A small team of roboticists at Robotic Systems Lab, ETH Zurich, in Switzerland, has designed, built and tested a four-legged robot capable of playing badminton with human players.

In their study, published in the journal Science Robotics, the group used a reinforcement learning-based controller to give the robot the ability to track, predict and respond to the movement of a shuttlecock in play, demonstrating the feasibility of using multi-legged robots in dynamic sports scenarios.

Badminton is a sport similar to tennis, the main difference being the use of a shuttlecock rather than a tennis ball. The goal is the same: to hit the shuttlecock over a net placed midcourt to an awaiting opponent.

While there are many potential uses for soft-bodied robots, the things are still typically only built in small experimental batches. Scottish scientists are out to change that, with a mass-production-capable soft bot that is 3D-printed in a single piece which then walks off of the print bed.

Before we go any further, this isn’t the first time we’ve heard about a soft robot that was printed in one piece.

It was just this March that we told you about a hexapod bot created at UC San Diego, which was 3D-printed in one continuous 58-hour step. That robot was powered not by a motor but by compressed air, which sequentially moves its legs forward.
