The movements of motile microorganisms and swimming nanorobots are seemingly random and difficult to predict. I will show how chemically propelled particles move in large circles, flip over on a surface, and slalom through a suspension of spheres. These observations can be explained by a simple theory, which suggests strategies for capturing, filtering, and transporting suspensions of swimmers.
