Robot that generates new actions

BeyondMimic, a structure that changes the rules of the game

For a long time, teaching robots to move like humans was an almost impossible challenge, they could walk, lift weight and repeat simple tasks, but always in a rigid, overly calculated way, without the natural fluidity that we have, but now, researchers at Cornell University presented BeyondMimic, a framework that changes the rules of the game by allowing humanoids to learn complex movements from human motion captures.

The demonstration video has already attracted attention, a humanoid robot performing runs, dance steps, spins, somersaults and even the famous celebration of the player Cristiano Ronaldo, and the most impressive thing is that none of it was pre-programmed, instead of rigid sequences, the system translates human data into a unified policy, capable of generating new actions even in test situations, that is, the robot does not just repeat, adapt and create variations in the movement.

At the core of this innovation is the use of Markov MDP decision processes and a set of hyper parameters that manage to handle multiple movements without manual adjustments, this eliminates the need for engineers to program each task separately, in minutes, the robot is already able to learn long consequences of human capture and then mix movements continuously, maintaining style, rhythm and even the original body expression.

It incorporates a technique that adjusts the robot's actions in real time.

Another key point is the so-called loss-guided diffusion, a technique that adjusts the robot's actions in real time based on custo functions, in practice it is as if it had an invisible guide correcting every detail to ensure that the movement is precise and stable, even when it tries something new.

This allows BeyondMimic to go from a martial arts kick to a dance spin, without losing balance, the impact is great because the system was developed as open source, allowing other researchers to replicate and advance the work, this accessibility accelerates real applications from rehabilitation and assistance theft to education, entertainment and social interactions.

A humanoid with expressive and adaptive movements is not only more convincing, but also more useful in everyday life contexts.
