nonweight and usable

[greencactus3]

we need to cover up our electronics. NEED TO.
they are at a very accesible place on our robot. VERY accesible
accessible to balls and other robots.. and we are VERY close on weight.
and we still have a couple more subsystems we want to add. such as something to knock the 10pt ball off... to latch onto the mobile goal.... possibly even hang.(dont think we'll get to that yet....
but im thinking covering the electronics is our top priority.
right now, weight-wise, im thinking a net of some sort.... and hope it wont catch other robots... especially since we cant take home what we catch...
but plexiglass is too heavy...
what should we use?

another thing....on our plow.... we took off a lot of things that worked to push the balls without going over them... cuz we were overweight...
what is the lightest way to ensure we won't run over the balls, and will push the balls easily?
we do not want to run over any balls.. we are using 12in wheels...
