Soft robots are constructed of materials which absorb energy and therefore do not harm
people or their environments. Indeed, it is possible that soft elastomer foams may be the best
choice for constructing such a robot because the thin walled lattice that makes up the foam endows
the elastomer with a far greater softness than that of a bulk polymer. Robots whose main structural
components are made from elastomeric foams are under-explored. Several key concepts for
design, manufacturing and control of foam robots are examined in this work and demonstrated by
two motor-tendon actuated polyurethane foam terrestrial robots.
