There were a lot of people from DLR (Deutsches Zentrum für Luft- und Raumfahrt) at iSAIRAS. I spent some time with a group who were working on the "DLR Crawler" which, apparently, has been cobbled together out of the "DLR Hand". I had high hopes of this, with visions of this disembodied hand crawling about on the surface of Mars. In reality, the DLR Crawler looks a lot less like a hand than you might expect.

They were looking at the use of stereoscopic vision to make assessments of the roughness of any terrain the crawler had to traverse and plan a route and modify its gait accordingly.

The DLR crawler people (looking remarkably smart) showing off their demonstration set up.
