Complete-body coaching mannequin permits robots to imitate well-known athlete strikes
A workforce of AI and robotics researchers at Carnegie Mellon College, working with a pair of colleagues from know-how firm NVIDIA, has developed a brand new mannequin for coaching robots to maneuver like human athletes.
Of their paper posted on the arXiv preprint server, the group describes how they developed the brand new method to permit for coaching full-body athletic actions with humanoid robots, and the way nicely the method has labored so far.
Of their new effort, the analysis workforce famous that the majority efforts to coach robots to do issues middle primarily round locomotion. The outcome has been the event of a bunch of robots which might be capable of get round very nicely. However none of them, the workforce notes, do it with a lot grace; they lack fluidity or athleticism—hallmarks of pure animal actions. The reply, they believed, was to shift the main focus to utilizing whole-body coaching.
In seeking to develop whole-body coaching, the workforce discovered that present coaching fashions lacked adaptability and sometimes used too many parameters, leading to overly cautious actions. That led them to develop a brand new two-stage mannequin, or framework as they name it.
The primary stage includes coaching an AI module to know whole-body human movement movies—with the salient factors retargeted to contemplate robotic capabilities along side movement monitoring. The second stage includes amassing real-world knowledge to establish and reconcile variations between actions in the actual world (the way in which folks transfer within the movies) and the way robots can transfer. The result’s a framework the workforce calls Aligning Simulation and Actual Physics (ASAP).
To check the brand new framework, the researchers skilled a robotic to make strikes acquainted to sports activities followers. The robotic carried out Kobe Bryant's well-known fadeaway soar shot, LeBron James' Silencer transfer and Cristiano Ronaldo's Siu leap with a mid-air spin. Every whole-body ability was recorded because it was carried out, and the outcomes had been posted to YouTube.
Watching them, it’s simple to acknowledge the well-known strikes and be aware the progress made in bettering full-body movement. However it’s also simple to see that rather more work must be carried out earlier than a robotic will ever be mistaken for an expert human athlete.
![Retargeting Human Video Motions to Robot Motions: (a) Human motions are captured from video. (b) Using TRAM [93], 3D human motion is reconstructed in the SMPL parameter format. (c) A reinforcement learning (RL) policy is trained in simulation to track the SMPL motion. (d) The learned SMPL motion is retargeted to the Unitree G1 humanoid robot in simulation. (e) The trained RL policy is deployed on the real robot, executing the final motion in the physical world. This pipeline ensures the retargeted motions remain physically feasible and suitable for real-world deployment. Credit: arXiv (2025).
