Let's have a general understanding of this black technology of Boston Dynamics in the United States: on the surface, it shows that robots can dance, but secretly, it shows the coordination between robots (they will not collide with each other) and machine learning ability, which requires high AI/ machine learning algorithms. As we all know, Boston Dynamics is a private enterprise separated from the famous Massachusetts Institute of Technology, which shows that it is full of talents. It's really more than enough for us to discuss among ordinary people. But if we don't appreciate what we invented, it will waste the brains of people with high IQ. Isn't that the difficulty of this technology? Let's see: According to public reports, Atlas, as a hydraulically driven robot, is 1.5m high and weighs 80kg. There are 28 joints in the whole body, 6 degrees of freedom in one leg, 2 degrees of freedom in the waist and 7 degrees of freedom in the arm, all of which are driven by hydraulic pressure. The most difficult part of Atlas hardware system is the hydraulic power system. Using more complicated hydraulic system, the deepest reason is that the motor still can't drive the 180-pound robot to complete the walking task, which is remarkable. The efficiency is much higher than that of the previous hydraulic quadruped robot, which makes Atlas obtain higher energy conversion efficiency at the driving level. Up to now, most robots use motor systems.
Judging from the explosive movements of Atlas such as parkour, backflip and word horse in the past, the driving force of Atlas is very explosive, but today we see such beautiful and soft dance movements, and the lines are soft enough to make people look close to human limbs. It shows great progress. This is enough to subvert our previous view of robots. With the development of science and technology, the skills of robots are getting closer to people, so it is necessary to cultivate emotional intelligence and anti-frustration ability quickly!
