In this episode, Krzysztof will explain us about using cheap, fast, small and light weight time of flight sensors on drones in outdoor environments.
We will discuss about distances that those sensors can reach, frequency of update, interference between sensors and how to combine rings of sensors. Krzysztof will explain how to get data from those sensors into ROS and how to convert to different types of ROS messages, like LaserScan or PointCloud2.
Selected quote:
“Those sensors are very light and very fast which make them perfect for sensorizing drones”
In this episode I talk to Roberto Guzman who will tell us about how to speed up our robot building by using certified ROS components.
He also talks about how easy he feels that is to transfer results from simulation to real robot, about the ROSCON, IROS and ROS-Industrial.
Selected quote:
“One thing that I’m missing from simulation is to have a less heavy (in physics) simulator that allows the easy simulation of a fleet of, let’s say, 10 robots”

In this episode Martin Pecka will talk about the Tensorflow ROS cpp package, a ROS package he created to simplify the use of Tensorflow within a ROS node and to provide a universal interface to ROS programs, independently on how Tensorflow was installed in the system.
Selected quote:
“The Tensorflow ROS cpp package works as a translation layer between all the ways you can get Tensorflow installed in your computer and your ROS programs”
In this ROS LIVE-Class we’re going to learn how to create a ROS program that uses Tensorflow to recognize captured images from the robot camera, in real time. We are going to use a Gazebo drone simulation that flights over a space and recognizes the objects below it.
We will see:
▸ How to launch Tensorflow with a ROS program
▸ How to use a trained model to recognize objects
▸ How to feed the trained model from images obtained from the camera of the robot, in real time
▸ We will move the drone around and make it identify what its camera is seeing, in real time
Every Tuesday at 18:00 CET/CEST.
This is a LIVE Class on how to develop with ROS. In Live Classes you practice with me at the same time that I explain, with the provided free ROS material.
IMPORTANT: Remember to be on time for the class because at the beginning of the class we will share the code with the attendants.
IMPORTANT 2: in order to start practicing quickly, we are using the ROS Development Studio for doing the practice. You will need a free account to attend the class. Go to http://rds.theconstructsim.com and create an account prior to the class.
