Launch file added that starts Baxter's left camera, listen to QR code position, performs OpenCV to publish position of center of object, and moves Baxter according to a PoseStamped() message.
Added new node that listens to a topic accepting PoseStamped() messages, and moves towards it if a solution is possible.
Added a new node that only listens to the position of object from OpenCV and publishes a message each time to get closer to the object.
Added a new node that listens to QR code position and sends a PoseStamped() message to move towards it.
Should be not used anymore, is being replaced by different nodes. Keeping for reference.
Node accepts listens to a topic in order to determine which color should be thresholded against.
Node has been separated into three different nodes such that each only is responsible for doing one thing. Should not be used anymore.
