Metal???

it will be really, really hard, neigh imposibe to have 4wd and a wepon and efective armour.

Baby Hell fits that catagory: 4WD, an axe and 6mm HDPE and 0.5mm Titanium armour, and an 11.1v battery to boot. I finished it this evening, and its 152g, but thats within tolerance, and I can bring the weight down by changing the axe arm, so its possible, but, as Haz said, very hard.

i know that but 4wd and a spinner would be harder to get efective.

how could it possible be that light???????
are they micro gear motors

[harry hills]

well yes of cource, nearly all ants use them

[razerdave]

I think he means things like pager motors, which I have seen used but are terrible. I think you can get 4WD and a bar spinner into 150g, you would just need specialist bits and a very compact robot.

[archie2000]

easier said than done

[harry hills]

either go good 4wd or good 2wd and wepon, i think the only effective 4wd with a wepon is baby hell

thats agreeded
