Abstract
A new type of screw-based rotary robot actuator, including singular screw-based rotary actuator and double screw-based rotary actuator, is presented and is featured by smaller size, big output moment and compact structure. The principium and mechanism of the new rotary actuator is described in detail. Analysis is given including kinematic design, calculation of capacity of applied load and contact strength of rolling balls. More screw-based rotary actuator can be assembled if needed. Example is given to introduce the manufacturing and analysis
