Quadcopter Motor Type? Answered

Hi, I'm working on building a quadcopter.  I have everything figured out, but I'm wonder what motors (and where) I should get.  I would also like that motor to have a propeller mounted on it.  I have seen many Instructables for quadcopters, but none of them specify the motors/propellers.  If you could answer this, please do!  Thanks.

Motor type / Arduino control

I am looking for a motor to control via Arduino. I know such a thin exists but am not sure exactly what it's called. Basically it is a motor but instead of rotating a shaft it make the shaft go in and out. It doesn't need to apply much pressure just a little tap. I thought it might be called an actuator and is similar to a solenoid I suppose. Any idea where I would find such a thing, what it would be called and how to control via Arduino. Thanks. Phil

Different types of motors on the same arduino?

So I am still learning Arduino but I've already built quite a few robots. I'm stepping things up a notch by building a robot with several motors. I am using 9g servos, stepper motors, standard servos, and regular dc motors with l293d ic. I am also using 2 ultrasonic distance sensors. There will be 14 motors in all but I think Arduino Uno can only handle 12? I will be using an Arduino Mega, so will that be ok? I also want to know if you can put all these different motor types on the same Arduino and if it is possible, would writing a code be really complex?

Help with Dynamo types

I have a question for everybody out there. It has been a very long time since I did this type of electrical design work, and for the life of me I can’t remember the principals. I know there are many different ways to generate electricity by using mechanical motion, and converting a motor into a dynamo is very easy. What I am trying to do is to make a brushless dynamo. I have taken my inspiration from a cheap hand cranked torch, and intend to improve on it a lot. In this torch it has a coil which has a flat disk magnet sitting above it. The magnet is spun creating the charge in the coil and is used by the LED's in the torch. What I want to know is how specifically the voltage (potential difference) is created in the coil. My experience of stationary coils is where the magnet is rotated inside the coil. Could someone please explain it to me? Many thanks.

Controlling a motor with PWM

I'm building an ROV for the MATE ROV competition with a high school team this year.  For this year's competition, we've decided to control our bot via an Arduino Mega, and we're using PWM to potentiate the thrusters.  As the person designated to electrical, I fortuitously have no idea how to set up an intermediate step from the Arduino to our thrusters.  I've looked into H-Bridges with both Relays and Transistors, and defaulted to the transistor. How would I choose what transistor to use though? I've tried several (all BJTs) and they're giving me nothing but problems.  Should I switch to a FET? Should I use a P type and an N type, or only one?  What specs should I purchase them with?  Do I ask too many questions? Help!  (I'm trying to control a 12V 6A motor with a 5V Pwm signal. Thanks!)

Help with what type of motor I should get

Ok well I've made a cord/wire reel for a 30m long internet cord, that I use for my xbox 360. I made it using 2 of those cd stacks holders. like this:[=====] II II II II[=====]Then put a cut half newspaper over so that the cord doesn't have to make tiny circles.It's really annoying when I reel the cord back in cause I have to turn the reel or else the cord gets twisted. I cant just grab the cord and wrap it around the reel. If you dont get what I mean then think of it as if you had pack up some string so you grab the string in one hand and use the the other to wrap it around. Thats what I cant do instead I have to rotated the hand thats holding the string other wise the cord gets twisted.So what I thought was that I could either get a motor that reels it in for me and I can also pull it out without damaging the motor or I could use something that you use to reel in a garden hose.The cord and the reel way a tiny bit over 1kg.Any ideas on what motor I shouldget or how to build the reel in thingy.

Treadmill Motor Control

I have a Horizon T101-04 treadmill that has a control problem. The motor is definitely good. I suspect that the motor control board is good, and the control panel board is bad. The control will not reset or go into diagnostic mode. I want to replace either the control panel board or the entire control system. The motor is 90V DC. For amperage, the motor label says "19A S6 25%" which has no meaning that I understand, other than perhaps that the maximum amperage is 19. The label says "APMS" rather than "AMPS", and I wonder if the "S6" is supposed to be "SC" for "stall current." All of the characters on the label are very legible. To replace the entire set of controls, I can use an industrial DC motor control, but how much horsepower does the control actually need to be able to provide? I don't think that the one on the treadmill actually provides 19A, and is probably close to 1 HP or so in its capability.  To replace the control panel with something else and keep the existing motor control, what do I need? Do I need some type of complex driver circuit? Does it need feed back from tach sensor to do a good job of keeping the speed steady?  If it will work well, I want a simple control set up like a KB Electronics KBMD-240D to which I will add a safety cut-off switch with a lanyard.

