Sriram Narasimhan’s research team are shaking things up in the Civil Engineering Structures Lab at the University of Waterloo. The research, which is led by Ph.D Candidate Kevin Goorts, is developing a new mobile damping system for suppressing unwanted vibrations in lightweight, flexible bridges. Whereas damping systems are often permanent fixtures built into the bridge, their system is designed to be adaptable, autonomous, and better suited for rapid, temporary deployment.
The Arduino family of micro controllers has quickly become a go-to board for hobbyists due to its ease of use. Often times roboticists must create communication protocols to allow their embedded hardware to communicate with a computer. One of the most powerful aspects of ROS is that it can communicate with a large variety of hardware. That’s where rosserial comes in! Rosserial is a general protocol for sending ROS messages over a serial interface, such as the UART on Arduino. This allows you to easily interface any sensors attached to Arduino into your ROS environment. Read on to learn more!
In the previous ROS 101 post, we showed how easy it is to get ROS going inside a virtual machine, publish topics and subscribe to them. If you haven’t had a chance to check the out all the previous ROS 101 tutorials, you may want to do so before we go on. In this post, we’re going to drive a Husky in a virtual environment, and examine how ROS passes topics around.
