GE 423 Final Project

Ben Speidel, Zoe McCarthy

We used the Cartesian coordinate robot locating software along with the camera to map the location of a green ball onto the same xy coordinate frame. Through the collection of reference points, the pixel coordinates of the green object centroid can be converted into a location relative to the robot. This can then be used to calculate the ball’s actual coordinates. The Robot can then record the ball’s location as it moves and then replicate its trajectory. The screenshot to the left shows a Visual Basic program that displays the robot’s location as a hollow circle and the ball’s location as the filled in circle. Below is a picture of the ball and robot that we used.
