Well, preorder one, anyway. You might remember Roboquad from Susi's video preview in January this year. He's a four-legged spiderbot from the same people who brought you the very-fine Robosapien.
You can tweak his awareness, activity and aggression levels to suit your plans for taking over the world, he can react to lighting levels, and has all manner of advanced sensors on board. More importantly, he's going to cost £80, and Red5 is taking preorders now.
