Drone racing comes in different shapes and sizes, and some multirotor racers can be very small indeed. Racing means having gates to fly though, and here’s a clever DIY design by [Qgel] that uses a small 3D printed part and a segment of printer filament as the components for small-scale drone racing gates.
The base is 3D printed as a single piece and is not fussy about tolerances, meanwhile the gate itself is formed from a segment of printer filament. Size is easily adjusted, they disassemble readily, are cheap to produce, and take up very little space. In short, perfect …read more
Retiring to the garden for a few reflective puffs on the meerschaum and a quick shufti through the Racing Post, and the peace of the afternoon is shattered by the buzz of a drone in the old airspace,what! What’s a chap to do, let loose with both barrels of the finest birdshot from the trusty twelve-bore? Or build a missile battery cunningly concealed in a dovecote? The latter is what [secretbatcave] did to protect his little slice of England, and while we’re not sure of its efficacy we’re still pretty taken with it. After all, who wouldn’t want a …read more
Part of the charm of quadcopters is the challenge that building and flying them presents. In need of complex sensors and computational power to just get off the ground and under tremendous stresses thanks to their massively powerful motors, they often seem only barely controlled in flight. Despite these challenges, quadcopter flight has been reduced to practice in many ways, leaving hobbyists in search of another challenge.
[Tom Stanton] is scratching his creative itch with this radio-controlled tilt-rotor airplane that presents some unique problems and opportunities. Tilt-rotor planes are, as the name implies, able to swivel their propellors and transition …read more
It’s a known fact that the last mile is also the longest mile in the parcel delivery service. The further removed from a hub city a delivery location is, the more required stops in between. Every part of the process slows to a glacial pace when the drop-off spot is inaccessible by land or air. Now apply this in the case of a medical emergency, and timing is everything.
Enter the joint project between [DHL and Wingcopter] dubbed Parcelcopter 4.0. The half plane, half helicopter drone design was recently tested over a six month period by making medical supply drops …read more
We’ve always had a fascination with things that fly. Sure, drones are the latest incarnation of that, but there have been RC planes, kites, and all sorts of flying toys and gizmos even before manned flight was possible. Maybe the first model flying machine you had was a paper airplane. There’s some debate, but it appears the Chinese and Japanese made paper airplanes 2,000 years ago. Now there’s a database of paper airplane designs, some familiar and some very cool-looking ones we just might have to try.
If you folded the usual planes in school, you’ll find those here. But …read more
[Project Malaikat] is a 3D printed hybrid bipedal walker and quadcopter robot, but there’s much more to it than just sticking some props and a flight controller to a biped and calling it a day. Not only is it a custom design capable of a careful but deliberate two-legged gait, but the props are tucked away and deployed on command via some impressive-looking linkages that allow it to transform from walking mode to flying mode.
Creator [tang woonthai] has the 3D models available for download (.rar file) and the video descriptions on YouTube contain a bill of materials, but beyond …read more
Most civilized nations ban the use of landmines because they kill indiscriminately, and for years after they are planted. However, they are still used in many places around the world, and people are still left trying to find better ways to find and remove them. This group is looking at an interesting new approach: using ground-penetrating radar from a drone [PDF link]. The idea is that you send out a radio signal, which penetrates into the ground and bounces off any objects in there. By analyzing the reflected signal, so the theory goes, you can see objects underground. Of course, …read more
If you’ve spent an afternoon at the sticks of a remote-controlled aircraft, you’re probably well aware of the great limiter for such exploits: battery life. In the days when most RC aircraft were gas powered it was easy to cart along some extra fuel to keep the good times rolling, but now that everything except big scale models are using electric motors, RC pilots are looking for better ways to charge their batteries in the field.
Though it might seem counter-intuitive, [Adam Pyschny] is of the opinion that the best way to keep his quadcopter batteries charged is to simply …read more
The DelFly project has been busy since the last time we checked in on them. The Dutch team started 13 years ago and produced the smallest camera-carrying drone, and an autonomous tiny ornithopter. However, that ornithopter — now five years old — had to use some traditional control surfaces and a tail like an airplane which was decidedly not fruit fly-like. Now they’ve solved those problems and have announced the DelFly Nimble, a 13 inch and 1-ounce ornithopter. You can see the Nimble in the video below.
The close emulation of a real fly means the thing looks distinctly insect-like …read more
It seems kind of obvious when you think about it: why not just stick a solar panel on a quadcopter so it can fly on solar power? Unfortunately, physics is a cruel mistress, and it gets a bit more complex when you look at problems like weight to power ratios, panel efficiency, and similar tedious technical details. This group of National University of Singapore students has gone some way to overcome these technical issues, though: they just built a drone that is powered from solar power alone, with no batteries or other power source.
Their creation is a custom-built quadcopter …read more
