We designed and demonstrated a single-legged or unipedal walker that has a "cleat" that allows it to persistently associate with a track and make autonomous decisions about movement. The walker is highly processive over long periods of time, as shown by its movement over a microparticle surface suffused with substrate. The simple design can be readily optimized on the basis of simple energetic considerations. The walker can be used for signal amplification and should prove especially valuable for programming amorphous computations within chemical reaction networks.
