Completed integrated CAD and ROS Simulation Environment
Log from Love Elemental
(This is actually as-of Dec 19, 2020)This shows the environment I created that uses python to combine openscad, step file importing, and joint definitions to export to a physics and motor-control simulation-ready model for Gazebo/ROS.It was particularly...

I am a computer vision and machine learning expert with full experiences in tensorflow, darknet, keras, pytorch, opencv and openvino, android, iOS, C#, C++, flask web app, etc. These are my main projects that I did before. - Robot Simulation and ROS...

ROS: a simple depth map using StereoPi
Log from StereoPi - DIY stereoscopic camera with Raspberry
If you use ROS when creating robots, then you probably know that it supports utilization of stereo cameras. For example, you can create a depth map of the visible field of view, or make a point cloud. I began to wonder how easy it would be to use our...

ROS Integration : Finding the Robot Transforms.
Log from Micro Robots for Education
Hello,So progress is quick recently! Last time we saw the robots moving under control from ROS, so the next problem for a proper closed loop system is how do you know your location. The robots do have odometry on them in the form of stepper motors, if...

Speech recognition in ROS with PocketSphinx
Log from Wild Thumper based ROS robot
Current goal is to issue voice commands to the Wild Thumper robot. The speech recognition engine PocketSphinx was chosen for this task because it works with little CPU and memory. Since there does not seem to be an up to date ROS node for Pocketsphinx...

Improved ROS-based architecture for the program core
Log from Zakhar the Robot
I'm about to finish migration to the ROS. Aside small things, architecture seems crystalized. It looks like following:Every block represents ROS-node (except the hardware block). Interaction between blocks is trying to mimic a real brain (as I understand...

Code a ros-control node with Arduino to control servos of the arm
Instructions from An Arduino Arm for ROS, wait a medical usage.

Ubuntu & ROS (Robot Operation System) on a RPi3B+
Log from Droidbot 07 - Wheeled-Quadruped
After reading up on different Linux distros (whoa, that's a rabbit-hole!), I installed and tried a few before settling on Ubuntu MATE. I chose it because it has a large community, lots of support, examples etc and will run on a Rasberry Pi. I preferred...

Creating a ROS Node for Sparki - Part 2
Log from Sparki SLAM
In Part 1, I discussed how I had to drop rosserial in favor of a homespun solution to create a ROS node for Sparki. I developed a communication protocol to talk between a ROS node on a PC written in python and Sparki's microcontroller. I created a slimmed-down...

ROS Integration : Finding the Robot Transforms: Part 2
Log from Micro Robots for Education
Yesterday I showed the computer vision part in isolation, today we have the ROS system doing nearly everything that it needs to do. Joypad -> desktop -> arduino interface -> tiny robot -> Camera -> extract robot positions -> broadcast transforms to ROS....

[Enlightened] Getting Ubuntu installed with ROS, Part 2
Log from Project Hermes
Editor's note: I've opted to format log titles with their corresponding project path for referencing. Previous entry updated. Alright, new attempt now with Ubuntu 18.04 LTS, and the DHCP IPv4 issue is back. Running "netplan try" and then "dhclient -4...

Rhys Mainwaring’s ROS Melodic Software and Simulator for Sawppy
Log from Sawppy the Rover
When I created Sawppy, my first goal was to deliver something that could be fun for robotics enthusiasts to play with. The target demographics were high school students and up, which meant creating a software stack that is self-contained and focused...

Creating a ROS Node for Sparki - Part 1
Log from Sparki SLAM
I've decide to use ROS to get SLAM up and running for Sparki. I may not finish the project using ROS but it's a good way to quickly get SLAM up and running.The first step is to create a ROS node for Sparki. My first thought was to use the rosserial library....
