ESA published a couple of amazingly detailed illustrations of the Exomars rover.

Just noticed the wheel rims 'sag' on the portion touching the ground like a deflated tire. Was it always designed that way or did they notice Curiosity's issues with sharp rocks? What are the advantages compared with rigid wheels? This page has some info that it's for navigating dunes but is slightly vague on how it works.

Deformable wheels have the advantage of increasing the contact surface therefore increasing traction. Increased traction will decrease sinkage and will get better performance (less slip). Not always and not in all conditions, but it is a nice feature. Apparently the ExoMars rover will also have active suspension which will allow to transfer load between wheels, which is nice to have under difficult situations. It would also allow to change the vehicle attitude slightly, which is a bonus when driving a solar-powered vehicle.
Both the deformable wheels and the active suspension add mechanical and software complexity. If ESA actually manages to bring it to Mars, I'm very happy and humbled by their accomplishment.

Aram Dorsum 2
Click thru for video... Features ExoMars rover to scale. Distilled from MOLA/HRSC x5/CTX x6/HiRISE x3 Here are some stills illustrating the rover & ridge a little better than the video managed. -------------------- |

Here is a 1.8 gigapixel render of the Aram Dorsum HiRISE dataset...
And here is the interactive version over at Gigapan Can you spot Exomars Rover? -------------------- |

Here is a model over at Sketchfab The VR avatar is about 6m tall due to hard lower limit on Sketchfab avatar size related to volume of the scene. Next version will be cropped smaller to accommodate correct avatar scale. -------------------- |

Everything you ever wanted to know but were afraid to ask about the PanCam Instrument for the ExoMars Rover.

Everything you ever wanted to know but were afraid to ask ... ExoMars Rover[/url]. Darn, still using 1024x1024 camera sensors. On the plus side, it should be easy to add ExoMars pancam capability to AlgorimancerPG, if there's any interest, and if I can get back up to speed on Visual C++ (I've been focused on R for the past decade) -- I'd be happy to open-source that project, if anyone would like to take over. |

QUOTE The team intends to make images available via ESA in near real time for outreach purposes as appropriate. I know it's really early, but could this signal a dedicated automatic pipeline for raws or just an image of the day like Rosetta? Gosh, it would be weird after NASA spoiled us for a decade-plus to suddenly not have daily panoramas and maps of a rover's traverse. |

For the benefit of those unable to attend last month's SPA meeting in London, here is the video of the talk about ExoMars 2020, given by Prof Andrew Coates:

Sorry to reply to an old post, but I'm on the ExoMars PanCam science team, and just saw it. If you were to make the project open-source at some point in the future, then I'm pretty sure that I could find somebody interested in updating it. Cheers, Pete |
