    The Pneuma-Snatcher

    NXT, ROBOTC, Robots, Sensors March 21, 2011 17:44 9 comments

    The Pneuma-Snatcher is a very ugly robot based on the very nice looking Snatcher, designed by Laurens Valk. I used the two valve kits that Mindsensors sent to me a week or so ago.  They work very well for controlling the pneumatic valves.  If you hook them up to the […]

  • Rotacaster One-Kit Omniwheel Program Update

    NXT, Robots January 6, 2011 12:00 2 comments

    I made some updates to the line following program for the Rotacaster One-Kit Omniwheel robot.  This version 2.0 allows you to adjust the Gain and Power variables by turning the back wheels back and forth.  When you’re happy with the values, you can hit one of the bumpers and it’ll […]

  • Rotacaster One-Kit Omniwheel

    NXT, Robots December 20, 2010 21:16 7 comments

    As I was building one of my previous omniwheel frames, I wondered if I could rebuild it using nothing more than the parts that came with an NXT 2.0 Retail kit and three Rotacaster omniwheels.  After a few hours I came up with this: Quite nice and a pretty stiff […]

  • Another Omniwheeled Robot

    NXT, Robots December 12, 2010 11:00 4 comments

    Earlier this week I received another package from Rotacaster with some more wheels for me to test and play with.  These ones had new molded hubs, instead of the white 3D printed ones. The grip on the axles is much better now and they’re still working on making them even […]

    This is Apollo, the smallest NXT based line follower I’ve ever made.  It’s loosely based on A-Maze-Ing, which I designed and built quite a while ago. Apollo is equipped some pretty cool stuff: The new Mindsensors Numpad A Mindsensors LineLeader sensor Two Rotacaster wheels The program in this robot is […]

    This is my current project and the robot I’ll be taking to Lego World.  Tammy took these pictures for me.  Click on them to see a much bigger version. It has 2 Zamor canons, 4 Rotacaster wheels, HiTechnic Gyro and Acceleration Sensors and a Lego Sonar sensor. It’s programmed in […]

  • Things That Go Bump in the Hall

    NXT, ROBOTC, Robots, Sensors September 26, 2010 13:37 25 comments

    My next project with the omniwheel is to have it react to bumping into things that it encounters on its journey.  I want to use the HiTechnic Accelerometer to do it, the Mindsensors one is currently being used in another project. I’ve been racking my brain for about 2 days […]

  • Rotacaster Minifig Vomit Mobile

    NXT, Ramblings, ROBOTC, Robots September 22, 2010 11:10 2 comments

    The “Minifig Vomit Mobile” is what my friend Marc-Andre called the omniwheel I took the video of.  I felt that in order for that name to be more accurate, I had to add a minifig to the robot, so here he is, on the left.  Unfortunately, this one has no […]

  • Taking the Omniwheel for a Spin

    Experiments, NXT, Robots September 21, 2010 16:05 9 comments

    Literally. The omniwheel is capable of going in any direction you want, it can also rotate on the spot.  So I thought, why not combine the two and make it rotate and move?  After picking Brian Davis’ sizable brain about using a gyro as a means to calculate a heading, […]
