HITTER: A HumanoId Table Tennis Robot via Hierarchical Planning and Learning
Overview
Paper Summary
Researchers developed a humanoid robot capable of playing table tennis using a combination of motion capture, planning algorithms, and learned control policies. While the robot successfully rallies with humans and other robots, its performance is limited by the need for motion capture and a simplified stroke set. It also struggles with short or deep shots due to a fixed hitting plane.
Explain Like I'm Five
Researchers built a robot that can play table tennis! It uses cameras to see the ball and a computer program to plan its moves, hitting the ball back and forth like a human.

Identified Limitations
Rating Explanation
This paper presents a well-executed robotics project with impressive real-world results. The hierarchical control system and integration of model-based planning with reinforcement learning are notable strengths. However, the dependence on external motion capture and limitations in stroke repertoire prevent a higher rating.
