half way through world cup to keep them a secret… the wings were 12" chassis rails on pneumatics that flicked down as blockers, making our robot essentially 42" wide to hinder movement of opporsition, they flicked up and down so it didnt hinder us.
BACKWARDS SCORING… This is a nifty little feature which we didnt quite get perfected. The purpose of this, is to score the center 30" goal from the isolation goal (Sloth is designed around this), because if you watch games closely, that center 30 is the decider half the time, and isolation robots are generally racing each other there… so why not score it from iso?
Opp motor configuration was as follows -
1 HS motor on each side of the lift
1HS and 2 269 on either side of drive
2 269 on intake
The lift was a chain linkage thingy ma boby (do we have a proper name yet?) on a 1:6 ratio
Where to begin… i dont know what to say, i really dont want to write it all out… in short we had 18 autonomous programs (9 for each color)
And thats about all there is to opportunity…
Sloth V1 only entered one competition, and was plagued with problems (hence the redesign) but still managed to fight its way to finals. It was designed to score the center 30" goal from isolation
it is shown below running its autonomous routine -
It had the same motor layout as opp, yet only one autonomous as we didnt have enough time to write more. We took what we learnt developing opportunity and implemented in on sloth, hence the tower in the center. We opted for a 6 bar for strength and stability over the chain linkage. That pretty much sums Sloth up, sorry i cant say any more about sloth as we are still very protective of him… So i may have very brief answers if you ask questions
Wow, my longest post ever… Hope we can be of some help with people still building and designing](http://www.youtube.com/watch?v=bmxodldQMhY&feature=g-upl&context=G2cd2bf5AUAAAAAAAAAA)
