  Wiimote-Raspberry Pi-Omniwheels-SBrick

  Wiimote Bluetooth to Raspberry Pi. Wiimote buttons mapped to directions and speed Raspberry Pi Bluetooth to SBrick Raspberry Pi camera streaming to internet. Next step is to use a Wii Classic Controller or Nunchuk

    Thanks to Jorge Pereira from where I cut and paste and take my inspiration.
    
    Let battle commence (not really, we are only in the Show and Tell section and the Lego is very fragile in any case)

    Paolo DGZ "in any case is not correct" according to me ahaah, yes, against robot wars middleweight robot for sure, but my tracked scorpion can flip an !k bot, and survive to lots of flips :3 ( http://www.brickshelf.com/cgi-bin/gallery.cgi?f=551825 ) anyway that...  more"in any case is not correct" according to me ahaah, yes, against robot wars middleweight robot for sure, but my tracked scorpion can flip an !k bot, and survive to lots of flips :3 ( http://www.brickshelf.com/cgi-bin/gallery.cgi?f=551825 ) anyway that bot look really weak, but i admire you work with raspberry and Sbrick! it is possible to control via raspberry or arduino+ bluetooth and ps3 controlle a bot? do you know how?
    
    thank for the attention!

    Kevin Hainsworth You might want to look at this thread and also the Retropie project.

I used a PS3 controller, Ubuntu 14.04, and Python to do the math. I haven't yet seen that the profile designer is capable of handling trigonometry or other complex control logic. I ended up using imaginary numbers a little bit, which I doubt is a priority for normal users.

    Kevin Hainsworth Oh my, imaginary numbers. That takes me back about 30 years. Ultimately the profile designer isn't what I'm aiming for.

That takes me back about 30 years. Ultimately the profile designer isn't what I'm aiming for. I want to use a Wii controller/Nunchuck/Wheel to connect by Bluetooth to a Raspberry Pi 2 on the robot which will then send commands to the S-Brick controlling the four PF motors for direction of travel and speed. The fixed position RPi camera will stream low latency video (?) to my smartphone housed in Google Cardboard VR headset. As I turn my head the smartphone gyro will sends its orientation back to the RPi to control rotation. Think of it like driving a car whilst ocassionally looking out of the side window or rear view mirror rather than simply straight ahead. This is purely a hobby poject for me but if you felt you could share some of what you have learned it would be greatly appreciated. I suppose I ought to put up a Wordpress page to document my progress or lack of it as its bound to be messy.Please let me know if you publish anything ?  less

Right now I am still fussing with how to keep Python from freaking out when gatttool fails once in a while. Have to add more code to track errors so I know whether it is really gatttool or the PS3 controller or both. I've used Python plenty, just not as much for error handling and driving other programs.

Is anyone interested in helping to developa Profile for this ? There will need to be some trignometry involved in order to get all four wheels working together correctly. It should be faster than a traditional 4wd vehicl ebut not as strong. Is there a noobs tutorial for Profile development ?
