After our previous video showing how Pepper the Robot learns to play the ball-in-a-cup game (https://www.youtube.com/watch?v=jkaRO8J_1XI), realized by the AI Lab of SoftBank Robotics, here we see how Pepper learns to play Velcro Darts in the same way.
The movement is first demonstrated to the robot by guiding its arm. From there, Pepper has to improve its performance through trial-and-error learning. Even though the initial demonstration does not hit the center of the dartboard, Pepper can still learn to play the game successfully.
After 60 trials, Pepper scores 100 points, most of the times!
The movement is represented as a so-called dynamic movement primitive and optimized using an evolutionary algorithm. Our implementation uses the freely available software library dmpbbo: https://github.com/stulp/dmpbbo.")

After 100 trials, Pepper has successfully optimized its behavior and is able to repeatedly land the ball in the cup.")
