A collection of ROS packages and Arduino programs to handle miscellaneous robot tasks and system management. If you are a reader of my book Practical Robotics in C++, you will almost certainly find some useful tools here as example for how to code some things we didn't get to cover in the book.
If you find this package useful, consider supporting maintenance, upgrades, and development of new robotics tools and tutorials with a cup of coffee: https://www.buymeacoffee.com/practicalrobot
I've created a lot of tools over the years, but have mostly embedded them in other programs. I thought it was time to start separating them to make them useful for generic robots. More will be added as I have time to make tools I use within my custom robots more generic.

The RPLidar's motor is always running by default. This node allows for the automatic starting and stopping of the RPLidar motor when certain nodes are started or stopped (Default are rviz and move_base, but user-settable). See documentation here: rplidar_motor_control
This is a pair of programs that facilitate the control of relays for a ROS (Robot Operating System) robot via an Arduino. See arduino_ros_relay_control
encoder_tick_pub.ino is a ROS (Robot Operating System) publisher node that runs on an Arduino and publishes an std_msgs::Int16 (-32,768 to 32,767) wheel encoder ticks for both left and right wheels. Works with quadrature encoders. See quadrature_encoder_tick_pub
A utility node to allow different geometry_msgs::Twist messages to have different priorities. If two or more are published at the same time, only the message with the highest priority is republished in order to avoid two node "fighting" for control of the robot. See documentation here: cmd_vel_prioritizer
Please use the issues and bug reporting system for bugs and feature requests. With many projects, a job, a family, I can't promise to get to feature requests very quickly, but am definitely listening for feedback to make improvement and will prioritize bugs. I am open to pull requests if you'd like to contribute. I can be contacted by email at lbrombach2@gmail.com.
