Abstract
A sealed joint module is for use in association with an arm element of a robotic arm. The arm element may be a link, a seat, a payload interface or the like. The sealed joint module includes a module housing, a hollow joint assembly and a sealing assembly. The hollow joint assembly is operably attached to the module housing. The arm element is operably attachable to the hollow joint assembly. The sealing assembly is operably attached to the joint and to the module housing. The sealing assembly includes a dynamic sealing component between the arm element and the actuator assembly. A modular robot arm includes at least two sealed joint modules and at least one link.
