Neat idea! But what makes you think that graphene super capacitors are the best option? Why not some combination with solar battery(if it's going to fly outside) or some other kind of energy source?
Because the relation weight/power its outstanding. well i don't think using solar could help at all,because it will make the robot heavier and it will need a big area in order to power up the robot which for this type of robots its not possible i think, and also unless solar cells improve their energy efficiency this doesnt sound possible yet.
