Evaluating the performance of the robotic system through comparison with human trackers. Evaluating the performance of the robotic system through comparison with human trackers. We performed two flights at each of four trial sites (eight flights in total). The box plot illustrates the estimate errors (on the y axis) for both the robot (green and blue) and the human (white and gray) trackers as a function of the observation number (on the x axis). The blue boxes labeled “Robot (certain)” indicate scenarios where the bird remained stationary during the trial and the final location was known. Oliver M. Cliff et al. Sci.
