i think no. robots are only machines... if they are out of control... they can perform unwanted behavior... which is harmful to the human species... so giving weapons to robots is not an appropriate option.
yes
cool computer, but rcoitobs? come on. this costs $250. killing a fly with a hand grenade. wtf? i'm wondering if it has *enough* cpu to do anything useful, and you're already implying it has *too much*? hate to break it to you, but rcoitobs will eat up all the cpu power you can throw at it. try doing vision, kinematics, motion planning, ai, etc. on-board a robot and see how far you get.
