Driving a robot with a Wii Nunchuck
 

Here's something I've been playing with for the last week or so:

Wow, that's really cool!

Re: Driving a robot with a Wii Nunchuck
 

this is the coolest thing ive seen all day

Re: Driving a robot with a Wii Nunchuck
 

umm, I'm not sure, but...
there isn't an accelerometer on the Nunchuck is there? or are you just tilting the 'chuck for effect?

Re: Driving a robot with a Wii Nunchuck
 

There's a 3-axis accelerometer in the Nunchuck.

Re: Driving a robot with a Wii Nunchuck
 

Both nunchuck and remote have 3-axis accelerometers. The nunchuck lacks the IR camera that gives the remote its pointing abilities.

That is dang schweet!

Re: Driving a robot with a Wii Nunchuck
 

ok, that is WAY cool!!! I have a student who wants to use the Wii controller on the robot. I really need to show him this.

Re: Driving a robot with a Wii Nunchuck
 

Super cool!

I did this with the old control system, but had to use a computer in the middle because we didn't have USB back in the day :)

awwwwwwwesome

Re: Driving a robot with a Wii Nunchuck
 

that's amazing but it gives me a feeling that it'll be hard to control like ways i wounder how a ds lite would work I'm guessing someone would make a program for the R4 and it'll use wi-fi configurations and connect to the router? does anyone actually know how i'm sure it's been done before I'm not planning on using it but it''l be fun to know

Re: Driving a robot with a Wii Nunchuck
 

you guys using that this year? i guess not if it requires an adapter, but it would be cool!

Re: Driving a robot with a Wii Nunchuck
 

We had seriously thought about doing this to drive the robot this season, but the controller uses bluetooth, which is specifically excluded by the rules (at least for this year).

Re: Driving a robot with a Wii Nunchuck
 

The Nunchuk talks I2C, which is a wired communication protocol. The way Dave describes the setup, they have the Nunchuk plugged into an adaptor board which translates the I2C into USB, so there is no wireless involved. It sounds perfectly legal to me.

Re: Driving a robot with a Wii Nunchuck
 

Unfortunately, I couldn't see the video (blocked where I work) or I guess I would have known that:(

That sounds awesome. I'll need to check it out when I'm home. Actually, I had looked at using the normal Wii controller (not the Nunchuck). I don't believe that could be used the same way.

Re: Driving a robot with a Wii Nunchuck
 

I can drive our robot with hand gestures. Push=forward pull=backward etc.

Re: Driving a robot with a Wii Nunchuck
 

yeah, the video was blocked here too. but great idea and concept.

Re: Driving a robot with a Wii Nunchuck
 

Very Kool Dave... I iwshed I had time to even try that out.

Re: Driving a robot with a Wii Nunchuck
 

That is pretty neat, but how do we know you're not using a regular controller off-screen?

Re: Driving a robot with a Wii Nunchuck
 

Because WildStang has a thing for irregular control setups. ;)

Re: Driving a robot with a Wii Nunchuck
 

Our team had thought of this as well, on the topic of intuitive control, but it was decided that the good old joystick shall suffice just fine.

We also passed around the idea for stability/autonomous of using the Nunchuck on the robot with the handy I2C port on the DSC. This idea also faltered, as we came to the conclusion that we do not need that type of sensor inputs for our automagic functions this year.:rolleyes:

Well done Wildstang, that's really neat!

Unfortunately, with the way the I2C support was implemented on the crio, I don't think you can use it to talk to a Nunchuck. The Nunchuck requires that you send a single byte and then read back 6 bytes. The crio only lets you read 4 bytes at a time and insists on sending an address byte before each read. At least, that's what I gathered from reading/using the I2C code in WPIlib.

Re: Driving a robot with a Wii Nunchuck
 

I didn't know wii nunchucks has accelerometers in them haha well wayyyy cool dude:cool:

Re: Driving a robot with a Wii Nunchuck
 

If it didn't use accelerometers, what would it use?

Re: Driving a robot with a Wii Nunchuck
 

Simply fantastic - sounds like a CMP Control Award winner to me!

Re: Driving a robot with a Wii Nunchuck
 

Is this actually being used on the Wildstang bot for competition, or was this just a cool project?

Re: Driving a robot with a Wii Nunchuck
 

You crazy motorola people and your freescale processors... :rolleyes:

Interesting idea to make a USB device have the same report descriptor as the joysticks to fool the operator station.

Cool! :D

Re: Driving a robot with a Wii Nunchuck
 

We couldn't get around the obstacle of "no bluetooth", so we abandoned our "minority report" project. Now we just use it for games..

Re: Driving a robot with a Wii Nunchuck
 

wow, that is cool. can we see the code for accessing it?

Re: Driving a robot with a Wii Nunchuck
 

was that programmed in windriver or labview?
