Lego RepStrap

Two axis platform

This is the most compact sturdy two axis platform I have been able to make. It is still not perfect and suffers from some (fairly minor) lash-back problems, but hopefully I will get round to re-designing it soon.

These CAD models were created in MLCad running under WINE in Linux.

Electronics & Motors

I am using generation one (PIC) electronics and some small stepper motors that have been modified to work with lego.
