@PaulHammond51 what was changed in the driving mode?

@micmol

Here is a good summary of the issue and how they fixed it by modifying the driving algorithm.

@PaulHammond51 Highly interesting. I am assuming it has encountered far less hostile terrain?

PaulHammond51, 11 months ago

@self They have avoided some of the worst terrain. The Greenheugh Pediment was bad, the terrain there was dubbed "gator-backed". Here's a blog where the geology team talk about avoiding the worst of the terrain but ensuring they reach the science waypoints https://mars.nasa.gov/msl/mission-updates/sol-2032-2033-the-rocks-vs-stone-cold-aluminum-wheels/

The rover recently drove out of Marker Band Valley, they had numerous failed drives due to the difficult terrain, I honestly expected this wheel check to reveal a lot more damage, but it has held up remarkably well.

@PaulHammond51 They should have used Duranium. #NASA could have easily got Duranium from the Andorians, Cardassians, Ferengi, Humans, Klingons, or the Trabe.

@PaulHammond51 wonder what's the kind of change to the driving algo. Less reckless driving? Obstacle avoidance?

Here's a summary about the changes to the driving algorithm:

https://mars.nasa.gov/news/an-algorithm-helps-protect-mars-curiositys-wheels/

TL:DR The revised traction control algorithm uses real-time data to adjust each wheel's speed, reducing pressure from the rocks. The software measures changes to the suspension system to figure out the contact points of each wheel. Then, it calculates the correct speed to avoid slippage, improving the rover's traction, and preventing damage.
