what robotic leg technologies are available.
i'm sorry if this is a basic question i am a software developer looking to get into the field of robotics. i am particularly interested in robotic legs that are similar to those used on Boston Dynamics ATLAS robot.
what is the mechanism required that allows it to move its joints so quickly. if you see any videos of many of Boston Dynamics robots they make an engine sound (presumably because it uses an engine), but i cant find any details in the configuration that is being used.
