[Whippet]

Well...

[Mike Starke]

Awesome job guys! Very well put together video as well!

Really 148 went with that collector.

Come now, we all know that in his time as Darth Vader he only used one lightsaber. I suggest one of the el toro arms be taken off.

Or rename it Darth Maul.

Very nice. It's always a treat to see the great production in your reveal videos.

I have to ask, how does the articulation for the strafing wheel work (I noticed the 2 strafing wheels but it looks like they are both not on the ground at the same time)?

I'd also love to here a bit more insight about the strafe wheels and how/why the articulate between multiple wheels

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

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.

Looking great guys!

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?
