Abstract
A rocking arm structure includes an arm body, a motive wheel assembly connected to the arm body, a caster wheel assembly connected to the arm body, and a shaft assembly connected to the arm body and disposed between the motive wheel assembly and the caster wheel assembly. The two wheel assemblies are configured to revolve in a same direction around the shaft assembly and for example allow a 4-wheeled vehicle/robot to become a 6-wheeled vehicle for stability as required during changes of terrain.
