In lots of aspects 2017 was definitely interesting. I finally feel I settled in the Geneva area and can’t wait to see what happens in 2018!

The Port Humanitarian Hackathon - Report

I was very fortunate to be selected as one of the participants of The Port hackathon. In this post you can read about the experience and what our team came up with during one month of preparation and 3 days of hard work.

Enum flags in C# are life

For the 5 years I’ve been working on and off with C# I’ve never encountered enum flags. Until yesterday. I thought the concept would make a great blog post so here it is!

As a continuation of 1PPM challange I dived into uncharted territories of web development (something I was actively trying to avoid throughout my life so far).

In this post I will briefly present my (only partially unwarranted) worries on web development as well as mention the courses I learned from and possible way forward.

My March 1PPM project significantly differs from all previous ones as I dedicated it to learning Robot Operating System (ROS).

The two books I almost read during this period are:

  • Mastering ROS for Robotics Programming
  • Programming Robots with ROS

In this post I will briefly describe my experience with aforementioned books (which in one particular case was quite short!)

Assign a static USB port on Linux
Image source:

Quite often I found myself needing static device names in Linux, especially when using ROS. As an example imagine having two sensors of a same type that yo connect to your PC. Now, if you don’t map your ports in any way you might end up with devices being mapped to /dev/ttyACM0 and /dev/ttyACM1, depending which one was connected first.

Let’s say your sensors are at different positions on the robot. If you want to make sure that you are using the proper device in your code you can either:

  1. Unplug and plug back the sensors again until you get the names you want
  2. Assign a static name to a port and be done with it

If you want to learn about the option 2 then read on.

Otherwise keep playing with your cables!

UAV haptic control using Novint Falcon - pt 2

I consider the second and final part of the falcon project as finished from 1PPM perspective. Most of the project I already described in the previous post

Short summary of achieved results:

  • All the work done and test for Px4 SITL(jmavsim)
  • Mavros is used to talk to pixhawk (or SITL in this case)
  • Falcon is not suitable for flying real models (it isn’t reliable enough)

Without further due, here is the video showing the proof of concept in action:
