Pop’em Drop’em Robots

Abstract

Our project is an electronic version of the game “Rock’em Sock’em Robots”. Up to two players can play, each controlling the movements of one of two punching robots via a Microsoft Kinect. Player punches and dodges are translated into robot movements and hits recorded until either player’s health bar value reaches zero. The game also features selectable battle music and a single-player mode in which the player competes against the computer.
