Domus, a House-Bot

More grinding noises came from down below, and their stable patch of roadway skewed sickeningly around. The two humans scrambled on all fours to the railing. Ken looked down and saw a wavering pyramid composed of scores of octopoid bots. A living metal ladder braced vicariously against the concrete road bed. As soon as he got a leg over the railing, Ken felt metal limbs wrapping around his shoes and ankles. By the time they reached the ground, the two humans were encased in a mass of 50 octopoids.
