Andrew Helgeson commented on Andrew Helgeson's blog post My new UGV in alpha"It has 4 motors, this might have influenced me a bit!
In the video it is being controlled with a 2 channel Sparkfun Monster Motor Shield.
Because it does have any suspension besides the wheels, just like the loader, if one wheel looses contact…"

"Andrew,
Nice work. Looks good especially the conversion to wheels inplace of the tracks. Are you using skid steering to turn the chassis?
I am presently building a Traxxas Emaxx from new parts purchased off of eBay. I plan to mount a platform on the…"

This is what I've done to my Dagu Rover 5!As it comes out of the box.I was shipped the 4 motor version.I live out here in the "boonies", so I get to talk to guys that use and maintain earth moving equipment.There is even a guy that restores old tractors, stationary engines and such.Talking with them was great, they all said powering a track at BOTH ends was a total waste of time and…See More
Andrew Helgeson replied to Jason Tinacci's discussion Sonar help needed"Are you using the sonar for altitude or collision avoidance?
If you are sending out sonar "pings" horizontally, the prop "down wash" is going to screw with your ranging, the faster the air flow across the sonar path, the further…"
Andrew Helgeson replied to Thomas J Coyle III's discussion The Raven Drone"Yeah, that was my idea as well, something I could sit in and fly!
I was planning to scale my model %400 and power it with a BMW R80 engine.
Models are great, FPV looks cool, but actually flying is way better!"
Andrew Helgeson replied to Gary Mortimer's discussion Cracking Link, high altitude glider/balloon"Thanks for posting that link!
That is way cool!
Have you seen some of the recent projects where people send up balloons to 75,000+ feet?
Great video footage on youtube!"
Andrew Helgeson replied to john the welder's discussion 50%scale (how do you scale down a design?)"With the obvious stress points, wing roots and spars, engine mounts, landing gear mounts, think about how much abuse it will have to cope with.
The other thing you have to take into account is tailplane area, I have found this out the hard…"

Andrew Helgeson replied to Wyliest's discussion Cheap and eazy airframe to be made available to all"That looks like my plane!
lol
Amazing how similar solutions to a similar problem come about!"
Andrew Helgeson replied to Wyliest's discussion Cheap and eazy airframe to be made available to all"I built my fuselage (see pics) in a few hours. Tail plane took a little longer, while I was waiting for the polyester resin and paint to dry.
It's mostly cardboard, with some balsa and 3 ply where I needed strength for the landing gear and…"
Andrew Helgeson replied to Kevin L.'s discussion Strobe Light for UAVs"If you know someone at a fotolab, see if you can score a couple of those cheapy disposable cameras with built in flash.
They run off 3V. Just trigger when the "Ready" light comes on.
It's cheap and nasty but works.
I've used them…"
Andrew Helgeson replied to Thomas J Coyle III's discussion The Raven Drone"Wow!
The grey one is sooo sexy!
How much does it cost?"
Andrew Helgeson replied to Thomas J Coyle III's discussion The Raven Drone"Have a look at my photo's.
My plane is a lot like this one.
My prototype was 1/4 the size, about 320mm long, 150 mm high, 40mm wide, large horizontal and vertical stabilisers, no controls, just a "chuck" glider and it was very stable.…"
Andrew Helgeson commented on Chris Anderson's blog post Using a mouse chip to measure optical flow"Keeping it real simple, use a slit with a couple of photo detectors, 1 slit/axis.
Its the way PIR motion sensors used to be made, before they went to the fancy fresnel lens.
I started experimenting with this technique on the bench, watching the…"

I couldn't believe it when I found this site!
If you have a look at my photographs you will see my under construction aircraft.
It is 1200 mm long, 90 mm wide, 220 mm high.
Made from cardboard, balsa, 12 mm square aluminium extrusion tail boom.
It will be powered by an OS 28, with a pusher prop.
Weight at the moment is under 1kg, with no engine, canopy "glass", or radio gear.
The whole point of this aircraft design right from the start was
