Here’s a little teaser of a current project that I’ve been working on.
If you take a delta robot and replace the parallel linkages with the a pair of parallel wires wound over motor pulleys then you get a robot that can scale up to giant size.

To whet your appetite for giant indoor cranes; here’s a couple of videos of the crane as it was set up at the OGGCamp 13 Open Hardware Jam:
