    7) Publication of the week - Two Years of Visual Odometry on the Mars Exploration Rovers (2006).
    https://onlinelibrary.wiley.com/doi/pdf/10.1002/rob.20184
    INFO: Did you know that Martian rovers Spirit and Opportunity had were equipped with 45 deg Field Of View (FOV) cameras producing 256x256 pixel stereo images for visual odometry providing a rover pose estimation in 6 degrees of freedom? According to the article the Visual Odometry started as an “extra credit” functionality but ended up being a critical safety system. In the first 10.7 km driven by the rovers the visual odometry was used for over 14% of navigation, mainly on steep terrain. The disadvantage that came with the visual odometry on those rovers is that it slowed down the robots by the order of magnitude, since the calculations were run on a 20 MHz CPU.
