Re: pic: 6 wheel suspension

Drawings are at http://www.team1322.org/ideas.htm under "six wheel omni".

It is semi independent suspension on all wheels but the right is separate from the left. Because the frame attaches at the two point’s center of each drive half (between the omni and mecanum) the frame lifts about half of the front wheel rise. No springs are required, the weight of the robot should keep it all down. We may add springs later if needed. We are thinking that we could add pneumatic control to help with it, also use it to lift the front wheels to get up onto a step. The weight is approximately 25 lbs for each drive assembly.

Re: pic: 6 wheel suspension

Very cool, not technically a suspension, but a flexing chassis (the only reason why i say that is because I work on cars all day at College). Although it is the closest thing to a suspension right now FIRST wise (from what I have seen). That idea would of be ideal for 2006 and 2007, maybe even 2009 if there is some sort of steep incline.

Like i said very cool and should come in VERY handy in the future since FIRST likes to use rams in some aspects of the games in the past.

Re: pic: 6 wheel suspension

looks nice, although it might obstruct manipulator mounting. do you not need chain tensioners?

Re: pic: 6 wheel suspension

We have the sprockets and wraped the chain around them and worked out the distance. For the #35 chain it was 15in +/- 1/16. Doing this we do not need to tension the chain. Add a link than add 3/8 in, add two links add 3/4in.....

The game commin up will determin how we will attach the arms.
