i have some robot models, but they are not in poser format, they are just single mesh static models.. if you know anything about boneing them in poser then there are lots of models out there for you.. there are many very low poly models from games like quake at planetquake, planetunreal, planethalflife..etc.. i have converted these to poser before. though they will take some editing in a modeling program like max or milkshape if you dont use max..
