About Me:
Travis Deyle, PhD (beambot gmail.com) - I currently work at Google[x] Life Sciences. Our team developed the glucose-sensing contact lens. I currently work on new (non-public) projects. - Previously a Co-Founder of Lollipuff.com (YC W13). I'm less active these days, but it's still alive and growing in the hands of my co-founders! - Academic background is varied: PhD in robotics from Georgia Tech; postdoc in "cyborg dragonflies" at Duke University. - More information: TravisDeyle.com & Hizook.com

Antennas are a critical part of any drone system -- whether for RF remote control or for telemetry & control. The cloverleaf antenna is a popular option owing to its reasonable gain pattern in the lateral directions and because of its circular…
"Also... I'm curious why the phase extension coax is labeled as 75-ohm after you've already added in a 50-ohm matching cable?"
"Typo: Coax cable is an an unbalanced feeder"
"HeliStorm, I'm happy to correspond via email. You can find my main email address on my personal website: TravisDeyle.com"
"Hey Chris,
This was actually part of my postdoc work at Duke after leaving Georgia Tech's Healthcare Robotics Lab. Here's a paper that describes the early system:

"This is pretty cool. There was some similar work a while back by robotics researchers using electric field sensing fish as the model. Basically, the researchers built arrays of electric field sensors to do the same thing (ie. "tomography" --…"
"EP Magnets are AWESOME. I wrote an extensive article about them over on Hizook a while back that explains the physics. Go check it out: http://www.hizook.com/blog/2010/12/07/electropermanent-magnets-prog..."
"My guess: Selling into government bureaucracies is difficult and expensive. So is offering quality support. Perhaps they also burden some of the risks associated with flying. Perhaps they went through the FCC certification process on the drone?…"
"If you're making any circuits out of copper tape, do yourself a HUGE favor: make sure to get conductive adhesive copper tape (I can't tell if the SparkFun product has conductive adhesive or not). I spent 4 hours debugging a touch sensor once just…"
"As many folks in the comments confirm, they're likely using an OptiTrack system. These have become fairly popular in academia as a low-cost vicon alternative -- 1/5th to 1/10th the cost with respectable resolution and update rates. In fact... my…"
"Heh, am I the only one who thought the crane was extending out of the image (via the drone tail fin)?"
"FYI, this is the same principle as the Neato vacuum cleaner's ultra low-cost laser rangefinder: http://www.hizook.com/blog/2009/12/20/ultra-low-cost-laser-rangefin..."
"Haha. Chris, you already covered this on DIYdrones when we wrote about it on Hizook. ;-)"
"Travis here -- one of the Hizook post authors, and a researcher in this field.
The key thing about wirelessly-powered sensors being queried by a UAV is that (1) the UAV can get to inaccessible locations that are normally tough to reach and (2) the…"

"Travis here (Hizook author).
@Chris, thanks for the kind words. I'm glad to see that you still follow Hizook. ;-) While the robotics VC landscape is lacking, I'm really encouraged by bootstrapped outfits, like DIYdrones. Based on the last…"
