My Omniwheel Article in D&T Practice

featured-omniwheel-article.png

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 ...

Very cool Omniwheelchair

2012-07-29-21.16.10.jpg

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 ...

Skittles on the Threshold

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 ... Read More »

Preview of a new Robot: Skittles

2012-02-24-20.56.20.jpg

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 ...

CIMG1145.jpg

“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 ...

Sometimes you win…sometimes you get omni-humped.

Omnihump

I was working on an omniwheeled robot last night, trying some code that would ensure the vehicle would go straight even if the motors were not perfectly in sync.  Unfortunately, there seemed to be a bit of a bug in the code which lead to some pretty erratic behaviour. So as you can see, not all of my projects are ... Read More »
