I see, I might rethink that plan then. Had no idea flippers were that powerful for one, and it sounds like the downsides of using enough magnets to retrieve satellites from orbit probably outweigh any benefit they may bring, at this level of engineering on my part anyway.

Would it be better to, say, go with much lower levels of downforce over each wheel to help improve grip, or just going for better wheels to get that improvement? All I'm thinking is that my machine, at the moment anyway, is heavily focussed on pushing other robots about, and whilst 4 drills will be able to manage that, I'd not stand a chance up against say, Satanix's beefy drivetrain, or most of the others using the tougher motors... I was debating detachable side skirts like Storm II as well (albeit at the risk of looking suspiciously too similar to it) for when I come up against flippers, but it's the worry of them getting caught between floor panels...
