mars rover - slightly OT

"According to Chris Draper, Astrium's ExoMars rover vehicle industrial manager, they can go literally where no rover has gone before.

The prototypes have a unique intelligent navigation system which enables them to plot their own course.

Such is the distance between the planets, it can take 20 minutes for an instruction sent from Earth to arrive at Mars. The delay means instant commands to change direction are not possible and so a rover must have autonomy to make decisions if, for example, it is approaching a dangerous precipice.

And because the rover will make its own decisions, it can also cover more ground."

Wonder how good it would be as a challenge vehicle? (650million euro's)

Or is it double that ? It will have taken 20minutes for the video image to arrive to control centre, then 20 minutes + operator delay for the resulting command to have got back to the Rover... A lot can go wrong in 40 minutes, even at snail's pace :blink:

Just makes you realise quite how complex these things are, not quite the same as a little remote control car, and that's not taking environmental conditions into account.

Sure its complex, but large projects like this, often publicly funded, tend to absorb man hours and funding at a disproportionate rate.

Whatever the budget, it'll get used, whatever the man hours available, they'll want more.

The conditions aren't so bad - lower pressure means the normally alarmingly high wind speeds are not so bad (lower dynamic pressure).

Lara - probably weight and reliability.

Al.
