These plastic soles are an upgrade for Kondo's KHR-1 and KHR-2HV
humanoid robots. Tub soles allow for smoother walking gaits. If you
are purchasing the
Genex Suit for the KHR-2HV, these soles are required.
Tub soles are
included in the KHR-1HV kit, so if you're purchasing a 1HV, you don't need
these.
