Mecanumbot Ball Following December 10, 2013 No Comments

I have updated my Mecanumbot code to the latest and greatest ROS distribution – Hydro. During the upgrade, I wrote a companion app to publish velocity commands based of of the output of my ball tracker. The result is that the Mecanumbot can follow a red ball around the room! I wrote the ball tracking [...]

Mecanumbot Integrated Lights Test April 9, 2013 No Comments

I’ve finally achieved end-to-end control of the Mecanumbot’s LEDs! The latest hurdle which prevented me from writing the LED code was a RAM limitation on the microcontroller side. The solution involved swapping over from an Arduino Duemilanove with 1KB of RAM to a Seeeduino Mega with 8KB of RAM. The increased RAM also opens the door for me [...]

Quick Manual Control Demo November 12, 2012 No Comments

This weekend I added a wireless Xbox controller to the list of devices I can use to control the Mecanumbot. Before now I’ve been able to use a standard RC transmitter, a computer keyboard, and a Wiimote. I again used the ROS framework to integrate the controller. Built into ROS is a joystick node to [...]

Legorov Teleoperating Robot November 8, 2012 2 Comments

I built this little robot out of Lego this week (see picture.) The electronics include an Arduino, a Sparkfun xBee shield, and an Adafruit motor shield. On the other side of the xBee shield is a linux box running ROS. With ROS I can generated velocity messages from my keyboard or with a Wiimote. These [...]

Starting New Project: The Mecanumbot July 20, 2012 No Comments

Alright. I have decided that I do not have the time or desire to figure out the controls problems that the Ball Bot presents. I really am interested in the navigation and localization challenges that I can work on with a functioning robotic platform. So what I need is a platform that is easy and [...]

Identify Duplos ROS Package November 28, 2011 No Comments

The goal of this project is to “count the Duplos on the table.” The tools available include a point cloud-­‐producing sensor (the Kinect), ROS, the Robotic Operating system from Willow Garage, and PCL, the Point Cloud library. An end goal for this project is to provide some usual information to another agent such as a [...]

The Ball Bot May 4, 2011 No Comments

I’ve started a new robot project! This will be one of the most challenges personal projects I’ve embarked on. I have the following goals: designed to be a flexible software test platform mechanical design from scratch in SolidWorks, manufactured from G10 low level control through off-the-shelve electronics including an Arduino, SparkFun Quadstepper motor controller, ITG-3200 [...]
