Hello everyone! :) In the title of this blog I mention that it is also about robotics. However, and to be honest, I've realized that I haven't posted much stuff about it. I hope to fix that in the following posts since recently I've finally finished some robot projects that I have been doing in the past months. Unfortunately I can't publish them yet. Maybe in a month or two :) Anyway, I'll start with a simple post regarding a simple but very useful part for small robots: ball casters!
You can buy ball casters from several robotics shops online and they're not the most expensive thing on earth. However, there are other options that can be cheaper and will save you from the waiting until you receive the ball casters that you may order from shops online. Some of the options fit in the spirit of Green Robotics, which is the idea of reusing and recycling everyday things to make robots. I'm going to show you three options that may suit your needs :) .

I'll start with the option that I think to be the best of the three that I'm going to talk about. See the shiny metal balls stuck in a white plastic piece? They look really good, don't they? :)
