I, personally, don’t care if the dammed things clunk around here but…
Podkayne’s kids like to gather the things up and play with them, Tars Tarkas thinks they make fine targets for radium rifle practice, and the calots get off on shaking and tossing them around like rag dolls.
I suggest that your resources would be better spent on developing some mini-submarines to explore Venus. The natives there are always very intense about doing what they do best, and will likely ignore your silly machines.
The problem, it seems, is that those bloody Martians don´t respect the probes we send, “Oportunity”? “Spirit”? what kind hippy crap is that? no sirs, what we got to do is call the next one Sam Parkhill, they´ll soil their pants and run for the hills.
