Detailed Description

The Microduino Quadcopter is a flying four motor rotorcraft kit. The kit is designed to be fun and easy to assemble. When building this, kids learn about the different modules and the functions required to create the quadcopter.

 

Positioning and Orientation

The quadcopter utilizes a 3-axis accelerometer and a 3-axis gyroscope chip (MPU-6050) to determine its positioning and orientation. With this data, the quadcopter’s motors are able to compensate for orientation during operation.

 

Wireless Control

The CoreRF module (Core + nRF) adds wireless communication to the Microduino Quadcopter. The quadcopter can be remotely controlled by the included Microduino Joypad. Additionally, the included Microduino Joypad can be reprogrammed and used for other projects.

 

Microduino Series Modules

This kit incorporates various Microduino Series modules. The Microduino Series is a set of modules which are Arduino compatible, have a small form factor, stack-able, modular, and reusable. The modules were designed for hobbyists and tinkers to quickly create and prototype projects.

 

A Complete Kit

The kit contains everything needed to make the Microduino Quadcopter. Electronic hardware from the embedded processor (CoreRF module) to the motors and propellers are included. Also included are frame pieces for the quadcopter. A recharge-able battery is also included which can be recharged with a MicroUSB Cable plugged into the base board. The Open Source code is provided and can be modified for personal customization. Similarly, the Microduino Joypad contains everything needed to be assembled (including the rechargable li-ion battery).

  • Had seen a nice Youtube video recently on how to measure thrust with ducting propellers.

    1943, The Luftwaffe Fa 223 Dragon had just 2 propellers and later model was designed with 4 which is similar to most of the quadcopters available nowadays.image

  • Hugo - Seeing the design so far, the microduino itself with motion module could be retained to make a bigger copter, and retain joypad. The copter Shield is very limited to the motor driver current ( wire traces and component selection). The copter is using low inertia DC motors and gearboxes, which will likely need to be upgraded to outrigger brushless motors nd their drivers. The copter chassis is designed for a 3.3V battery 600 mAhr battery., which also limits motor size and flight time -- i.e. need also a new copter chassis for a bigger design.

  • Hi Sean - Maximum lift (force)- thrust is first on everyone's wish list to measure.:-)

     

    If you've ever done vector diagram ( also know as Free Body Diagrams)  if you know maximum thrust, you can figure out maximum payload lifting -- but of course if all the lift is used for weight, the copter never lifts.

    Lift is a function of motor speed, blade pitch, blade length and also restricted by the available motor torque. Motor torque is also variable based on the battery voltage - so there needs to be margin for a low battery.

     

    What lift is not used to actually lift the copters weight is available to use for upwards acceleration, and also the copter moves forward by tilting, so acceleration is done in x axis and also y axis , and then even some in Z dimension for turning.

     

    At the end , weight, motor speed & available torque, and propeller type are a compromise with flight time and aerial responsiveness.


    The easiest way to measure lift is to place the quadcopter upside down on a scale. At rest, the scale measures weight, at full speed  the scale measures weight + thrust.

    If that does work because of gyroscopes, then can mount the propellers upside down, and reverse the motor direction, to make the same measurement.

     

    I may just write simple code to brute force make the measurements rather than hack the open source code ( depending if microduino will share the shield schematics) .

    The copter code seems written by someone really good with embedded systems software , it is fairly complex, and has some comments. The joypad code is shorter ( not simpler)  with no helpful annotation. 

    It may take alot more time than Road Test allows to understand it well enough to make significant changes.

     

    Keep up the good discussions.

  • I do look forward to seeing your review.

     

    Maybe a few points to test:

     

    Remixing the code to do what you want

     

    Remixing the hardware, for better motors, better battery, etc.

  • One of my thoughts for the RoadTest was how to measure lift?

     

    A number of suggestions were posted on tasks the quad-copter could perform. I kept thinking about lift. Any payload added to the vehicle increase the lift requirement or more thrust from each propeller.

     

    My understanding (limited) in the realm, is that thrust determined by a number of factors. My initial thought was just speed of the motors but that is only one of a few that can impact thrust. I discovered the thrust must be balanced across all four motors if the platform is to hover in a fixed point. The electronics engaged to accomplish this feat is fascinating!

     

    So do you have any plans to measure thrust?

    image

    I'm curious about the results of such an experiment. The copter and known weight are placed on a scale. The copter is engaged to lift the load. The scale results will change as the copter engages. If the weight is sufficient so that the copter can't fully carry it, can you calculate the maximum carrying capacity? I made the  physical size of the weight size extend past the area of the four propellers. Maybe the load should be small enough to be inside the center of the vehicle? I seem to recall a fan on a sailboat blowing wind on the sails doesn't cause the boat to move.

