A little while ago I was asked to write a robotics article for the British Design & Technology Practice magazine.  I chose to cover the basics of programming a LEGO MINDSTORMS NXT omniwheel based platform, and the mathematics behind it.  ROBOTC is used as the programming language, but I am sure the principles apply to other programming environments, too.  Although, I ...

Simon Burfield, a.k.a. Burf has made a super cool model.  By model I mean chair and by chair I mean omnidirectional wheelchair. Oh and it’s life-sized, too.  Yeah, it is capable of handling no less than 90 kg!  I saw a video of an early prototype a few weeks ago but this new one is even better-er! Some facts: It ...

My robot Skittles is a big robot; he’s probably one of the biggest wheeled robots I’ve made so far.  When the Mindsensors PSP-Nx-V4 came in last week, I knew I had to make it remote controllable. I finished up the last bits of the driver for the new sensor yesterday and so this evening I cobbled together some code to ...

Last Saturday, Laurens and I were asked to give a LEGO Mindstorms NXT demo at the Dutch Robocup Junior championships.  We had our table setup on the second deck, right along the path to the actual arena. There were plenty of robots there but one in particular caught my eye.  It was the Talentenclub’s Talentenbot.  It was the only one ...

This is a quick video I shot with my mobile phone of a new robot called Skittles. Why did I call it Skittles, you ask?  Well, it’s got all colours in the rainbow in it because I simply don’t have enough bricks of one or two colours to build the whole thing uniformly.  So I figured I may as well ...

“Omni all the wheels!” That was my first thought when I received these new Rotacaster 125mm omniwheels.  They’re fantastic looking and HUGE, about 3 times the diameter of the 43mm ones that are being sold now.  They have some pretty impressive stats; they can handle a load of more than 100 kilos each!  I am not sure when they are ...

I’d like to wish all of my readers a very happy and prosperous 2012. 2011 was a big year for my blog and NXT-sensor land.  I moved from a hosted WordPress blog on wordpress.com to my own one on HostGator.com.  I’ve never been happier about a hosting company.  We had some major issues with our previous one (Hostway) which hosted ...

As per request, here are the ideas of the winners.  I have copied and pasted (most of) the information from the original mails and edited it slightly. Benoît Genest: An omniwheeled container handler. In almost every Intermodal port, you can find Container Handlers (or Reachstacker) . These are usually 4- wheeled telehandlers featuring a specially adapted claw to handle containers ...

Man, this was really, really difficult.  There were some really good submissions but in the end there could only be three winners.  So without further ado, the people who will be receiving a set of these wheels are: Simon Burfield Benoît Genest Brian Bachmeier Congratulations to the three of you and I really hope you will share your inventions with me ...
