Single or Dual Speed Transmissions ?
Does anyone have thoughts or insights regarding using a 2 speed super shifter for this years game.
Shifting to a lower gear ratio would probably help during the balancing and the higher one to zip around the field while shooting. Probably not a s simple as that, but that is the only use I see this year and will stay away from it.
I know the main reason for me suggesting them to my team is for the benefit of the slow speed on the bridge, it could be a real help in balancing
The low gear ratio might help if you decide to cross the bump. Since hitting the bump at speed and using the momentum to carry you over might be rather disastrous for your wheels/frame, low gear could give you the torque to crawl over.
I see dual speed being an advantage this year. In 07 bots with ramps were almost useless with single speed partners. With the bridges and very little room to move(with multiple bots) a very slow low gear will probably be a huge advantage.
I think it might be a great year for the supershifter… since 10W 1" stroke solenoids are allowed, I was surprised AM hasn’t made a solenoid shift kit…
In 2001, teams 60 and 254 had 2 major advantages with regards to the bridge vs everyone else, generally speaking at SVR that year.
6 wheel drive for stability and a multispeed transmission to quickly balance, using low gear.
It was clearly an advantage, since 2001 was a timed game to win.
I think using one this season has its merits.
This year seems like a great one for Shifters.
And with AndyMark it is quite easy to get them.
We are defininty heavily considering them, the only issue is being the high price.
This is an awsome match from '01. Watch for 60 going over the barrier and 254 balancing(they were both 4WD).
This was the alliances best match.
I notice that the bridge that year stayed down while this years bridges stay balanced. That tells me that it will be harder to get on the bridge but easier to balance once on.
I must be getting old.
I was there and we were with them.
mixing up recall of memory
The way I see it, there will be people trying to knock you around no matter what game it is. You might even be blocked trying to get into the key. A low gear transmission can let you push through any blockers especially when you have high traction wheels. ALso it is good for balancing when you can push your teammates to the right balance.
The SuperShifters cost an arm and a leg compared to CIMples or ToughBoxes, but I feel low gear is going to be big this year. I know we will be using them, unless something else happens.
We were thinking of a “pseudo 2 speed gearbox”. By that, I mean we’ll be using a single speed CIMple box geared for high speed, but add a button to drastically decrease our speed. We don’t think we’ll need a lot of torque primarily from the gearbox itself, and we doubt we’ll get into any (major) pushing matches, so we think the wheels we’re using and the “low speed” button we have will solve those problems.
Yahtzee. If slower speed is what you desire, rather than a higher torque, that can be accomplished simply and cheaply via software.
That’s what we’re doing. Just press and hold a button and the speed is run at a fraction of the high speed. We used it last year for precision movements, and to make wide turns easier. Loved it then, so we agreed to use it now.
However, I think torque is super important considering the lenient defensive rules. Gotta be able to counter defend.
im new here and i dont know what does a single or dual speed transmissions mean, what does it do andwhat is it useful for?
Yeah, but with most all of the 7-9 strategies we have planned out, our robot isn’t going to have much robot-on-robot action. It will have sufficient torque to do some pushing, however We plan on be passively defensive, or T-boning teams, since most of them won’t be able to defend that way.
Our “special” wheels will help, too, as standard traction wheels won’t get as much grip as them. 
A transmission is like a gearbox. You put motors into it and it adjusts the speed of the motors that go to the wheels. Normally, it’s just the one motor speed, however there are certain advanced ones that can make 2 different speeds.

Think of a car and how when traveling at low speeds the engine can rev at high rpm’s, and at higher speeds the engine can rev at lower rpm’s.
Some teams take this concept and use it for their drive trains. Its very useful because it allows for higher speeds and more maneuverable control than a single-speed.
