One of my many Lego NXT project ideas is to build a Rocker-Bogie system similar to the Mars Sojourner, Spirit and Opportunity rovers. It turns out a similar mechanism is ipresented by Brian Bagnall in his book titled Maximum Lego NXT: Building Robots with Java Brains.
While I wait on that book to move from […]
As you can probably tell, I like the holonomic drive as a platform for robotics. Be sure and take a second to check out this version of the platform with a very simple but effective wheel design:

Here is an idea I have been playing with for a little while. Instead of simply doing a car with regular steering, I wanted to try a split chassis design where the front of the car rotates in the direction you want to turn. Here are two attempts, but I abandoned any further design after […]
The other night I was researching building a balancing Segway like robot with the Lego Mindstorms NXT kit. I wanted a robot that could balance on two wheels and could move forward and backward. I also wanted the robot to recover when “pushed”.
I was familiar with Steve Hassenplug’s Legway built on the Lego RCX […]
I updated my Lego NXT holonomic platform a bit. The main changes revolved around the orientation of the motors so I could get true 360 degree movement.

I have been working on a few different designs for a holonomic drive robot. A true platform like the other killough platforms made from Lego would probably contain wheels that rotate differently, but I wanted to publish this design because it is interesting.
I tried two different versions that you can see in the movie below. […]
If you look in the navigation on the right hand side on my home page, you will notice a new goodie. I integrated an eBay search script. Check out the post the have fun searching eBay for Lego.

I have been working on creating a new Synchro Drive for the turntable that comes with the Lego Mindstorms NXT kit. I have the basics worked out but I need to refine it a bit so I de-constructed it on video so I can start over.

My NXT arrived today so with the help of the kids, we build the first level robot and had some fun with programming.
The Lego NXT Robotics Toolset: 32-bit Processor, More Memory, USB Connectivity to the PC for programming, BlueTooth so your phone can control the robot, Bump Sensor, Light Sensor, Sound Sensor, and RangeFinder Sensor. This is the RCX upgrade we were hoping for…downside, not backward compatible (so what). You want more details? Check out the Lego […]
