Robotic dexterity using…coffee?

One of the biggest obstacle within the realm of robotics is how to grip things. Sure, if your robot is placed at an assembly line where all the pieces are the same shape, it may be simple. But what if you want your robotic hand to be able to grip any shape? What was a seemingly impossible request before is now so easy, you can make it at home! All you need is a party balloon, ground coffee and a vacuum pump, and your robotic gripper can lift almost anything. And if you add a pressure pump, it can even throw things!If you don’t believe us then just watch this fantastic video from Cornell Creative Machines Lab! Isn’t it amazing how the simplest of materials, combined just right, can solve the most difficult of problems?

 

How to make Chocolate bowls

#craftersu #diy #Chocolate

This is a very interesting video from the Japanese YouTube channel Hey! It’s Mosogourmet! In this speechless video, you can learn how to make neat bowls out of chocolate and fill them with any other foods, like ice cream. We wouldn’t recommend hot food items though, since it would probably melt the bowl. In any case, this can be a very appreciated way of presenting your food at a party, so we strongly recommend anyone who like to entertain to watch this video. Unfortunately it does not contain the necessary information about how to melt and temper chocolate, so we added another video from  the unrelated YouTube channel Howdini where the world-renowned chocolate maker Jacques Torres shows us how to melt and temper chocolate. In the video below he shows us both the simple microwave solution, and the professional techniques, so you can choose what level of seriousness you want to apply to your presentation.
