Content in “bluetooth”

So I started using this site a couple weeks ago. I put a project up, sort-of finished it, bugged some guy for some cad files, then stopped posting... That's lame though, so here is some misc. stuff!

I made a "quick" and very wobbly arm to experiment with Arduino, servos, and kinematics. It took some time to stick it together. The little servos I'm using don't have many mounting options, but I came up with some interesting ways to mount them.

Bluetooth, java, Linux - seem to be working together in harmony now. Some things I learned along the way regarding the RXTX java library and Linux com ports in general:

By default, only the root user has access to read/write the serial ports on the system. So if I take the sample code from RXTX I've attached called FindPorts.java and run it from the command line with my user account it will not list any ports. This code was lifted straight from the RXTX site. I've packaged it in a jar file for ease of use from the command line:

Back to work on the Ardbot. I've decided to build my control panel competely in java/JavaFX on Linux. One challenge was getting my Bluetooth connectivity going on Linux with this configuration:

• Kensington USB Bluetooth dongle on Fedora 11 PC
• Sparkfun  Bluetooth modem on robot

My goal will be to control the robot from a gamepad controller attached to the PC, wirelessly over the Bluetooth link.

This is an Open Source, Collaberative project blog.

The aim is to use commonly available Bluetooth USB dongles to enable a PC to control a free roaming robot.

In my case the missing link which I have been trying to get working since about 2001.

The idea is to have an autonomous PC controlling the robot remotely (WITHOUT A CONNECTING WIRE ), so that I can test some rather radical Artificial Intelligence ideas that I have.

These are the source files related to the setup I mentioned in CTC's post about wireless serial com.

Reposting info on the setup just for ref.

Alrighty, ctc, got the rig working. The setup is the following:

<ir beacon> transmitting byte sequence from 1-9

<relay station> picaxe 8m with ir receiver showing correct data in the debug window.

Transmitting the byte sequence received from ir beacon via bt to my desktop running the processing code.
