There are probably a lot of things that fit that description, but the one that [Nick Rehm] is working on is known as an ekranoplan. Specifically, he's looking to make <a href="https://www.youtube.com/watch?v=uaY2G5Kbj_g" rel="nofollow noopener" target="_blank">the surface-skimming ground-effect vehicle operate autonomously</a>. If you think you've heard about ekranoplans around here before, you'd be right -- we've covered <a href="https://hackaday.com/2021/04/29/rc-ekranoplan-uses-lidar-to-fly-in-ground-effect/" rel="nofollow noopener" target="_blank">a cool LIDAR-controlled model ekranoplan</a> that [rctestflight] worked on about a year ago, and more recently, [ThinkFlight]'s attempts to make <a href="https://hackaday.com/2021/10/10/autonomous-ground-effect-vehicle-demonstrator-aims-to-speed-up-maritime-shipping/" rel="nofollow noopener" target="_blank">an autonomous ekranoplan</a> that can follow behind a boat. The latter is where [Nick] enters the collaboration, and the featherweight foam ground-effect vehicle shown in the video below is his test platform. After sorting out the basic airframe design and getting the LIDAR integrated, he turned his attention to the autonomous bit, which relies on a Raspberry Pi 4 running ROS and a camera with a wide-angle lens. The Pi uses machine vision algorithms to find an "AprilTag" fiducial marker in the scene, which gives the flight controller information about the relative orientation of the ekranoplan to the tag. [Nick] tested tag tracking using an electric longboard, and the model ekranoplan did an admirable job of not only managing the ground-effect, but also staying on target right behind him. And hats off to [Nick] for keeping all the balls in the air and not breaking his neck in the process. We're looking forward to seeing what [Nick] built here end up in [ThinkFlight]'s big ekranoplan build. Ground-effect vehicles like these are undeniably cool, and it seems like they've got the potential to solve some interesting transportation problems. <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/dronehacks/" rel="nofollow noopener" target="_blank">#dronehacks</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/apriltag/" rel="nofollow noopener" target="_blank">#apriltag</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/ekranoplan/" rel="nofollow noopener" target="_blank">#ekranoplan</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/fiducial/" rel="nofollow noopener" target="_blank">#fiducial</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/gev/" rel="nofollow noopener" target="_blank">#gev</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/groundeffect/" rel="nofollow noopener" target="_blank">#groundeffect</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/machinevision/" rel="nofollow noopener" target="_blank">#machinevision</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/raspberrypi/" rel="nofollow noopener" target="_blank">#raspberrypi</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/ros/" rel="nofollow noopener" target="_blank">#ros</a>

hackaday unofficial<a href="https://hackaday.com/2021/10/10/autonomous-ground-effect-vehicle-demonstrator-aims-to-speed-up-maritime-shipping/" rel="nofollow noopener" target="_blank">Autonomous Ground Effect Vehicle Demonstrator Aims To Speed Up Maritime Shipping</a> Ground effect vehicles, or ekranoplans, have the advantage of being more efficient than normal aircraft and faster than boats, but so far haven't been developed beyond experimental prototypes. Fortunately, this doesn't stop companies from trying, which has led to a collaboration between [ThinkFlight] and [rctestflight] to create a <a href="https://www.youtube.com/watch?v=S-eND8-AZFI" rel="nofollow noopener" target="_blank">small-scale demonstrator</a> for the <a href="https://flyingship.co/" rel="nofollow noopener" target="_blank">Flying Ship Company</a>. The Flying Ship Company wants to use unmanned electric ekranoplans as high-speed marine cargo carriers that can use existing maritime infrastructure for loading and unloading. For the scale model, [rctestflight] was responsible for the electronics and software, while [ThinkFlight] built the airframe. As with his <a href="https://hackaday.com/2021/05/24/ground-effect-drone-flies-autonomously/" rel="nofollow noopener" target="_blank">previous ekranoplan build</a>, [ThinkFlight] designed it in XFLR5, cut the parts from foam using a CNC hot wire cutter (which