2020.08.03. Working on a human-robot interaction system

It was finally published in journal Microprocessors and Microsystems. Available online 21 July 2021 (DOI, draft).

2020.07.30. Supporting Turtlebot2 under ROS Melodic and Ubuntu 18.04

Turtlebot2 is no longer supported on ROS Melodic, so it is necesary to use external drivers to make it work.

Firstly, I get Turtlebot2 motors to work using the code of this repository.

Secondly, the installation of Asus Xtion is quite simple since OpenNI2 is fully supported by ROS and the precompiled packages are available in the official repository. As can be seen in the picture above, the rgbd images are tested using the package rqt:

sudo apt-get install ros-melodic-rgbd-launch ros-melodic-openni2-camera ros-melodic-openni2-launch

roslaunch openni2_launch openni2.launch

rqt

And finally, the RPLidar is also officially supported by ROS, using the rplidar_ros package:

roslaunch rplidar_ros view_rplidar.launch

2020.05.26. Testing a new sensor: BME680 Breakout by Bosch

It contains temperature, humidity, barometric pressure, and VOC (Volatile Organic Compound) gas sensing capabilities. It is connected to the Raspberry Pi board through the GPIO ports and it can measure humidity with 3% accuracy, barometric pressure with 1 hPa absolute accuracy, and temperature with 1ºC accuracy.
