Of what we put on rockets. and then when you land it on the moon, it weighs one sixth of what it does here on earth, right? imagine, like, trying to dig as if you were on ice, right? it will just scoot across the surface. the scoop will not engage and you won't be able to collect anything. so the way the robot scoops up the dust is using this thing called a bucket drum. and it's got a kind of spiral in there. and if it turns it one way, it scoops the soil, which gradually works its way towards the middle and stays there. like that. and then when it wants to unload... ..it turns it the other way and it all comes out again. we put them on opposite ends of the robot and when it excavates, it's using both sets of drums at the same time, but they're digging in opposite directions. so one is pulling it that way and one is pulling it that way... right. ..and pulling itself down to the surface. one of the main dangers faced by extraterrestrial rovers is getting stuck. so, as an added bonus, ipex's scoops and arms can also help it to get out of a hole or flip it over if it takes a tumble. one of its other defences
