The demonstrators were: Wing Circulation Control: taking air from the aircraft engine and blowing it supersonically through narrow slots around a specially shaped wing tailing edge in order to control the aircraft and Fluidic Thrust Vectoring: controlling the aircraft by blowing air jets inside the nozzle to deflect the exhaust jet and generate a control force.

    4) Seven Dreamers / Anki closes down.
    The Robot Report/IEEE
    INFO: The past week has been filled with bad news for those waiting for a rise of consumer robots. Seven Dreamers, a company working on the Laundroid laundry-folding robot close down. We were very surprised to learn that Anki (which we mentioned when we showcased vector_ros project one week ago) is also closing down due to failing to secure a new round of financing. The linked IEEE article raises a good point on what happens to customer’s robots if the cloud servers go down. This guest article by Guy Hoffman is an interesting analysis of failed social robot startups.

    7) Publication of the week - Pseudo-LiDAR from Visual Depth Estimation:Bridging the Gap in 3D Object Detection for Autonomous Driving (2019).
    arXiv
    INFO: We found the above paper cited in several articles ([1], [2]) that surfaced after Elon Musk made a statement about LiDARs being a fool’s errand during Tesla autonomy days earlier this week. We’ve decided to see ourselves what the paper says and if stereo cameras will beat LiDARs any time soon. The paper has been written by Cornell University Researchers. In the paper they propose an alternative method for representation of 3D information obtained from stereo cameras so that it resembles LiDAR data (pseudo-LiDAR) and therefore LiDAR based object detection algorithms can be applied to it. The experiment setup is based on the KITTI benchmark and there are two algorithms that Researchers evaluate: F-POINTNET-v1 and AVOD-FPN. Looking at the results table the chosen approach is a significant improvement over other camera based methods however at high Intersection over Union there is still a high gap between stereo based method described and Lidar + monocular camera based method. In case of Bird Eye View representation with AVOD algorithms and the IoU of 0.7 the researchers obtained a result of 74.9 (89.4 for LiDAR + mono camera) in Easy category and 49.0 (79.3 for LiDAR + mono camera) in Hard category.

The system is using biomimetic sonar sensor that perform echolocation and a Hokuyo laser rangefinder that is used for capturing the ground truth information. To create a BatSLAM solution the Researchers process the information from the sonar sensor to create 8-bit images that they later use with RatSLAM. The end goal for the researchers is to use this solution to create an autonomous wheelchair.