Choosing drive motors for kids riding toy

I'm building  "robot horse" for my daughter, and have the metal frame mostly complete.  The plan for locomotion is to mount reversible powered 6" wheels to the outside of each hoof, and steer tank-style. My biggest challenge is finding reasonably priced, reasonably powerful drive motors for each wheel.  My issues are  1)  I'm inexperienced at specing dc motors.       A) I'm not real sure how to translate published specs into real world motion.  I don't know exactly how much power it takes to get this reliably moving over rough ground to a top speed of around 1 mph.  I also don't have a good sense of much voltage you can pump into a DC motors.  (IOW, should I be able to push 2 x the rated voltage for a quarter second to get it moving? Will the motors naturally increase their amperage at a constant voltage (and thus power) as they are resisted by torque?)  How much power will starting from a stop take?  What about a slight uphill slope?     B)  I'm not sure what form-factor is best:  Gear motor?  Gear motor with final drive belt?  I would like to use worm-gear motors, as I think it would be safest if the wheels didn't move when unpowered. 2)  Hunting around supplier web-sites, I see lots of $20ish gear motors that use 5-20W of power.  Great price, but would 4 of them make enough power?  (See #1A above)  Also, I see lots of fractional HP motors for >$100 that would unquestionably be strong enough, but would cost more than the project justifies.  I found very little in between.  Are there motors and gear boxes that could power this at a reasonable price?   Relevant clarifications and details: 1)  The horse is about 40" high at it's withers (shoulder) 2)  Frame is made of 1/2" square tube steel. 3)  Normal rider + vehicle will be about 150 lbs.  However, unquestionably, larger kids (or multiple small kids) will at some point hop on it and try to ride it.  At 250 lbs. rider+vehicle weight it doesn't have to go fast, but shouldn't burn up the motors. 4)  It'll be powered by a lipo battery pack that shouldn't have any issues with 20A+ max currents and can be sized as needed for voltage. 5)  I'd like to keep the motors and gears <$200 total, if possible. 6)  "Rough ground" = flat grassy turf or reasonably smooth gravel. 7)  Motors need to be reversible. Can anyone lend some perspective on what type of motors to buy for this?  How much power/torque should I look for?  Any advantages/disadvantages of any particular gearing style for this application? I am assuming that motors on each wheel are the way to go, but if there are any other power transmission schemes that would work better, I'm all ears.

Making an Arduino-based robot with motor controller shield - what's the best battery(s) to use? Answered

I have this robot I'm trying to make, but can't seem to solve one problem.  I have an Arduino Uno clone with a Rugged Circuits Motor Driver shield, hooked up to a Tamiya Dual Motor Gearbox with the two motors it came with.   The Motor Driver requires at least 8V to operate, but the motors are designed for 4-5V.  (I'm not sure if having two such motors together means you need 8-10V, but I assume not) .  I figure I can use the PWM of the outputs to only run the motors at 25%, to keep them from harm(?) I tried at first using a 9V battery to supply it, but the current was way too low.  I figure I can either use 6 AA batteries in series, or get a ~9.6V rechargeable RC car type battery.  The Arduino is powered by a separate 9V battery. It's a simple setup so I'll just describe it here; -[battery] goes into the 8-30V input on the motor controller.    -two sets of +/- wires go from the motor controller's 'Motor A' slot to the left motor and 'Motor B' to the right motor, separately -the motors are hooked up to 58:1 gearboxes and turn 5cm rubber wheels, for differential drive. Seems like I might have chosen the wrong motor controller shield for the motors, but if I can make it work somehow, then I will. Any suggestions?

Best Type and Source for Omni Directional Wheels?

I am currently in the process of compiling a shopping list for an omni directional robot a team and myself are planning to put together. For this, wheels that go both forward/backward and left/right are needed. From what I have found, there are two variations: Omni and Mecanum wheels. Due to our design, we will be needing Omni style wheels.  However, doing some research, I haven't been able to find much of a selection! So far, robotshop is the only website that actively stocks them, and they sell two brands/types, one being VEX.  Is there a generic name for these types of wheels? Where would I be able to find more/a different source for them? Why are they so expensive? If you've used an omni wheel, what type/brand was it, and what was your opinion on it? The big problem is, is that we need to mount the wheels onto 5mm stepper motor axles. Half of the wheels I found on robotshop had square bores, and the other half used an interchangeable hub, none supporting a 5mm axle. Any ideas as of what to do here? We would like to get four wheels, preferably for less than 50$.

Elevator type platform for heavy, CRT monitor

Currently, when I stand, I raise the mouse on a box and elevate the keyboard on a piece of foam and I peer downward to look at the monitor. This is not always a good way to see everything on the monitor.  What kind of simple elevating/lowering platform could be constructed so that the monitor can be raised to be level with my head when I stand and lowered when I sit in front of it? I suppose some electrically powered or non-electrical hand-cranked platform would be fine. Remember: both the motor, hardware and platform have to be able to lift, lower, and support a heavy CRT monitor which has a plastic platform holding a printer above the monitor. [Due to severe space limitatons where I live in my ultra-tiny apartment, I can't really use a shelf to hold up the monitor when I stand, and besides, it would be a pain in the neck to frequently lift/lower and set in place the monitor on either the shelf or on the desktop.] Thanks

I"m trying to replicate something similar to these: http://www.youtube.com/embed/OZuTA1TnhXo http://www.theantennafarm.com/catalog/index.php?main_page=product_info&cPath;=264_467_1202&products;_id=1619&zenid;=830b00255bfc07a392e02535506a3296  http://www.rfparts.com/diamond/k9000photos.html Basically, I'd like to have a 3-4' fiberglass whip that I"d like to raise/lower at my desire.  I'm unsure of which type of motor or parts to use- would anyone be able to assist with a parts list of some sort for this type of project?

Auto egg turner motor. What motor do I need for my incubator?

I built an incubator from a redundant wine cooler but the motor wasn't up to the job. I had underestimated the total load and stripped the gears in the gearbox. Can someone tell me in very basic terms what I need to change and where to look for them? Also, the top connection needs to be a ball and socket type affair (not very smooth at the moment). Where do you buy components like that? Thanks. Paul http://www.backyardchickens.com/web/viewblog.php?id=33362
