Sounds more efficient than scratch engineering the item.

Why reinvent the windshield wiper?

[freebeard]

I can see that the cable drive allows the shafts to be not parallel, but those mill-finish aluminum wipers look to be about 8" long. Will you have segmented conformal arms of some sort?

Yes those wiper arms in the pic are way too short. I have not found the correct arms yet. I think large Class A RV arms may do the truck. I can buy blades up to 40" long, which sound about right.

I'm really looking forward to seeing this thing. If it performs even half as well as the Bullet Truck, it almost won't matter what it costs. You won't be able to build them fast enough.

Regarding wipers, I remember certain Mercedes models used (still do?) used a single arm design, but it had a cam sort of deal that made it extend/retract as it went around its sweep, so it would reach further into the corners. Or was that a cable drive design? My ignorance is presenting itself.

Thanks for the kind words on the current project. I can't wait to finish the thing.

That Mercedes used a cool mechanical design to do that in-out sweep. We need two wipers on a big truck per the feds.

It looks sexy! When are these things going to hit the roads? We need more fuel efficient trucks out there!
