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.

    Can't go wrong with a Syma!!

    First of all, I wanna say I haven't flown many helicopters. Quadcopters have been my go-to rc hobby but I was very excited to try this helicopter. Syma is a brand I am very familiar with and I know from previous experience that they have good quality products. This helicopter has two sets of propellers, one on the front and one of the back. This makes it a stable flyer. There area non moving wheels on the bottom of the copter, 4 to be exact, that make it easy to take off and land. The charging port is located underneath the bottom, along with the on/off switch. For me, it took about 45 minutes to charge it and flight time was around 6 minutes. Once it is fully charged you are ready for flight. I placed it on my helipad and proceeded to get it in air. The transmitter is a decent size and is pretty much standard and easy to use. It takes 6 AA batteries. I don't know if others had this issue but the batteries don't sit in well, when first putting them in. They flip around and once you... 5/5 randee555 (Virginia) - See all my reviews Verified Purchase(What's this?)

    Great Little Quad Rotor Helicopter

    I own a Syma s107 and just had to try the Chinook for myself.What a great little machine! The trim is a little more complex than the 107 because of the front/rear drive concept but Syma have done a great job of making a potentially complex business very simple. A technological triumph.Trimming for spin is done as on the S107, with a knob set between the sticks. Trimming front/rear drift is done by clicking on the labelled buttons on the top of the transmitter. Couldn't be easier.Flight-wise the helicopter is very responsive and stable once trimmed. It has the typical gyro-stabilized contra-rotating design issue of the helicopter fighting its own forward/backward motion, resulting in this instance in a visible - but small - tendency to see-saw. As with the S107 the trick to fast forward flight with this design is to fly a serpentine path - by the time the gyro has "figured out" what the helicopter is doing and started to fight it, it isn't doing the... 5/5 Stephen Mann (NY, USA) - See all my reviews Verified Purchase(What's this?)

This review is from: Syma 16.5CM S026G 3.5Ch 3 Channel Mini Chinook RC Helicopter Gyro Small Toy Gift Army-green (Toy) As the previous reviewer said . . . make SURE you get the gyro version (S026G).Without the gyro (S026) it is almost impossible to properly control this Helicopter, especially if you're a newbie.Lots of fun indoors. As it's so small, flying outside is possible, but there must be absolutely no wind.Fantastic if you can get a Gym or some large empty hall to fly in.Great for 8 - 80 year old children.

    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?)

    Charger failed on fourth charge attempt

    Pros:* Significantly better range of motion, speed, and range than 3 channel helicopters I've previously flown (i.e.: Syma s107)* 2.4 ghz works *much* better than infrared, no signal loss issues at all* Impossibly good resilience to crashing given how it's all thin plastic* 2 batteries for quick swappingCons:* Charger failed on 4th charge attempt (LED's went out and stayed out, batteries don't charge)* 4 trim controls is daunting at first, especially with an audience O_O* I've noticed that when the battery starts getting depleted, the amount of trim needed changesCharger: always plug the charger in BEFORE you insert a battery.

    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. By the time I made it outside she was using the skimmer net for our above ground pool to fish the helicopter from the... 5/5 Rodney Smith - See all my reviews Verified Purchase(What's this?)

    This little quad is a beast!

    Customer Video Review Length:: 2:06 Mins This quad is all the way awesome! Crazy fast, responsive and extremely stable. I love this quad so much, Holy Stone sent me one to test and I bought another one after flying it 3 times! It's sooooooooooo much fun to fly.So it has 3 speeds and the yaw changes with each rate. In low it's very docile and the yaw is painfully slow. This is great for beginners though and in mid rates and high rates this quad is a little beast! The yaw is still on the slow sdie but the pitch more than makes up for it. Because of it's deep pitch in high, it can turn on a dime even with the slower yaw. This micro quad is FAST. So fast and fun!This quad has no camera or any extra weight to hold it back. It's a rocket in high and still very controllable. It has nice LEDs and the under body is white so it makes a great night flyer! (check out my YouTube channel for night flight videos!)Flight times are great, with about 8 minutes of... 5/5 Bo S.

    Great mini quad for the price!

    4/5 William B Betters - See all my reviews Verified Purchase(What's this?) This review is from: Holy Stone HS170 Predator Mini RC Helicopter Drone 2.4Ghz 6-Axis Gyro 4 Channels Quadcopter Best Choice for Drone Trainer (Toy) The product is fantastic for the price. I own many mini quads and this one is very stable for a beginner at the lowest rates and quite agile at the highest rates. The brushed cans (motors) on this quad are also quite large for a mini quad and it has plenty of power for even outside flight in mild winds for the experienced pilot. The prop guards are not intrusive like on many mini quads and barely protrude above the prop height. This allows for ceiling tricks in your house without damaging the props. My only compliant about the quad is its yaw rate. Even at the highest rate setting the yaw rate is still way too slow. The product would have been perfect if the yaw rate scaled the same as the other axis rates do. Bare in mind I am an experienced multi rotor pilot. I fly many of my quads without any self leveling. If you are looking for a starter mini quad that will allow you to progress your skills you can't go wrong with this product.
