Abstract


The symmetrical 7-PR(RRRR)RP seven-bar linkage and the 4-RRRP four-bar linkage are compared in this study to determine which is more feasible for the design and development of a medical disinfection robot with a folding mechanism structure. In order to perform sanitation procedures in the hard-to-reach places from various medical facilities, the optimal solution should allow the greatest variation of the mechanism's total height between folded position (which is considered to be the minimum configuration) and the extended position (which is considered to be the maximum configuration), while simultaneously maintaining the robot's size as small as possible.
