Using Arduino to add sensors and actuators
Arduino is an open source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
The following image shows how an Arduino board looks:
ROS can use this type of device with the rosserial
package. Basically, Arduino is connected to the computer using a serial connection, and data is transmitted using this port. With rosserial
, you can also use a lot of devices controlled by a serial connection, for example, GPS and servo controllers.
First, we need to install the packages. To do this, we use the following command lines:
$ sudo apt-get install ros-kinect-rosserial-arduino $ sudo apt-get install ros-kinect-rosserial
Then, for the catkin
workspace, we need to clone the rosserial
repository into the workspace. The rosserial
messages are created, and ros_lib
is compiled with the following command lines:
