What this video represents and means is very important. We are in front of the first robot that learns to walk without any external help. Without external help or software that tells it ‘what it is to walk’. This is an extreme achievement in the field of artificial intelligence and robotics specifically in the territory of deep learning.
The deep or reinforced learning algorithms, which allow robots to learn movements by trial and error, still depend on human intervention. Every time a robot falls or leaves its training environment, you need someone to pick it up and put it back in the right position, but this Google project has achieved a major breakthrough to robots able to learn to move by themselves
In just a few hours, and exclusively from adjustments of the latest and most advanced algorithms, they managed to make a four-legged robot learn to walk backwards and forwards, and to turn left and right, all by itself.
