I can't take much credit for this, I just copied it from 469 with a few tweaks. I would say it worked pretty well for them, world championship and such things. Not sure any one was questioning the reliability of their drive train, hats off to them, they are an inspiration to all teams. |

Also, bumper support on a WCD doesn't need to be complicated. As for interfacing to mechanisms, how is it more difficult with a WCD? |

We make one piece bumpers with strong corners. Any moment trying to bend the bumper over is reacted by the adjacent section. |

Re: pic: Concept 6W Drive Train
In recenty memory, there have been:
2010: Giant bumps made moving fast only possible in the individual sections 2011: Open space for driving. Very fast driving was useful. 2012: Open space for driving, except when passing over the low barrier. 2013: Open space barring the pyramids. 2014: Totally open space. 1678 was geared for 22fps according to their website. If you feel that the cost/complexity is beyond the team's scope, sigle speed is more than fine. But when running 6 cims, be prepared to add in some kind of anti-breaker tripping code anyway just in case. |

Re: pic: Concept 6W Drive Train
You may want to consider what would happen if this chassis is used in a game that allowed high speed and hard hitting, like this years. There is the possibility that the vertical angle pieces in the corners deform when hit on that corner causing the two outermost side tubes to move backward. Since it looks like your axles are supported by the lower side tube, they may bind in the bearing blocks and/or cause the robot to not drive straight.

Re: pic: Concept 6W Drive Train
Shafts were 7075 1/2 hex.
Sloppy is probably the wrong description, more flexible than anything. The top of the side plates had some decent flex in direction changes. I like the suggestion for removing the upper inner support, ithink that could easily change depending on the game and mechanisms required. Quote:
