Our estimated finished weight will be between 110lbs to 115 lbs.
Check back in two days for hint #2 Shawn Team 60 Last edited by Shawn60 : 26-01-2003 at 22:27. |

No problem. You will need to go the gallery for some of the other clues.

Clue #2
Ken
Go to the gallery and you can see a couple of pictures of our gear box in a semi complete form. What do you think? http://www.chiefdelphi.com/forums/pi...DESC&sort=date Shawn 60 ps In a couple of days I will post a completed gear box. Last edited by Shawn60 : 27-01-2003 at 23:14. |

So far, pretty good
. One semi complete transmission done on the 19th. Not bad at all. Just need at most 1 more week to finish this one. Let's see, I like the shape, it save lots of weight by cutting away the corners... Ah, 2 place for motors to screw in, so its a transmission for two motors... Probably just one side of the robot, so your robot will have 4 motors for the drive system huh? On to the next picture... The sprocket on the most right is the last stage of the gear box, connecting to a shaft transmitting power to the wheels. The middle 2 gear is the 2 speed sprocket, each level representing one individual gear ratio.... The shaft next to it is where the magic happen. By sliding that shaft with 3 gears on it, you engage one set of gear at a time. The middle gear with the top gear on the right, or the bottom gear with the bottom gear on the right. On the other end of this shaft is where the motors get connected to. The shaft slightly behind all three of the others is where the 2nd motor connect to. It connect with the left most shaft on the top gear, and transmit power from the second motor to that shaft by meshing the teeth on the top gear. Not sure if you want to, but I bet it can leave that shaft alone by using the pneumatics to slide it off the top gear and clear the rest of the transmission. Pretty nice gear box this year . Just make sure its completed. |

Hmmm it looks as if there are 2 pneumatic actuators on the gearbox? NO?
the only 2 reasons in think there are 2 pneumatic actuators in the picture are A) the second pneumatic actuator is just being held up by there for reasons of not wanting to pu it down? B) the gearbox utilizez 2 actuator in which case i would assume its a 3 speed robot? NO? |

Now...here's the thing...
If the photo shows two pneumatic pistons, they'd be allowed only a single other custom cylinder. Those are each small bore, small stroke pistons, and thus, a custom order. As per the rules, they wouldn't be able to order the two additional pistons necessary to make a second transmission for the other side of their robot. So, based on that, and that each plate of the gearbox is alike, I'll guess that the motors (four, probably) all attach to a single gearbox. This, of course, requires that their robot be only 2WD, or that it be 4WD with a differential. I'd imagine it's the latter. |

What is our strategy?
Ken...
I am going to put up the finished gear box tonight. Can you make a repeat and not only explain the gearbox but also come up with a possible strategy of our robot? Good Luck ![]() Shawn Last edited by Shawn60 : 29-01-2003 at 23:13. |

I wish 247 could be underweight, but...with 2.1 pound wheels ( i'm not saying how many ) before "speed holes"....we are going to be right at that weight limit

Here you go Ken
Here is the final gear box.
