Project Overview

This implementation case demonstrates advanced Physical Intelligence (PI) based sports robot technology realized through the quadruped robot ANYmal-D developed at ETH Zurich, Switzerland. ANYmal-D is a cognitive robot capable of engaging in actual badminton rallies with humans through reinforcement learning. It recognizes the trajectory of the shuttlecock using only on-board sensors without external sensors and performs agile plays by moving strategically using its entire body. This project is drawing attention as a practical demonstration of situational responsive automation technology, where robots judge and react independently in dynamic environments, going beyond simple automation.

Project Background & Objectives

Background

Conventional autonomous robots typically had limitations in performing repetitive tasks or following fixed trajectories in static environments. However, in unpredictable situations such as sports, advanced automation technology capable of real-time perception, judgment, and motion control is required. The research team at ETH Zurich pursued the ANYmal-D project with the goal of developing a robot system equipped with human-level athletic intelligence.

Objectives

• Implementing autonomous responsive motion control in unstructured environments

• Developing an integrated perception-motion system using on-board sensors

• Technical demonstration of sports-type robots capable of collaborating with humans

• Testing reinforcement learning algorithms based on Physical Intelligence (PI)
