Some people over on reddit have expressed some doubts about using wiper motors to turn the sphere. Now rather than complain that they’re ‘wrong’ and ‘know nothing’ I should admit they probably have a good point. Wiper motors are cheap, ubiquitous and pretty reliable. Are they suitable for this? I’m honestly not sure.What? Somone on a blog not claiming to be omniescent?? :p

In an ideal world I would have done some calculations before making my site public but I can hardly go dark now the hard questions are starting. However I am going to start looking properly at it. Autodesk Inventor has some great simulation tools to model torque and acceleration… which I have no idea how to use :p Well, I have a vague idea….

So please bear with me, I’ll watch some more tutorials and try to figure it out. I’m actually interested in working out what the power requirements are myself.

Don’t expect a 3DOF demo however, you’ll get a cyber rocking chair in one dimension only and use your imagination for the other two. 🙂
