ROS finally
Log from Getting started with ROS
In this project log I will describe how I got my distance sensor assembly to work with ROS and how I displayed the scan data using RViz. In addition to this project log I prepared a short video showing the distance sensor assembly performing a 360°...

First Foray into ROS
Log from OSCAR: Omni Service Cooperative Assistant Robot
Now it was time to tackle some of the software (talking about codes running on the computer not the firmware) side of things. The very first thing we did was to load our under-powered PC (it is a 32 bit system by the way) with the latest version of Ubuntu...

ROS Navigation Stack Setup
Log from Phoebe TurtleBot
Section 1 “Robot Setup” of this ROS Navigation tutorial page confirmed Phoebe met all the basic requirements for the standard ROS navigation stack. Section 2 “Navigation Stack Setup” is where I need to tell that...

ROS Integration take 2.
Log from Micro Robots for Education
Hello again.ROS: Did I do this before?ROS: Robotic Operating System is a key part of modern robotic research. The glue that lets academics and industrial system designers package their work in a way that is easy to share and stick to other modules. If...

ROS Notes: Map Resolution
Log from Phoebe TurtleBot
Now that I’m driving Phoebe around and mapping my house, I’m starting to get some first-hand experience with robotic mapping. One of the most fascinating bits of revelation concerns map resolution. When a robot launches the Gmapping module, one...

[Enlightened] ROS Tutorials, Part 1
Log from Project Hermes
The first few ROS tutorial pieces have gone well. I'm getting a feel for catkin (the build manager within ROS). Reminds me of PHP's artisan manager for Laravel.I've gotten to the point in the tutorials where apparently I will need some manner of Xwin...

Radiation Counting - Ready for ROS
Log from GeigerROS
After we got a single radiation detectors to work with an Arduino Nano, the next step was to connect three of them to the board and write a sketch that provides the data as ROS topics using the rosserial package. Instead of using a breadboard to connect...

Johnny-five/nodebots vs. ROS
Log from Autonomous rover/robot dog
To celebrate #PiDay 2017, I decided it was time to investigate options for open-source robotics libraries and protocols that I could use with my Raspberry Pi 3 (and Arduino Mega). There's still a part of me that wants to just keep exploring and building...

ROS Navigation Up and Running
Log from Phoebe TurtleBot
I’ve been making progress (slowly but surely) thorough the ROS navigation stack tutorial to get it running on Phoebe, and finally reached the finish line. After all the configuration YAML files were created, they were tied together into a launch...

Reimplemented the Reptile demo with ROS!
Log from Zakhar the Robot
Half-milestone. What's new for now: Brand new moving platformUnited sensor/face platformRaspberry Pi 4New ROS-based application architecture Updated face module with stabilized voltageUpdated cable system with 8-pin connectorsStable (finally)...

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...

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...

[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...
