I am new to this community. I am from France, and I am building robots as a hobby.
I have just begun a new project called “BOB4”, which will be my 4th robot. (my previous robot can be viewed HERE). The hardware of BOB4 is ready and tested. I am now trying to program it. I am now working on IMU software (small video HERE).
Some pictures of my project.
My aim is to make an autonomous indoor UAV, based on a coaxial helicopter, and on a custom electronic board. I want to make it alone, but I plan to share my project here.
Why coaxial heli? Because it is a very stable platform, and small enough for indoors flights.
Your community is a great source of inspiration for me. That’s why I jointed in.
Some characteristics of this project:
I use one external power supply (8V 50W) for tests. I had to add some electrochimical capacitors to this power supply.
The 2 PCB of my BOB4 are designed by myself using Eagle (demo version). They were manufactured by OLIMEX, an European (Bulgaria) electronic manufacturer.
I have removed all the electronic of an existing "radiocontrol". I then placed a bluetooth module, a PIC microcontroler, an LCD display (4x16 characters), a link to the serial port of my PC (using a MAX232) and some switches. The board of the new radiocontrol was made using "wrapping". I want to use only one radio link for all data needed: manual control + orders sent via PC + programming + data feedback from heli.
I added a very simple "failsafe": I can cut the power of the motors and servo via one switch of the radiocontrol, or when loosing the radio connexion.
I will keep this page updated as soon as possible. Meanwhile, do not hesitate to ask me any question, or post any comment.
that is funny i am working on same concept ,..
So is there an reason why you didnt use any ardupilot ? for control ?
And did you find an way how do dertemine indoor how far you went in meters ?
hint would be great
I don't use Ardupilot, because I wanted do do it totally by myself: hardware design and programming. My goal is to learn as much as possible.
Furtheremore, I don't like the concept of the ardupilot: several 8 bits microcontroler. I prefer to use modern 16 or 32 bits microcontrolers, and only 1.
