SRI is developing new technology to reliably control thousands of micro-robots for smart manufacturing of macro-scale products in compact, integrated systems.
I find this very interesting. The possibilities are amazing, including shrinking the factory for delicate fabrication. Perfect for new meta materials like Graphene. Integrate this with a series of small 3D printers and you could have a custom table-top factory to assemble complex systems will minimal infrastructure at a fraction of the cost.
