We investigate the shot-aiming problem in Pinball and design a model predictive controller to take shots toward targets with minimal trajectory error using a k-Nearest Neighbor regression-based flip function. A flip function maps the ball's state to its launch trajectory parameters. The k-Nearest Neighbor regression algorithm is applied to reduce the number of calibration shots required to estimate the flip function accurately. The controller is developed for a simulator built with Visual Pinball. The test results from this controller are compared to a controller built with a polynomial flip function. The experiments showed that the controller could accurately aim shots toward targets with minor trajectory errors after a few initialization shots.
