Re: NXT and Raspberry Pi

Look on kick starter for something called Brick Pi. It's a project to turn a rpi into a new higher power NXT control block. Using that you could run the NXT motors and sensors directly from the pi, and just SSH into the pi over wifi for control.. For video, just use the pi camera and something like ...

Re: Can I do this with a Raspberry Pi or Arduino?

I just ordered one of the Alamode units. As others have said, the Pi is great for some things, the Arduino for others. The alamode is nothing more than an Arduino that is able to be stacked on top of an Rpi via the GPIO pins without having to tie up a USB port to hook them together. You could do exa...

Re: ROS on RPi

Well, the thing is, we can keep the raspian up to date ourselves no problem using RPI-Update and apt update/upgrade. It's the ROS version that's going to be a pain. Basically, somebody is going to have to get it built from scratch every time there's a new release. Personally, I just want Fuerte for ...

If you install rpi-update, and do the whole sudo apt-get update + sudo apt-get upgrade, it will get whatever version Jeremy used to start with up to date.

Hi folks, I wanted to let you know I'm sharing a new SD card image with ROS Fuerte core libraries and 95% of the ROS Desktop Install, + rosserial & rosserial_java stacks and Arduino pre-installed.

Re: USB redux

Or 7 funky ones... In my case it's the other way around... I have a brand new 4 port powered Hub that whenever I use it the Wifi adaptor drops out constantly. Then I have a like 5 yr old 7 port DLink hub and it works rock solid. If I take away the hub and just use the Wifi adaptor plugged directly ...

Ok, seems like it's still a power related issue. I switched to a different USB hub I have and haven't had any problems since. It's an older Belkin 7-port F5U259-ME.

Hey gang... After seeing the recent story on the front page about the RPi controlled Roomba, I decided to dust off my old 500 Discovery series, and my old USB Roostick+cable.

Hate to say it, but you're NEVER be able to do what you want to do without learning and dealing with at least a LITTLE of that stuff.... There are TONS of motor controllers out there, but you have to understand at least a little of the electronics to know how to go about hooking them up and controll...

Re: ROS on RPi

So, what do you think the impact will be of the RAM boost coming on the RPI's? I haven't done much (ok, anything) with ROS on the RPI other than run through the basic tutorials, so just wondering if having the extra RAM will enable us to run more of the various stacks/packages or help with things li...

Jeremy, I could be wrong, but I thought that Rviz only works on Nvidia gfx systems. I know we have had issues at work in the past where you can start Rviz but you only get a black window if running on a non Nvidia gfx card. In general, the limiting factor with Rviz is the need for good openGL suppor...

Re: ROS on RPi

From what I've read in the other thread on here about getting the Kinect working, the Xtion works better, but I could be mis-understanding what they're saying. If nothing else, the XTion uses WAY less power and only ties up 1 USB, not USB+aux power, so less cables to deal with, and it's smaller and ...

Yeah, I've had issues like that in the past. It seems like the ROS repositories have a tendency to be in flux at times and their servers changing. Usually means you just have to try again later.
