Acrobots

Modern robots like Boston Dynamics' Atlas use similar principles of momentum and balance to perform flips and navigate rough terrain.

Whether it's a digital model in a physics simulator or a physical machine in a robotics lab, the Acrobot continues to be a vital tool for teaching machines how to move with the grace and intelligence of a human performer. Dynamics Showing Perfection in Acrobats- Robots by Boston Acrobots

The robot must learn to oscillate back and forth, increasing its arc until it has enough speed to reach the top. Modern robots like Boston Dynamics' Atlas use similar

Because the first joint has no motor, the robot is . It cannot simply "lift" itself; it must use precisely timed "kicks" at the elbow to build up energy, eventually swinging into an inverted vertical position—a feat known as the "swing-up" task. The Challenge of Control Because the first joint has no motor, the robot is
