    7) Publication of the week - The Foldable Drone: A Morphing Quadrotor that can Squeeze and Fly (2018).
    Robotics and Perception Group
    INFO: This project by researchers from Robotics and Perception Group from University of Zurich gathered quite some attention lately (1 2). The quadrocopter described in the paper is based on the Qualcomm Snapdragon Flight flight controller. The motor frame described in this paper has each of the arms mounted on a servo motor (HiTech HS-5070MH) and offset vertically so that adjacent propellers do not collide. Folding the arms on the quadrotor impacts CoG (Center of Gravity) location, inertial tensor of the platform and thrust mapping. The multirotor can sustain a stable flight thanks to real-time adaptive control scheme. We highly recommend watching the videos linked in the paper and a radar diagram showing how different configurations affect pitch/roll acceleration, flight time and robot’s dimensions.

    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.
