Back to my points about spacing the plates. I think I get it. The pictures are a big help, but I don't have the CAD in my head so I could be screwed up still. In general, I think it is pretty nice. I like that you have options if you see flexing. I am anxious to see the movie of your robot floating around gamefield. Thanks for sharing your experience with us, M. Joe J. |
Re: pic: Mecanum Wheel Module Gearbox
haha... then you'd better give them their own mock-up to play with early... (thats what our team did this year... and we didn't have to spend the bus ride to pittsburgh programming, made for better coding, less stress, life is good. Programmers are people too! :D )
you'll kill 2 birds with one stone... they'll be able to tweak it better, and they'll also be able to play with the camera, and get the robot moving in the right direction. Optical encoders --> mecanum wheels scuff. Thats what they're designed to do, so be careful how you approach that. |

Our team made a demonstration holonomic drivetrain in the 2005 off-season, and our programmers drove that until we got the competition robot ready. Of course they still needed some time :rolleyes: to adapt to the actual robot's quirks. And of course they could have used more time than they got. These are the facts of life for software engineers: (1) you will be the last member of the design team to get your hands on the system, and (2) it will be your fault if it doesn't work. |

Re: pic: Mecanum Wheel Module Gearbox
Is this the same design featured in another thread? I know the colors on the cad are the same... and it looks like you even kept the suspention idea aswell! I'm interested to see how easely this works out for you.
And did I hear someone say that the CIM motors move slower or give less torque in one direction than the other? Um... a little enlightenment please? Thanks. |

For more than you probably wanted to know about how motor performance can depend on direction of rotation, read this thread.
