It appears the I-Swarm robot project has produced some fully-integrated and apparently functional micro robots -- almost four years after we saw the initial conceptual videos appear online.  What makes these robots so impressive is the level of integration; they possess a micro-step locomotion mechanism, a solar cell, custom IR communication modules, and an ASIC (custom silicon circuitry) all in a very compact package.  I've quite impressed by the pictures and videos (embedded below).  Since I-SWARM stands for "Intelligent Small-World Autonomous Robots for Micro-manipulation", I'm a bit perplexed by the lack of manipulation capabilities.  They do have a small piezoelectric-driven cantilever arm in the front, but it currently doesn't seem as capable as AFM tips employed by the MiCRoN project's micro robots.  Perhaps, as the PhysOrg article notes, they just need additional funding -- appropriate for such quality engineering and top-notch research.
