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.

    This little bird rocks!

    If you are looking for a quick and short answer, then I'd say YES, buy it. Now if you have time and want to know a little about my RC heli flying experience then read on. I started flying the RC heli with an indoor, toy-grade, 3/3.5-channel, infra-red (The sun light will interfere with infra-red), coaxial (2 sets of main rotor/blades) model. It's cheap, slow, and stable, but less responsive to the control, and the fact that it needs a 20~30 minute charging time for every 3~4 minutes of play is just a pain in you know what. After I became pretty good at it (Also tired of it), I got crazy. I moved up to a 450 class 6-channel collective pitch single rotor model, which was a huge mistake. It's like from playing with a harmless toy to an upside-down lawn mower! It was a money pit! Every crash (Usually happened in 10 seconds after take-off) would cost me at least $10~$20 for parts and lots of time trying to repair and adjust it myself. Stepping from a 3.5-channel model to a 6-channel one is... 5/5 gt507866 - See all my reviews Verified Purchase(What's this?)

    Outstanding indoor heli with 2 warnings

    ***UPDATED REVIEW***I ended up getting another v911 and absolutely loved it so I had to try this heli out again. Wow, what a difference the 2nd one made. It hovers like a dream and flies so smooth. I don't think I was being very fair on my first review. However, there are 2 warnings about the batteries:1. The charger that comes with the normal v911 is much better than the h911. The v911 charger is very dependable and charge lights are accurate. However, the h911 charger is just plain junk. The light indicators simply don't work. See my original review on the battery charger below.2. I definitely recommend buying the batteries that Amazon says are typically bout together with the heli. The 2 stock batteries are fine but the additional 5 have more power, longer flight times, and you can fly over and over without waiting for another battery to charge.SUMMARY: As you can see from my original review, I'm eating my words.

    Great little heli for around the house!

    Like others have said, this is probably the best $45 dollars I've spent! I had a Swann Micro Lighting whose motor died after a crash that has been waiting to be replaced. The difference between these two helis is night and day. The Swann is way too tame by comparison being a coaxial and no aileron functions. The remote isn't half bad either with trim tabs for each channel, an lcd readout (although kinda cheesy), and a form of a dual-rate incorporated into the top button. The heli itself is attractive and practically unbreakable. I've crashed it numerous times, and the worst thing that has happened is that the canopy became dislodged. The gyro system is incredible at keeping the little bird's tail pointing in the same direction until you tell it otherwise with the controller. The tail will start to drift as the battery starts running low (Hint: it's a Lithium Polymer battery, stop flying it as this point and don't run it down anymore. Trust me, the battery will last much much longer)... 5/5 Matt S - See all my reviews Verified Purchase(What's this?)

They are wired but don't work.............................................................................................UPDATE:I figured out what I was not doing, and that was READ THE INSTRUCTIONS before proceeding to operate a complicated device such as this helicopter. After looking over the instructions, I found out that the two small buttons on the top side of the remote on both sides of the antenna is what operates the hovering motors.Therefore, I give myself 2 stars for not reading the instructions first, and I also what extend my deepest apologies to 4evelasting along with appreciation for their kind offer of a brand new helicopter.

    Nice Chopper

    I would say this is a very sturdy and robust RC model and at a very good price! I ordered 2 crash kits and an extra battery as I'm sure I'll need to replace the blades and the extra battery makes it more enjoyable not having to sit around for an hour to recharge after every 10 - 15 minutes of flight time.I bought this as a gift for my niece and she loved it! Such a cool helicopter, if you read the instructions carefully it is actually very easy to use. We crashed it couple of times at first but there wasn't any damage yet. My niece got used to controlling it very easily, even I tried it and had so much fun with it. She has so much fun playing with it. Its very easy to charge. You can use it indoor and outdoor which makes it more fun.

    Stable flyer!

    OVERVIEWThe Sky Rover Phoenix is an entry level fixed pitch (FP) single rotor helicopter with a flybar for greater stability. It is about the same size as, but 2/3rds of the cost of, the WLToys V912, which I also have. This is a step up in difficulty from small coaxial heli's and is probably not a good first RC helicopter model. The model is ready to fly out of the box and I liked the feel of the basic 2.4GHz controller, which has digital trims on all 4 channels, but no other features.INSTRUCTIONSThe instructions for flying the helicopter combine pictorial and written directions for flying the helicopter and are similar to the layout in other SkyRover heli's; they could be clearer but are easy enough to figure out. There are no suggestions for adjusting the heli, but the servo linkages are adjustable in length if the swashplate needs to be levelled.BUILD QUALITYThe build quality on the model seems to be quite good and I like the sturdy metal frame.

    Looks impressive but doesn't fly that way.

    2/5 Marianne Gordon - See all my reviews Verified Purchase(What's this?) This review is from: SkyRover Phoenix 4-Channel Radio Control Outdoor Helicopter (Toy) This heli looks big and impressive in the box. It appears to be a large Syma f3 type but doesn't fly like one.it is very heavy and sluggish and really too big to safely fly in the house unless you have a mansion with a basketball court inside .also the battery while adequate for sustained flight is built in like Syma s 107 and cannot be changed out to fly sooner than the hour or more that it takes to charge .the tail skid is too short to prevent the tail rotor from hitting the ground when landing I believe this is likely to cause the tail rotor drive to fail prematurely. Fly outside in dead calm conditions only or you will be playing wild goose chase. Help other customers find the most helpful reviews  Was this review helpful to you? , December 11, 2016

    Very Good, Large RC Heli!

    4/5 HappyDad - See all my reviews Verified Purchase(What's this?) This review is from: SkyRover Phoenix 4-Channel Radio Control Outdoor Helicopter (Toy) This is one, very nice RC heli!Large sized with nice graphics. Seems very sturdy.This is the first RC heli (3rd that I've ordered) that actually had power after charging and tried to work. It had a piece near the rotor that looked disconnected. I tried to connect it but couldn't without disassembly. I'm not that familiar with these devices so I just returned it.I feel certain that if the piece had not popped off (not broken, probably disconnected during shipping) beneath the rotor, this heli would have worked perfectly.Recommended for knowledgeable/experienced RC heli pilots.

    EXCELLENT CHOICE

    Customer Video Review Length:: 0:05 Mins I bought the Syma brand because I have had some of their helicopters that flew well inside with a lot of stability and found them to be durable. Santa got the Syma X9 quadcopter for the kids this year and I must say I am impressed again with the quality, functionality, stability and durable as well. You can fly these in the house as long as you have a vaulted ceiling. Our ceiling goes from 9' to 15' so we have some room. Otherwise, these fly very well outside much butter than the helicopters. The fine tuning trim buttons work great to get it to hoover hands free. It will easily fly 80 to a 100 fee up. It is very cool to have wheels, people are always amazed to see a drone that can drive also. The only thing I was not impressed with, which is small, is the steering on the ground in car mode is not proportional steering like more advanced R/C cars, so it is much more fun to fly than drive. Besides flying with ease and driving on the ground,... 5/5 J. Schroeder - See all my reviews, January 2, 2016
