Dynamic, biped walking is a difficult motor coordination problem for robots. "RunBot," shown here, contains two joint motors and two hip motors and an upper-body component. These actuators are dynamically controlled by a neural network that can adapt via simulated synaptic plasticity to novel situations, such as a change in the terrain. This way, RunBot's walking pattern looks rather human-like (see Video S2 5.1 MPG), and the little machine successfully tackles difficult walking situations (see Manoonpong et al, e134).
