Team 1711 prototype
http://www.flickr.com/photos/23220170@N07/
Heres a few images of the robot design we've created. The "jaws" are pneumatically operated and grab the ball loading it to the arm. When the arm is raised the ball is parallel with the over pass and the upper jaw launches it over. We originally were going to use 2 tread wheels and 2 mechanums but then opted for all mechanum. Questions comments or suggestion are appreciated. |

Re: Team 1711 prototype
looks awesome!
do you stay within the 80" rule? |

Re: Team 1711 prototype
we stretch out to 81 inches when the arm lifts up and is in possession of a ball. Luckily its the third week so we can adjust for that

Re: Team 1711 prototype
Very clever design! I'd love to see a movie of it doing it's thing, it looks like it would be very fun to watch.

Re: Team 1711 prototype
No it's not. You may not have any two points more than 80" apart (horizontally). |

Re: Team 1711 prototype
That's neat! uses up a lot of air though, doesn't it? we are also dealing with air consumption issues

Re: Team 1711 prototype
We've been thru the 80" rule discussion in a few different threads...and the Q&A addresses it also....the circle thing is an example, but the rule says only that you can't have two points further apart than 80" in a horizontal direction.
Measuring this can be a bit difficult. |

Re: Team 1711 prototype
we have a freakishly similar design....may i ask what material you used for the "jaw"....also how do you close it up to fit inside starting position.....congratulations on an amazing looking robot
here is our design (sadly we dont have anyone experienced with CAD) so we use chalk and a board...the design is to scale..we have a protoype, much like yours except with a different method of gripping the ball (we used PVC...i dont personally like the pvc idea i like yours much better) ![]() |

Re: Team 1711 prototype
oh and can i reccomend you use the same tread that u used for the traction wheels as ball "grippers" they grab the ball like no other

Re: Team 1711 prototype
We used 1" electrical conduit and a pipe bender. Also, if you use conduit, DO NOT DRILL THROUGH IT or flatten it. Use pipe clams to avoid creating potential failure points. Note: Last year at the Michigan regional a team constructed an arm out of PVC and it snapped.
