Designing an Autonomous Helicopter Testbed: From Conception Through Implementation

2008

The presented research is designed to benefit the entire UAV researching community by allowing in depth access to an area of research that has been typically classified as too expensive and too time consuming to enter.

Publisher: ProQuest

About this book
This dissertation overcomes existing barriers and limitations by describing and presenting in great detail every technical aspect of designing and integrating a small UAV helicopter including the on-board navigation controller, capable of fully autonomous takeoff, waypoint navigation, and landing. The presented research goes beyond previous works by designing the system as a testbed vehicle. This design aims to provide a general framework that will not only allow researchers the ability to supplement the system with new technologies but will also allow researchers to add innovation to the vehicle itself. Examples include modification or replacement of controllers, updated filtering and fusion techniques, addition or replacement of sensors, vision algorithms, Operating Systems (OS) changes or replacements, and platform modification or replacement. This is supported by the testbed's design to not only adhere to the technology it currently utilizes but to be general enough to adhere to a multitude of technology that have yet to be tested.

    Great helicopter, terrible controller

    Video review on youtoob, search for "Syma S800g 4-ch coax review March 2012"*** update 4/26/12 see note below ****With the seminal 3-channel S107g (and it's Cobra/Marine Heli/rainbow colored variants) now out for over 2 years Syma finally upped the ante with a 4-channel coaxial micro heli.The 4th channel is for sliding or strafing left and right, which is what real helicopters can do and 3-channel helis can't.So is the S800g a good choice for those looking to move "up" to 4-channels? Maybe...The heli itself is a triumph of lightness and clever design. The controller, sadly, is a failure.For youngsters interested in mechanics and flight it could be a very educational and fun toy. Just about everything is assembled with little screws and a nice screwdriver is even included, so with a little adult help they could take it almost completely apart and learn how gears, batteries, motors, printed circuit boards, LED lights, and airframe structures... 4/5 Kurt (Philly USA) - See all my reviews Verified Purchase(What's this?)

    10 out of 10 for the helicopter, minus several million points for the controller.

    I would love to give this model 5 stars because lets face it, a four channel helicopter that sits in the palm of your hand for $30ish sounds great - and it is, but the 'new' controller is terrible and spoils it - please be aware.Most people reading this are likely to be either first time buyers/flyers buying for themselves or perhaps their older child (check out the Syma S107G or Syma S111G) or, like me, they are adults (although my wife and kids may argue the point) with a small fleet of these things, eagerly awaiting a new model and if it's four channel - all the better. But don't be too quick to part with your hard earned cash unless you have hands the size of a very small child or have too much cash and want to get rid of some of it. (Unless of course you are a very smal child in which case you may still want to read a little further, and make sure your parents know you are buying rc helicopters!)

    Not for newcomers. Lots of fun if you have a S107G remote handy, but otherwise it's very frustrating.

    First time buyers: Get the S107G. Not the S800G. You will not regret the choice. Both helis are for indoor use. Not outdoors. You don't need to take a micro heli outside to have fun.Hobbyists: If you enjoy a challenge, you'll like the S800G. Go for it.Enthusiasts: This is a really sweet heli if you've already got a spare remote from an S107G. Otherwise, I don't recommend it....The S800G is easy to fly with a remote from an S107G. (Or other *recent* Syma gyro Micro heli. An original S107 remote refused to work with the S800G.) It's not very speedy in forward-flight, so it's not going to win races, but it makes very tight turns with nearly instant responses to the controls. It's so spritely that it hardly needs thought to maneuver it. Like the S109, in tight spaces this thing can fly circles around an S107. Unlike the S109 it's big and beefy-looking with a strong metal frame and the battery lasts about 10% longer in flight (at the price of... 4/5 Hey Mo!!

    Long term review - 700+ flights 500+ crashes

    Simply put, this thing is stable and durable. It's both a great 4 channel trainer and a great indoor flyer for more experienced 6 channel pilots. I now have 8 helicopters, ranging from the V911 all the way up to brushless flybarless 250 class collective pitch, and just about every other well known 6 channel helicopter in between. This is the best built most stable helicopter I own. I have over 500 indoor crashes on hardwood floors and so far repairs have totaled less than $5. I have replaced one flybar and one rotor blade, both a victim of full speed crashes into a brick fireplace. I bought 5 of the 200mah batteries with it, and flight times are just now starting to get shorter. I'm not sure if it's the batteries or the motor starting to wear out, but either way that is very impressive longevity for both.While this is fast for a beginner helicopter, it is actually much slower than a 6 channel flybarless helicopter. Also if you let go of the right stick, it will self level... 5/5 Barry K. - See all my reviews Verified Purchase(What's this?)

    IF YOU ARE CONSIDERING TO PURCHASE THE WL V911 RC HELICOPTER YOU HAVE TO READ THIS!

    I bought the V911 because of all the reviews I read about how tough this helicopter was. We bought two. One for me and one for my wife. I am 57 years old and my wife is 54. We are still kids at heart. We have had so much fun and laughs with these toys that is unbelievable! These helicopters have taken so many hard crashes and still keep flying. One hard crash broke the balance bar on my wife's but they were cheap to replace so we ordered extras for the future. This morning I went outside with mine and had to switch it to mode 2 to give a little more edge against the light wind that was blowing. As the wind picked up to about ten mph it was a little harder to control. My wife went outside with hers later that day and the wind was blowing a little harder. I tried to tell her it was to much but she had to see for herself. I asked her to wait for me so I could watch.
