Fixing Functional Problems in URDF
Log from Phoebe TurtleBot
Once I had a decent looking URDF for Phoebe up and running, I added it into the Phoebe launch files and started working on the problems exposed by putting it to work. The first problems were the drive wheels. Visually, they were stuck at the origin and...

Using Matlab for Object Tracking
Log from Bobble-Bot
Recently I received some feedback from a few of our users requesting a Matlab sample project that can communicate with Bobble-Bot. This seemed like a reasonable enough request, so I released a new Matlab interface for Bobble-Bot last night. I'm...

Design #2: Turtlebot-like test frame
Log from MORPH : Modular Open Robotics Platform for Hackers
For the next step, I wanted the robot to be controllable from ROS. I changed the initial design to be more Turtlebot-like to be able to hold a laptop running ROS.Changing the frame was the easy part, most of the work has gone into creating the ROS integration....

Phoebe The Cartographer
Log from Phoebe TurtleBot
Once odometry calculation math in the Roboclaw ROS driver was fixed, I could drive Phoebe around the house and watch laser and odometry data plotted in RViz. It is exciting to see the data stream starting to resemble that of a real functioning...

On the road again!
Log from "Tenacity": Yet-Another-Sawppy-Project
Tenacity is back on the road!(carpet), fresh from what turned out to be an almost 3 month(-ish) refit. A good bit of consulting work came barrelling out of nowhere right after the start of the New Year, so I've spent most of the past couple months...

LIDAR Installation Completes First Draft
Log from Phoebe TurtleBot
With the motors connected to Roboclaw, their direction and encoder in sync, and PID values tuned, Phoebe can be driven around via ROS /cmd_vel topic and report its movement via /odom. However, Phoebe has no awareness of its surroundings,...

Applications
Log from A Helium-Based, Affordable Robotic Airship
As discussed, the developed platform has a cost of 90 USD. If we include also the recommended balloon type (4 USD) and the initial filling cost (16.5 USD), the total cost of the airship comes to 110.5 USD. This is comparable to alternative indoor blimp...

Toasting traces and board layout
Log from Open Rover
I finally got around to hooking up the battery, board and motor together. I expected fire, smoke and failure and I got it but not in the manner that I expected. I thought that the fets would fail because they have been the failure points in the past...

Source code morph stack
Log from MORPH : Modular Open Robotics Platform for Hackers
I've linked the main repository containing the source code for the morph stack for use in ROS. The stack consists of separate packages, each have their own repository but are linked as submodules from the main repository which is linked. morph_bringup...

Real-time Motion Planning with CollisionIK
Log from Crash
Motivation One major barrier to a fluid creative workflow with robots is the often stilted sense-think-act loop. Every time through the loop the robot first gathers information about the environment, crunches the numbers to generate a plan, and then...
