 For me, this is the most powerful message of FIRST, that people can come together and work together to achieve so much, and leave old rivalries, grudges, and hard feelings behind. When people talk about culture change, this is what I hope for. - Aren Siekmeier [more] |

322 Three speed transmission.
I found this picture of our transmission for those who didn't get a chance to see it at the Nationals. The picture doesn't show the cylinders used to move the shift levers. The transmission is actually a four speed but two of the speeds are the same. Next year we may use all four speeds depending on what the game is or remove one stage and just make it a two speed.

More questions
I'm still trying to figure out how this thing works also. It looks like the right and left sides are independent from each other and are simply mirror images. Also, it looks like the gears might shift on the fly.
What I don't understand is how the power gets transferred from the first (inside) stage to the second (outside) stage. dkeith, can you throw us a bone here? Andy B. |

More pictures
Here is a screen shot from AutoCad inventor. This picture shows the motor mount case and the gear configuration. All the case does is let me fit the motors in the robot. The transmission was wide enough that the motors had to be placed parallel to the transmission. The large gear is used to transmitt the motor power to the transmission while keeping the motor clear of the transmission case. The stepped piece is the Attwood gear drawn with no detail to make the design go quicker. The gear shown closest to the camera is the transmission input gear.
Yes, I have prints for everything drawn in Autocad Inventor. This is a very nice program. Inventor allowed me to turn gears and move shifters and see what would happen as well as keep track of weight. I had used Unigraphics before so the transistion to this 3-D package when fairly smooth. |
