OTTO is a robotic automatic motorized grinder and joint rolling machine

ROBOTS! They’re coming. Not much we can do about it. So why not have them roll us some joints??

That’s exactly what the folks at Banana Bros. must have been thinking when they invented this awesome weed gadget. It’s the OTTO Smart Grinder & Rolling Machine, the first ever all-in-one electric smart grinder and joint rolling machine.

Smart grinder uses sharp machined teeth to grind then, fills up with weed and rolls perfect joint cones

Touch a button and OTTO senses the consistency of its contents, automatically adjusts to perfectly grind your dry herb, then transforms it into a perfect cone in mere seconds. Just don’t make OTTO angry. That’s when the laser cannon boots up and zaps your neighborhood into a barren wasteland dystopia. (But honestly even if that happens, you’ll be puffin on the perfect robojoint, so it’s totally chill)

Advanced technology powers this smart grinder and rolling machine, allowing it to sense nugs and turn them into joints cones with precision

We found OTTO to be quite portable, making it quite travel-friendly for an automatic grinder & joint roller. With a USB port for easy charging and plenty of battery life, it can grind and pack 20-30 beautiful cones on a single charge. Of course in the future, autonomous electric smart-grinder robots will harvest their energy from the brainstems of human slaves. But for now, USB.

A cool transparent chamber lets you watch your joints get packed to perfection. It even comes with 20 all-natural premium cones to help get the party started. And in addition to black, the OTTO Grinder also comes in very cool Red and Gold versions.

The world’s first automatic smart-rolling machine grinds and packs 20-30 perfect cones on a single charge

Now despite any (well-founded) concerns you might have about OTTO becoming sentient and blood-thirsty, it really is a super awesome weed gadget. We love this thing. Just imagine dropping dry bud in the top and having a perfect joint pop out at the press of a button! Geeky weed dreams DO come true!!

And, uh, oh yeah....

  1. Can you please try to make a project that helps roll leaf’s and such instead of just cones?

  2. Hey, would you consider adding my grinder to your website? I would be happy to set up an affiliate type deal

    You don’t seem to have an email address listed anywhere, so I apologize if this isn’t the right place to leave the message.
