Looks like the colsons dig in when they get pushed, using the drop center tilt rather than an active piston to actuate the "butterfly" mechanism.

Never seen that before (I don't have much experience with drivetrains) but looks very ingenious and effective.
Their system is set up like 33 had their drive in 2011. http://www.chiefdelphi.com/media/papers/2515
I can see that being insanely light.

I thought those pistons were for some sort of intake.... whoa.
Looks like 624 just one-upped butterfly/octocanum drive :eek:

Now the question is, are they doing the auto shift thing like 33 did?
Also, I know of at least one octocanum that uses a similar mechanism, but instead has two extra small modules in the center ;) .

Yes this is a 5 wheel omni drive in one mode and a conventional tank with colsons in the other mode. Transitioning between mode is by shifting the front colsons down lifting the omni wheels off the ground. This entire drivetrain can be built using COTS parts and simple tools (drill press and band saw). The center omni is biased down by 1/8". Will see how it holds up.

Nice robot -- I really like the drive & your high catapult. The lighting is a bonus, and it really looks sharp. Also, whomever did the video deserves a pat on the back.

Now, I have to ask -- how did you attach the camera to the ball at the end of the video?

We put it in the protective case then...a lot of duct tape.

Very elegant solution! Probably the simplest way to get both high mobility and pushing power.

+1

They really need to do one.....between 118, 148, 624, 1477, 2468, and 3847, Texas is stacked

With some of the other teams coming (359), we will be spending a lot of time studying in the pit area.

As well as 2415, 3310, and several other Dallas powerhouses that I'm not familiar with.

Just saw the reveal video for 2587.....you guys also have a good machine...

Spectrum, Cryponite, and you guys all went with good DT's for this game...the ability to switch between defense and maneuverability will be very helpful.

Thank you, our goal was to come up with a new idea by mixing ideas that have been used before. We are excited to see how it plays out at events and hope that teams might adopt the idea in the future since it uses all COTS items and can be manufactured without extremely expensive machinery that some teams may not have access to

Did you guys use Versachassis or just stock tubing?

Shhhhhh don't jinx it!

Great looking robot. Too bad we don't play with you guys this year. Maybe at champs or definitely at TRR this year.

NOW that is what I call a quality reveal. The maker of this video really deserves some credit. 624, a well known team, has once again made a product of exceptional quality. Alamo, Orlando, and Lone Star, Watch out!::safety::
