Nunchuck controlled robonova

[Voelker]

Hi,

there is many projects using the nunchuck connected to an arduino board to control different kind of application. I have managed to connect a nunchuck to an arduino and create a connection to my RN-1 using a bluetooth. I am now able to send command to my robot to do continuous walking, side stepping, turning, backward walking using the nunchuck analog stick, right tumbling, left tumbling, sitting using the accelerometer and buttons. I will improve the programm to perform attacks using the accelerometer and buttons. This seems to be a pretty good method to control the robonova, it has less button than a PS2 controller, but the accelerometer gives a lot of possibilities. I will post a video as soon as possible

I am attempting the same concept of control using an Arduino and two triple axis accelerometers. I had the puppeteer strings and t-handles in mind but wireless obviously. My biggest problem is finding the time to complete anything. I only have one BlueSMiRF Gold so I have been pushing the control signals through the Arduino to a Processing app which then connects to the RN through the Bluetooth in the PC. I should have spent the money for a new SMiRF and maybe I would have been further along. Do you have a video or Arduino/Wiring code to post??

I can now move the robonova around using the nunchuck analog stick (continuous walking, right & left shift, right & left turn, backward walk ...). Combination of accelerometer and button gives another kind of control (right & left tumbling, sitting ...). Response time is quite fast, but the basic code doesn't allow very quick reaction. I ll post a video, wiring code and basic code as soon as i can.

here is a video of the nunchuck controlled robonova, i'll post the wiring code soon ... The video has a poor quality but my mobile phone was the only thing i could use.

congratulations!
great work. please post some technical details about your setup.
Did you use an Arduino with bluetooth or separate modules ?

I found this tutorialabout linking Arduino with a Wii Nunchuck

I didn't use the arduino bluetooth board but i made a custom shield to link the arduino with the nunchuck and to connect a bluesmirf on the arduino's serial port. Most of the post about the arduino + nunchucks says that nunchuck is 5 volts tolerant but i have included on the shield a 3.3v regulator. The robonova also have a blusmirf module, and the arduino's bluetooth module is configured to connect to the robonova's module. For the arduino is used a modified version of the code provided here http://www.windmeadow.com/node/42. The only difficult thing is on the robot size, has the ERX macro is not blocking. I am gonna post the wiring code soon.

Hi Voelker,
Do you have code to make Nunchuck that connect MR-C3024?
thanks
