Kenn Sebesta commented on Chris Anderson's blog post Ground robot tracks and controls air robot
"@Martin--  I'd give them a bit more credit. UZH is across the street from ETHZ, and there's a lot of cross-pollination that goes on. In addition, Davide Scaramuzza is a rising star in the robotics vision world so my ears always…"

Kenn Sebesta commented on Greg Dronsky's blog post Drone outlook: The next 5 years
"Gary-- Full disclosure, I left BU to go work at CyPhy Works. My comments might be biased. ;) What I love about the hobbyist community is that it does an invaluable job of testing software and user interfaces. I know we did a lot of this together at…"

Kenn Sebesta commented on IKE's blog post Quadrocopter failsafe algorithm
"What they're showing isn't so much a technological feat as a mathematical one. My guess is that they started with Lee brackets, in order to discover the controllable space, and then depending on how tricky it was to go there they…"

Kenn Sebesta commented on lianpinkoh's blog post Techpod Drone ready-to-fly to Belize!
"Got a response from W. Garris on the question of the the TechPod's center of gravity. He says "On the spar is neutral. 1/4 to 1/3 MAC (root cord is MAC* ) is normal." I don't have my TechPod to measure the wing chord, so I'm…"

"Looks great! All the mods are really interesting.Out of curiosity, where did you get the 85-90mm C.G. range?…"

Kenn Sebesta replied to Michael Ratcliffe's discussion Range Problem with 433Mhz Radio
"@Andreas Baumgartner Good find, those are indeed 2.4GHz antennas. Specifically, they're called coaxial dipoles, which are used because they're cheap to manufacture and easy to connect to*. In the classical approach, the shield is pulled…"

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"Ghislain-- Be very careful about shorts. It's a close fit, which becomes impossible to manage if you have soldered on the other USART pins. Since I hadn't soldered on the pins, I was able to get in there and apply a tiny bit of twisting…"

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"This is absolutely not what lilvinz would recommend, but here's how i did it: I just had to cut back the 5th and 6th header pins, which you can (barely) see in the photo. Note, wire lengths cannot be very long for flashing to work. It…"

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"K. Finisterre's explanations are possible, but not plausible once you consider the source. "There are too many honest journalists... to chase claims made by people with a deserved reputation for carelessness and dishonesty.…"

Kenn Sebesta commented on Nick Weber's blog post My Techpod Nears Completion!
"Thanks, guys. As I'm nearing completion, the next question I have is how the bay doors and gimbal are supposed to assemble? Maybe just a photo of the bay doors open and closed, and the gimbal assembled mounted to servos would be enough."

Kenn Sebesta commented on Nick Weber's blog post My Techpod Nears Completion!
"Where's the center of gravity on the techpod? I'm trying to finish mine up, but I can't find a figure for this."

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"That system config error is because you're trying to arm the model while it is in an inherently unsafe configuration. You might have left one flight mode in manual, for instance. In order to interpret this error more informatively, check the…"

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"Not sure why people would think of an alternative manufacture CC3D, or that we (Tau Labs) would design cases. This board is not produced by Tau Labs, it's produced by Quanton Gmbh. It's weird to want to force an independent manufacturer…"

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"@OlivierD What's neat about autopilots right now is that they've basically become commodity products. You can design the hardware in a weekend, with an extremely good chance of success on the first try. After that, it's all about…"

Kenn Sebesta commented on lilvinz's blog post quanton flight control
"@Guy This is getting severely off-topic, but I am funded by BCI to build a bat-tracking UAS. It seems that there's a lot of us looking into UAVs for wildlife research these days. FYI, while Freedom is one of our two reference platforms, there…"
