That shot at the end. I know that's going to be even more popular now.

Me too, especially with the mecanum wheels at 5 seconds.

That play in general will be a lot more powerful than people were thinking at the beginning of the year. If you have a human player that is used to it, you can get easy truss points and you won't lose control of the ball.

Parts of Texas are in the area of the country known as "Tornado Alley." As for Raptor I think when they released it they said the name was a reference to the predatory birds, not the dinosaurs, also a feature in Texas.

Plus I believe in the past they've said their robot names have followed a Texas theme, but I may be imagining that.

Those mecanum wheels are on a drive in a day frame, and I am pretty sure the final robot had omni wheels. Also, I think their frame has 6 sides unlike the one they had mecanum wheels on.

Yeah, I believe you are correct. I'd be very interesting to hear from 148 about how this drive differs from their 2010, prior butterflies and a straight up mecanum and why they picked it.

Ah, well this clears it up... :rolleyes:

It looks like the axle that the little two-wheel fork is on is also the axle through which the wheels are powered. As a result when the motors spin the fork rotates until it hits the ground. Once the fork can't go further down the wheels are forced to rotate by the same motor. If that is the case its a pretty cool system.

Off to watch the video some more..

I am thinking the same thing, but I am having issues see how they are getting enough force to give the wheel traction because won't most the weight still be on the 4 outer wheels?

I noticed a rangefinder on the front of the bot. Could that be an autocatch feature?

This is awesome. I appreciate the early post. The subtle changes over the "BoomDone" robot are awesome and are clearly well thought out. Good luck this year!