we still want a better look at), and <a href="https://www.youtube.com/watch?v=_jJKR8cdHO0" rel="nofollow noopener" target="_blank">laminated it with Kevlar</a> for strength. One of the challenges of ground effect vehicles is that the center of pressure will shift rearward as they leave a ground effect, causing them to pitch up. To maintain control when moving into and out of ground effect, these crafts often use a large vertical stabilizer high up on the tail, out of ground effect. A major feature of this demonstrator is automatic altitude control using a LIDAR sensor mounted on the bottom. This was developed by [rctestflight] using a [simple foam board ekranoplan](<a href="https://hackaday.com/2021/04/29/rc-ekranoplan-uses-lidar-to-fly-in-ground-effect/" rel="nofollow noopener" target="_blank">https://hackaday.com/2021/04/29/rc-ekranoplan-uses-lidar-to-fly-in-ground-effect/</a><a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/more-474188/" rel="nofollow noopener" target="_blank">#more-474188</a>) and <a href="https://www.youtube.com/watch?v=3heh9swH2Zw&t=12s" rel="nofollow noopener" target="_blank">[Think Flighs]'s previous airframe</a>, with some custom code added to ArduPilot. It works very well on smooth, calm water, but waves introduce a lot of noise into the LIDAR data. It looks like they were able to overcome this challenge, and completed several successful test flights in calm and rough conditions. The final product looks good, flies smoothly, and is easy to control since the pilot doesn't need to worry about pitch or throttle control. It remains to be seen if The Flying Boat will overcome the challenges required to turn it into a successful commercial craft, and we will be following the project closely. <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/transportationhacks/" rel="nofollow noopener" target="_blank">#transportationhacks</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/ardupilot/" rel="nofollow noopener" target="_blank">#ardupilot</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/ekranoplan/" rel="nofollow noopener" target="_blank">#ekranoplan</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/groundeffect/" rel="nofollow noopener" target="_blank">#groundeffect</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/lidar/" rel="nofollow noopener" target="_blank">#lidar</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/rctestflight/" rel="nofollow noopener" target="_blank">#rctestflight</a> <a class="mention hashtag" href="https://xn--y9azesw6bu.xn--y9a3aq/streams/tag/thinkflight/" rel="nofollow noopener" target="_blank">#thinkflight</a>

hackaday unofficial<a href="https://hackaday.com/2021/04/29/rc-ekranoplan-uses-lidar-to-fly-in-ground-effect/" rel="nofollow noopener" target="_blank">RC Ekranoplan Uses LIDAR to Fly In Ground Effect</a> Ekranoplans are a curious class of vehicle; most well known for several Soviet craft designed to operate at sea, flying just above the waves in ground effect. [rctestflight] had accidentally come across the ground effect flight regime himself years ago, <a href="https://www.youtube.com/watch?v=nvMUYdr5_g8" rel="nofollow noopener" target="_blank">and decided it was time to build an ekranoplan of his own.</a> I want to see little ekranoplans in at least three top 10 pop film clips by summer's end. Please and thank you. While ground-effect flight can be quite stable for a heavy, human-scale craft, the smaller RC version suffered more from minor perturbations from the wind and such. Thus, a Pixracer autopilot was installed, and combined with a small LIDAR device to accurately measure altitude above the ground. With some custom tweaks to the Ardupilot firmware, the craft was able to cleanly fly along barely a foot off the ground. The final effect is almost mesmerizing; it appears as if the craft is hovering via some heretofore unknown technology rather than just flying in the usual sense. It's still sensitive to breezes and sudden drops in the terrain lead to a temporary escape from the ground effect region, but the effect is nonetheless impressive. It's a nerve wracking video at times, though, with quite a few near misses with traffic and children. Regardless of the nature of your experimental craft, be cognisant of your surroundings. <a href="https://hackaday.com/2019/08/18/ardurover-boat-uses-to-float/" rel="nofollow noopener" target="_blank">We've seen [rctestflight]'s Ardupilot experiments before, too</a>.
