Read More »My Omniwheel Article in D&T Practice
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.

I finished up the last bits of the driver for the new sensor yesterday and so this evening I cobbled together some code to ...

“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 ...
Read More »Sometimes you win…sometimes you get omni-humped.
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 ...
