I just got the most recent issue of IEEE Robotics and Automation magazine, which has a theme of quadcopters as robotics research platforms. There is a large article describing the various attitude estimation and control algorithms used in Arducopter, OpenPilot, Paparazzi, Pikhawk, Mirokopter, KK muticopter, Multiwii, and Aeroquad. If you…
We've covered this before, but Hackaday has a good update on the latest ground-based power techniques:
The Google Earth blog reports:
An Inertial Measurement Unit is most often found in self-balancing robots and quadcopters, providing enough high-speed sensor data to keep up with the effects of gravity. He previously used some all-in-one IMU devices in…
You can't buy one, but you can back what seems like a very interesting project: to help build a vehcile that could set an autonomous sailing world record. Eighteen days to go and they're at $30,000 towards a $80,000 goal.
From the Kickstarter…Continue
Sounds like somebody neglected to research FAA rules before getting excited about putting an eye in the sky.

If you're buying a premade quadcopter kit like ArduCopter, it will come with a PCB-based Power Distribution Board. But what if you're making your own? You either have to wire together your own harness or, like xnaron did here, make your own PCB. He did a great job of it, but…Continue
From the Lawfare blog:
This excellent picture was forwarded to me by a colleague here at Brookings. It was shot by his friend,Bonnie Shaw, who tells me that she saw the flyer…
Lots of people have suggested 3D printing propellers, but Landru is the first I've seen to do it. Looks pretty good! (I'm not sure I'd trust my old Makerbot with this--he's got a better printer.) He writes:
This is a…
This picture is the last of the backlogged APM 2.5 orders going out from the 3DR shipping department. Orders should be shipped within 1-2 days from now on. Whew!
Demand was overwhelming but the 3DR team brought the second Tijuana pick-and-place line up with some state-of-the-art machines and it's finally running smoothly now. The line can now handle 500 APM 2.5 boards a week (in addition to its share of all the other 3DR products).
Another great hack from Hackaday:
This RC truck can be controlled with the tip of your thumb or the tilt of a wrist. That’s thanks to the IOIO which was inserted in place of the toy’s…
As is customary and traditional, we celebrate every new 1,000 members here and share the traffic stats. This time it's 29,000!…Continue
If you're using the Sharp IR sensor as an obstacle detector on your ArduRover, you should know that it doesn't see left and right equally. Here's some good analysis on its real detection pattern. So you might want to tilt the sensor a bit to the…Continue
This is an amazing price for a very capable multicopter flight controller board with GPS: just $65!
The MultiWii team has been using the ArduCopter code…Continue
At this point, you might be asking yourself, "Self, how can they possibly allow unlimited entries, quadcopters, and massive-scale robots at their current…
Watch it on the BBC's site here (embedding not enabled, sadly). Includes a bit about the troubles the West Wales Airport, which is hoping to become a drone center, is having finding tenants. Also includes an opera singer, who is worried about drones over her house, singing "Does it fall from the skies…Continue
The APM 1 board is still very popular, especially with fixed-wing pilots, but our world is moving to the smaller APM 2.x boards pretty quickly. So 3D Robotics is clearing their inventory of APM 1 boards with much lower prices.
The full APM 1 kit is now $100 off, …Continue
I'm not quite sure that they're right that this is the first autonomous transition from vertical to horizontal flight (there are some others that do that already, including Quadshot, although I suppose they could argue that it's more of a copter than a plane, or maybe not a full UAV?), but impressive all the…Continue
