To be beaten by a robot is no fun! Will we have to ban robots from competing with humans in sports?
What is the future of sports and the Olympic Games! Develop a more competitive robot?
"... The robot so adept it can even maintain rallies up to 10 consecutive shots.
And an even bigger surprise – the robot learns from its errors.
They say their robot demonstrates “the feasibility of using legged mobile manipulators in complex and dynamic sports scenarios.
“Beyond badminton, the method offers a template for deploying legged manipulators in other dynamic tasks where accurate sensing and rapid, whole-body responses are both critical,” ..."
From the abstract:
"Coordinating the motion between lower and upper limbs and aligning limb control with perception are substantial challenges in robotics, particularly in dynamic environments.
To this end, we introduce an approach for enabling legged mobile manipulators to play badminton, a task that requires precise coordination of perception, locomotion, and arm swinging. We propose a unified reinforcement learning–based control policy for whole-body visuomotor skills involving all degrees of freedom to achieve effective shuttlecock tracking and striking.
This policy is informed by a perception noise model that uses real-world camera data, allowing for consistent perception error levels between simulation and deployment and encouraging learned active perception behaviors.
Our method includes a shuttlecock prediction model and constrained reinforcement learning for robust motion control to enhance deployment readiness.
Extensive experimental results in a variety of environments validate the robot’s capability to predict shuttlecock trajectories, navigate the service area effectively, and execute precise strikes against human players, demonstrating the feasibility of using legged mobile manipulators in complex and dynamic sports scenarios."
