Jack Crossfire commented on Leon's blog post BOB4 - new website in english! (Indoor UAV)"Downward facing camera guidance is done all the time, but it's surprising no-one has thought of using markers on the floor to guide it through a building. Whoever does a line following copter will be the 1st."
Grips commented on Leon's blog post BOB4 - new website in english! (Indoor UAV)"Okay, sounds logical!"
Leon commented on Leon's blog post BOB4 - new website in english! (Indoor UAV)"There is no need of a sensor at the rear. The UAV can rotate so that it always faces 1 whall in front. Furthermore, I decided to put battery at the rear of the UAV, and it would have been difficult to incorporate another US rangefinder."
Grips commented on Leon's blog post BOB4 - new website in english! (Indoor UAV)"This is really interesting Leon. I have to congratulate you. Is there any reason why you did not incorporate a fourth sensor on the rear ?

Leon commented on Leon's blog post BOB4 - new website in english! (Indoor UAV)"@Jack :
With the sonars, you are right : I need to stay near a wall (up to or 3 meters is good).
But with the Wii-camera, if several IR spots are put on the floor the UAV could theoretically navigate through a building. Unfortunately this…"
Jack Crossfire commented on Leon's blog post BOB4 - new website in english! (Indoor UAV)"That's $100 of sonar modules. That's the 1st time someone got this to work, but it needs to stay near a wall. The next step is map construction & navigation through a building."

Leon commented on Leon's blog post 3D position estimation with a Wii-Remote camera"@ Roald:
Sorry, but I don't have the reference of the lenses anymore. I have totally disassambled the 2 lenses that I used."
Roald Baudoux commented on Leon's blog post 3D position estimation with a Wii-Remote camera"Hello,
Can you give more information about the lenses (diameter, focal length, provider) ? This would help a lot for a non-drone project using the Wiimote IR camera.
Thank you in advance."
Leon replied to agmatthews's discussion Arducopter navigation with Wii camera"Why is it a so big issue? We are talking about hobbyist drones, not "mass production" drones. I think that every hobbyist interrested in having a wii camera can buy a wii-remote and disassamble it. Unlike others electronics products,…"
agmatthews commented on Leon's blog post 3D position estimation with a Wii-Remote camera"Leon,
I've has some success with a wii camera on my arducopter see http://diydrones.com/xn/detail/705844:Comment:662476
I agree with your comments about how we could use the wii camera.
One thing I think it would be really interesting for is…"
Leon commented on Leon's blog post 3D position estimation with a Wii-Remote camera"@ Randy : Thank you for this idea. The assembly with "hot glue" works fine now. I don't want to use a more complex solution for the moment.
@ agmatthews : I think that it would be more robust to use :
* A sonar for altitude
*…"
agmatthews commented on Leon's blog post 3D position estimation with a Wii-Remote camera"Leon & Randy,
I've had a play with a wii camera recently and written it up here -> http://diydrones.com/forum/topics/arducopter-navigation-with-wii-camera.
I'm interested to hear if any one thinks it worthwhile integrating this type…"

"If you want to get more sophisticated with mounting the lense, you might try making a custom lens mount using a 3d printer (or a 3rd party 3d printing service like shapways.com). I've done a lot of investigation of lenses and lens mounts…"
Leon commented on Leon's blog post 3D position estimation with a Wii-Remote camera"For the lenses, I tried several configurations. I use 2 lenses that come from mini camera lenses.
When you look throuh the lenses assembly (with your eye), the image must be clear and wider than naturally.
And yes, the 2 lenses are just fixed with…"

3D position estimation with a Wii-Remote camera
Posted on September 3, 2011 at 12:14pm 16 Comments 6 Likes
In this video, I am using a UMI, a sonar for altitude, and a wii-remote camera. The wii-remote camera is a very small camera that is included in the wii-remote.
The wii-remote camera gives directly the 2D coordinates of the IR spots in the image. It's interface is I2C. This is really a great sensor!
On my UAV, the wii-remote camera looks under.
I put IR LEDs on the floor.…

On this video, you can see another autonomous indoor flight. I just implemented translations displacements.
I still plan to take part to the IMAV2011 indoor competition.
The next task is to implement simple vision sensors so that the heli can locate itself even without walls…

Here is another autonomous flight. The UAV just tries to hold a fixed position.
Remember that this UAV is 100% autonomous with its own sensors (sonars + IMU + magneto).
The autonomous part of the flight begins at…
