Columbia University engineers build robot that ‘learns to imagine itself’

Columbia Engineers build a robot that learns to understand itself, rather than the world around it

As every athletic or fashion-conscious person knows, our body image is not always accurate or realistic, but it’s an important piece of information that determines how we function in the world. 

When you get dressed or play ball, your brain is constantly planning ahead so that you can move your body without bumping, tripping, or falling over.

We humans acquire our body-model as infants, and robots are following suit. A Columbia Engineering team has created a robot that – for the first time – is able to learn a model of its entire body from scratch, without any human assistance. (See video below.)

Engineers at Columbia University invent robotic lasers that cook food

by Leave a Comment

Engineers at Columbia University have invented software-controlled robotic lasers that cook food with “unparalleled precision”, retaining more moisture, and creating an entirely new, customized way to cook a tasty meal. (See videos below.)

Imagine having your own digital personal chef; ready to cook up whatever you want; able to tailor the shape, texture, and flavor just for you; and it’s all at the push of a button. Columbia engineers have been working on doing just that, using lasers for cooking and 3D printing technology for assembling foods.

Under the guidance of Mechanical Engineering Professor Hod Lipson, the “Digital Food” team of his Creative Machines Lab has been building a fully autonomous digital personal chef. Lipson’s group has been developing 3D-printed foods since 2007. Since then, food printing has progressed to multi-ingredient prints and has been explored by researchers and a few commercial companies.

The robot smiles back: Columbia scientists teach robot how to respond to human facial expressions

by Leave a Comment

Columbia Engineering researchers use AI to teach robots to make appropriate reactive human facial expressions, an ability that could build trust between humans and their robotic co-workers and care-givers. (See video below.)

While our facial expressions play a huge role in building trust, most robots still sport the blank and static visage of a professional poker player.

With the increasing use of robots in locations where robots and humans need to work closely together, from nursing homes to warehouses and factories, the need for a more responsive, facially realistic robot is growing more urgent.

Deep learning networks prefer the human voice – just like we do

by Leave a Comment

Columbia engineers demonstrate that AI systems might reach higher performance if programmed with sound files of human language rather than with binary data labels. (See video below.)

The digital revolution is built on a foundation of invisible 1s and 0s called bits.

As decades pass, and more and more of the world’s information and knowledge morph into streams of 1s and 0s, the notion that computers prefer to “speak” in binary numbers is rarely questioned.

According to new research from Columbia Engineering, this could be about to change. [Read more…] about Deep learning networks prefer the human voice – just like we do
