We’ve made a lot of progress on the design for the three degree-of-freedom simulator, and are hoping to order parts to start the build early next week.
This new design allows for continuous rotation on every axis, although it will require a lot of space to do so.
Rigidity might be tricky on this one. After running the numbers on some worst-case scenarios, we think that the frame itself will deflect less than 0.16″ on the inner axis. The axis bearings may cause more than that, though. And it’s difficult to know how the new drive train is going to perform in terms of backlash and rigidity.
But we’ll find out! The build process will start next week.
