To test the mechanical integrity of my new design I set about cutting the pieces, not out of cardboard but with MDF.
Using stepper motors I was able to ascertain the structural compliance of the design and exactly what parts I would need to build a larger version.
As you can see from the above photo The axle is made up of two bearings sandwiched between two nylock nuts with a timing pulley that holds the timing belt in place. We have four angle brackets to keep it secure and downward facing stepper has a mounting hub attached to it to spin the body horizontally.
Above we have the fully assembled small scale version. This version was a success, the platform moved with ease and the body did not sway. I shall now move on to scaling the design up in size to test the limits of its stability.
