I do not understand your seemingly loose dealing with dimensions
Each object has 4 dimensions at any one time
X; Y; Z ;and t (t being when it was there)
How do you get 6 or this ++ idea? What exactly do you mean by that?
Probably, you are referring to project #2 in series , which is "Optical Magnet". There is a quote from project description:
This version of hardware/software system design capable to track object in 6 - D ++ space:
* - Linear motion along X, Y, Z coordinates (3D);
* - Rotation around fixed axis (6D);
6D was brought to stress tracking rotational speed, and ++ acceleration capability. More on Wiki:
The position of a rigid body in space is defined by three components of translation and three components of rotation, which means that it has six degrees of freedom. http://en.wikipedia.org/wiki/Degrees_of_freedom_(mechanics)
Though I stopped developing "Optical Magnet" now.
Visual Navigator (#3) is supposed to be "low price" Roomba alternative, there is no tracking / 6D and others features from previous projects.
May be it was not a good idea to include all 3 projects in one topic, but IMHO, as they really close in hardware and conceptually, I decided not to start separate thread.
