摘要：In this research, a two dimensional Cartesian robot is
designed and built that is applied as a robotic air hockey table.
An air hockey disc is put into play, the machine can attempt to
score against the opponent and defend against subsequent
attempts to score on the robot’s goal. An Arduino compatible
vision system is designed to track the direction of the puck and
extrapolate its movement by using two successive points of
reference. This extrapolated movement is the basis of the robot’s
movement. Once the trajectory is found, three DC stepper
motors are used to control the end effector of the robot, using a
belt driven system. The end effector can be positioned to a point
that intersects with the disc’s trajectory in order to successfully
defend the goal.
