No, this is far different than a four bar. for example it starts with all bars horizantal, ends with all four vertical, and has a 5.8 to 1 extended height to compressed height ratio. Watch the youtube more, look more. I will also post more detailed pics in future.
And, by the way, my name is not Danny, he is on a different team at my school.
We are going to be building 3 robots over the summer and deciding which one has the best potential to be the platform we choose to continue with. We will have something fairly simple for Hawaii, but we will complete a 7 bar Peaucellier planar linkage lift over the summer just for grins.
Lol it’s a double four bar with horizontal/ vertical capability which is not too hard to accomplish. It’s not a new lift design. Double four bars might work this year but they have a lot of slack.
You can see that the pivot points are offset to go vertical.
The vertibar concept was already used this year in Toss Up by both 2059A and us, so you haven’t made anything inherently new by combining the two together. I do appreciate that you’re trying to find new lift designs though!](http://puu.sh/8qCfC)
The problem with a ‘Danny Bar’ is that it can’t go below itself which cuts the height potential in half. I like to think of them as ‘half scissors’. they definitely have their applications though.
While this lift mechanism may not have been used much in vex, I can absolutely guarantee you with 100% certainty that this kind of mechanism as existed for a long long time. Just because you have not seen a high school robotics team use the exact same version as yours before, does not mean that it is a brand new idea that has never existed in the world and you should name it after yourself.
