SIR. BENSON I.AM NIGERIAN ENGINEER I WANT TO LEARNING HOW TO START ELECTRONIC CIRCULT DESIGN SIR INEED YOUR HELF
@BASHIR You might start with a program called “Eagle PCB”; it’s free for personal use, and there are a lot of examples and tutorials available online.
It would be great to see examples with Javascript using the Tessel project tessel.io/
Regards, Nicholls
@Juan David Appreciate the feedback, but writing about a controller in particular makes the focus of the series too specific.
Hello there! I was a start up … Iwoul like to know wheather can we connect receiver to arduino and arduino to motors
@anil You can connect a receiver to an Arduino, but it takes quite a lot of programming since the receiver outputs in timed pulses. It’s best to offload that onto a separate flight controller if possible. You can get inspiration from the MultiWii project which is based on Arduino.
Great explanation, I think these lessons really help beginners get through the basic steps of building their own UAV.
I have a few questions that I’m hoping you can answer, if you don’t mind. I’m trying to build an autonomous UAV that uses an on-board Android phone setup for video, accelerometer, gyroscope, and it’s processing power. My main goal is to be able to program the drone using Java code. I found a website that talks about making a “smart” drone using an Android phone and Java programming, but it’s a bit confusing.
Here’s the link to the site: https://software.intel.com/en-us/android/articles/how-to-develop-an-intelligent-autonomous-drone-using-an-android-smartphone
It talks about using a Pololu Maestro servo controller linked to a “stabilization card” that is then linked to the ESCs. My questions are: How do you use a servo controller to control the flight of a UAV? And what is a stabilization card, is it just another name for flight controller?
I’m really stuck trying to figure this out and I could really use some help. Thank you in advance.
@Will The smart phone would need to be running an “app” which can process the gyro and accelerometer data in close to real time, and send signals to the servo controller which is then connected to the ESCs (a smart phone alone cannot connect to the ESCs, which is why the servo controller is needed). In the article, the “stabilization card” does seem to be a flight controller. The pololu servo controller was likely chosen because it’s small / lightweight, and has a USB port.
Sir what are the procedure to make a multi drone system for aerial display?
@Ashish Unfortunately that is beyond the scope of this series. There are not many multi-drone systems. Take a look: https://www.robotshop.com/blog/en/superbowl-drone-coordination-19905
Hey
I interested to build a drone with controller, that use Rasbary Pi that will passed the command to flight controller (where the commands can come from user by transmitter, or by the pi it self, for example when I want to implement go back home feature)
I read about controller such as Navio2 buy 200$ is out for my budget.
I there any recommendation for fly controller that cost 60$-70$ that I can use?
Thanks!
@ron Flight controllers are really meant to be “stand alone” (i.e no additional processors). What part of the project would require the processing power of a single board computer and how do you want to integrate it into the project? The “return to home” feature does not require a Pi and is actually implemented on most DIY flight controllers which have a GPS.
I understood the job of compenents, but I cant imagine how it will be attached to controller specially ( where is the pisition of attaching)
@mahmoud The best reference for that is the flight controller’s user guide. Normally you only need to connect the ESCs, the radio receiver and the GPS to the flight controller.
Hallo can you make for me control for under water dron comunication on optical cable ?
@palo We do not offer custom design services, but you will find many parts for ROVs, including tethers here: https://www.robotshop.com/en/bluerobotics.html
Sir, you said: “As single board computers become less and less expensive, expect to see a new generation of flight controllers which can run full operating systems such as Linux or Android.”
How far are we on that lane to day?
@Jan getting closer. For example the Navio2 autopilot is intended to be used with the Raspberry Pi single board computer: https://www.robotshop.com/en/navio2-autopilot-kit-raspberry-pi-2-3.html
( QUADCOPTER (UAVS) FOR BORDER SECURITY WITH GUI SYSTEM )sir I want the souce code for making this project kindly help me sir … I’ll be thankful for u sir
@Muhammad Osama Bin Aqeel We do not currently have any code for drones for use in border security. You will need to determine the features you need and compare it with what already exists on the market. Most flight controllers can record video in autonomous mode, and you can certainly do R/C FPV flight. Additional features might be night vision and thermal.
