Data visualization: global view of blog posts relationship

As stated on a post where i talked about using tf-idf to detect similarity between two blog posts, my blog is just a bunch of posts sorted by date, no category, no fancy features like user interest tracking, post ranking, etc. I usually work on many different domains (robotic,

sysmond: Simple service for (embedded) Linux system monitoring

Working on my DIY robot software (Jarvis) in headless mode, i came across a situation where i needed to monitor the system resource such as CPU, battery, memory, network and temperature to measure the "greedy" of my robotic application. Furthermore, as the robot was battery powered, battery safety

Jarvis Arduino firmware

This post is the follow up post of the previous JETTY: Jarvis Serial to ROS-2 Transport Layer post. The arduino firmware on the one hand implements the JETTY protocol for communicating with ROS and on the other hand takes care of all low-level hardware communication including: * Reading of

JETTY: Jarvis Serial to ROS-2 Transport Layer

My ROS based DIY robot( presented in the previous post) uses the NVIDIA Jetson Nano for high level robotic algorithms with the ROS 2 middle-ware. The Jetson is connected to an Arduino via a serial link for low-level hardware interaction and control. As the Arduino is used for

Jarvis: The DIY robot

It has been a while since i started to build an upgraded version of Dolly, my first DIY ROS based robot. This upgraded version is named Jarvis. Changes from the previous version: * Hardware: * The robot is now use tracks instead of wheels * Jarvis footprint is bigger and has more room