     

    You have a excellent experiemental platform in the quad-copter when you get it operational. Or maybe not?

  • Congratulations

     

    It's a good candidate for how ducting a propeller increases efficiency and thrust as well.

     

    Eagerly awaiting your review/s.

  • Please feel free to ask any questions, Ill see if I can give answers or insights. Questions can make thinking, testing, and report out better.

  • Thanks GY for the share. I was reluctant to ask you questions for fear it would take away from your review. It sounds like you still have some obstacles to overcome before a review is on the horizon.

     

    My RoadTest Siretta Cellular Signal Strength Data Logger - Review was a struggle. The product was developed for Europe and then expanded to fill the American market. US cell phone networks use a different standard than Canadian cell phone networks. Lot's of things didn't work as described in the documentation.  It took a considerable bit of time and many remote log-ins to my home computer network in order for the vendor to gain access to the unit before a code release that worked was developed. I learned a lot from sharing with the vendor in England.

     

    I would expect with all that is published on the Microduino, that getting this product into the air would be relatively easy. It sound from your commentary you have considerable experience. I suspect like most companies the vendor is off to bigger and better things and the continued struggles in their old markets is something users have to live with.

     

    I picture these struggles coupled with kids saying "is it working yet" the formula for keeping kids for STEM:)

     

    I wish you the best of luck on your quad-copters first launch. I look forward to your RoadTest Review posting.

  • Thanks Sean - This kit is labeled for ages 12+ , so it should be cookbook.

    There is alot of documentation, however there is maybe too much. The tutorial is not translated well and has old info in it. It seems a Quickstart guide was generated with alot of documentation improvements, however I started with the tutorial and kind of waded thru it, and then referenced the Quickstart Guide, and found some of my noted conflicts were answered. Some of the documents need condensed together with all updates.

     

    The quadcopter is still grounded. There is a simple procedure to execute using the JoyPad joysticks on quadcopter power up, to prove to the quadcopter it has a valid and active controller before enabling it to fly. I'm stuck there right now, and have emailed microduino for help. The procedure doesnt seem to be very dependable.

     

    I have several Flysky Radio controllers for my robot projects. Those RC controllers have a separate procedure called binding, selectable on the receiver by jumper, to acquire the signature of the transmitter and bind to it. Those radio controllers use spread spectrum on 2.4 Ghz , and this allows multiple controllers to operate in their immediate vicinity, and not to interfere with each other.   

     

    The joypad and quadcopter use a Microduino CoreRF is an AVR core board with 802.15.4 Wireless Protocol integrated. It supports any wireless modules based on 802.15.4 Protocol, including Zigbee, MAC/6LoWPAN and RF4CE. The 801.15. 4 uses a multi-code modulation technique called parallel sequence spread spectrum (PSSS). I copied and pasted this info. :-)  

     

    With this tidbit of knowledge, I wonder if the code of the Joypad and quadcopter could be hacked to get rid of this wacky and awful "pairing" routine that doesnt seem to work reliably since the Wiki says if it doesnt work, keep trying several times, and then if still doesnt work reboot everything and start again. I'd rather set an ID number in the JoyPad and use the Quadcopter code to load a matching ID number so the pairing happens automaticaly. If doesnt then the JoyPad says it doesnt see the quadcopter.

     

    I've unsuccessfully so far waded thru the software to find the code that drives that Blue LED, even if I had schematics, the silkscreen nomenclature doesnt always translate to the software name. I figured if I backtrack thru the code, maybe I can hack that particular permissive. All that takes alot of time and perserverence.

     

    The Joypad is pretty cool, the quadcopter is pretty solid hardware wise, however sitting on the ground trying to get a blue LED to light isnt very fun, and also considering I dont have faith that the document is accurate. 

  • I have an affinity for the RoadTest. It was a review I was hoping to secure. After reading your posts I am a bit relieved I wasn't awarded it. I'm not confident I would have had the knowledge to pull it off.

     

    Pulling on a thread of knowledge to find it takes you no where, I find frustrating. Lack of documentation and its poor quality seems to be a theme in RoadTests. I was going to suggest it be a scoring metric on the RoadTest Review post. I'm not sure if it would change the way vendors view documentation.

     

    Can you clarify the status. Have you succeeded in getting the vehicle off the ground? Other than carrying it to the car:)
