Hello ROS users,

I have released a new package for the Element microcontroller made by cmRobot. Details and source code can be found at:

Documentation: http://www.ros.org/wiki/element
Source: svn http://pi-robot-ros-pkg.googlecode.com/svn/trunk/element

(The source link should appear on the Wiki page on the next indexing.)

Features of the package include:

Support for a wide variety of commonly used sensors including sonar (Ping, MaxEZ1), infrared (Sharp GP2D12), temperature, current, and voltage (Phidgets), speech (Devantech SP03), compass (Devantech CMPS03), as well as generic digital and analog sensors.
Onboard PID controller and dual H-Bridges for driving a differential drive robot
One bipolar stepper motor
Support for controlling up to six hobby servos
Sensors are polled using a multi-threaded queue and can each run at their own rate
Connects to a PC or SBC using USB, XBee or TTL
