A six-wheel exploration rover, drawn as a live engineering sheet. It is driving itself between survey targets over procedural terrain: scanning the ground, rating it against what the vehicle can climb, and steering round what it cannot. Every number on the sheet is either a constant the simulation runs on or a measurement of the model.

THINGS TO TRY

• Change the ground: the channel makes it find a ramp down and another up, the yardangs make it run with the grain, the lava flow never lets a wheel rest.
• Launch the scout on the dunes and watch it map the way ahead.
• Switch the LiDAR off, then step the clock on to night and find out what the floodlights are for.
• Arm the solar wings and shut the reactor down: the vehicle parks across the sun and the sols go by.
• Fold the radiator wings and see how much the reactor can still give.
