In order to identify april tags, we used the `apriltag_ros` package which subscribes to the camera images and publishes the detected tags which each have a unique ID. The tags were used to locate the positions of objects in the scene as well as localize the camera frame from the robot's base frame. -## Robot Arm Control -The Franka Emika Panda Robot Arm has a ROS package `franka_ros` which allows us to control the robot arm using the Moveit API.
