Abstract: An interactive laboratory robotic system is described that includes devices for use in a laboratory including a robotic assistant that can perform tasks and that can be controlled and configured by humans. The robot may assist personnel in performing repetitive tasks within a laboratory, and capture and store transactional and analytical data, such as during a DNA sequencing process. The robot may include sensors and/or cameras to detect, recognize, and track objects in an environment, and a manipulable arm having a hand for grasping objects. Other components of the system may include a sample tray graspable by the robot; a tray carriage for holding sample trays within equipment; an interactive shelf for holding sample trays; a mobile cart for mating with and charging the robot; and an accessory unit to enable the robot to open doors of equipment. The system may help to reduce or eliminate mistakes by personnel.
