I believe it's approx. .8lbs for each mounting block, which brings the weight of each module up to a whopping 4 pounds. Woo.

No matter how you slice it, .8 pounds is a lot. Also, you are cantilevering the module mount (I'm not talking about not supporting the module on top on bottom, but rather only from one side). It would be much more efficient to support the module from two sides. This would require a frame change, but you can switch a lot of the 2x1 to 1x1 in the process along with changing the inner rails to thin wall.

Re: Leaked Footage...

This crab was completely designed by Ninjaneering's Craig Hickman. Although it may contain some similarities and influence from from previous Robonauts crabs it is not one of them, this is pure Ninjaneering! Take this as a 'teaser' or something as you will make of, for next year... Enjoy!

Re: Leaked Footage...

yea i was like: "wait a second, i recognize those wheels! i smell a trick" i love these pratical jokes of desighn geeky ness. anyone notice that they always have to do with crab drive? (the 254/968 swerve fiasco)

really sweet design, proven and verry agile. isolating the steering and drive of the individal modules really allows for some really cool capabilities. think, if done right, you could spin with zero turning radius, AND still have the capabilities of crab drive, without having to make a turreted manipulator.

incredible, but i dont know why the sides are angled, it would seem flat sides would interface with bumper mounts better, and provide a simpler frame to work with, not limiting the space available inside your chassis IMO.

Re: Leaked Footage...

Neat concept, but I also think those module-mounts are a bad way to do it (Not trying to put your design down, that's just not how I would do it. It would probably work great your way, but I always try to avoid designs with high-load carrying parts)

The overall trapezoid-like design of the frame is awesome! It supports what it needs to and makes it easy to get inside of the robot. Bonus points for looks, too! I really hope someone builds this, it would be way cool to see it driving around.

I can't ague with this; a long time ago I did pester Bill a lot during the build season. :cool:

Re: Leaked Footage...

There needs to be a lot more chains for it to be a 118 machine... Looks good.
