Uniped
Uniped is a term used in biomechanics and robotics to denote a person or device that uses a single leg for locomotion. The word combines un- meaning one and pes (foot), reflecting the primary feature of single-leg movement. In biological contexts, true unipedal organisms are extremely rare. Most documented cases involve individuals with a single supporting limb due to congenital limb deficiency or traumatic amputation. Locomotion under these conditions must address substantial balance challenges, asymmetric gait, and increased energy expenditure, often requiring assistive devices or rehabilitation.
In robotics and prosthetics, uniped locomotion is an active area of study. Researchers examine single-leg stability,
Applications include rehabilitation devices for individuals with leg loss, as well as laboratory prototypes of legged
