[Bears]

Hey there guys, about a year ago we posted a video on our Omni Drivetrain. We have just released a guide on how to make it with all the files included, check it out!

nice vid guys, it's really great and i am really happy that you guys including everthing down to the coding not sparing a thing

though mechanum is the way to go

La Canada Engineering Club's ftc team had a set of mechanums 3D printed if you need more info on mechanum drive there defiantly some info floating around on cd

Woah... I thought this was FRC and almost died. In fact, maybe I did. Please never use omni ever in FRC.

Care to explain why? I've seen some dominant omni wheel-using FRC robots (1501 in 2010 springs quickly to mind), and lots of very effective 4wd, 6wd or 8wd drivetrains use omnis.

We used Omni in 2011 and were finalist at Lone Star.

It has been done in FRC before and been pretty successful.

Amazing video guys!! I see you also do VEX along with FTC. Are you using this same drive for VEX?

We personally have no experience in FRC so we wouldn't know :P (but I imagine it works as good as it does in FTC). We do also compete in VEX (we are team 4131, you can see us at the World Championship), and we didn't opt to use OMNIs there, we actually use Mecanum. We are happy you liked it,

Greetings

Congrats!! We look forward to seeing you at Championships. Come check us out VEX 2587) in the pits. I believe we'll have 3 teams there.

You can be sure we'll visit your pit (hope you can check ours too :P ),

We are really happy you liked it. We in fact know about Mechanum wheels, but as they are not officially out for the Tetrix platform, this has been our alternative for the past few seasons, well see about building ones for next season,

Please leave the omni hating for another thread.

Thanks a lot, we are here to help!

We agree, and we believe OMNI wheels are a great alternative (specially in FTC) to Mecanum wheels, as this are inexistent in the Tetrix platform

Omni wheels and omni drives are highly effective in FTC. Because of the restrictions on motors and fabrication, it's very hard to make a drivetrain that's very effective. i did see a swerve drive at a qualifier i went to, but the operators were not comfortable driving it. Props to getting an omni system built and programmed.

Nice build, love the high speed build cycle.

A change you might want to think about is adding support on both sides of the wheel. The current cantilever of the wheel stresses the motor bearings. With these out in the open there is the chance of high speed impact breaking the motor.

You are absolutely right, we will try to implement support on the outside side of the wheels on the next version of the chassis. We are glad you liked it!

Yes, OMNI Drives have been quite effective for us, but they do require A LOT of practice (like anything) from the drivers. Thanks a lot, we are glad you liked it
