Abstract

The invention relates to a micro-robot mechanism, concretely relating to a variable-diameter crawler-type robot mechanism used for colon diagnoses and examinations. Therefore, problems of a conventional micro-robot mechanism used for colon diagnoses and examinations are resolved. Such problems include low execution efficiency and the failure of fulfilling functions of varying diameters and lingering. The variable-diameter crawler-type robot mechanism used for colon diagnoses and examinations comprises a variable-diameter sub-mechanism and three walking sub-mechanisms. The variable-diameter sub-mechanism comprises a front baffle board, a back baffle board, a first direct current motor, a driving gear, a lead screw, a driven gear, a front nut, a back nut, three guide rods and three four-barlinkage mechanisms. Each walking sub-mechanism comprises a cabinet, a second direct current motor, a driving bevel wheel, a left bearing, a right bearing, a rotating shaft, a left synchronous pulley,a right synchronous pulley, a driven bevel wheel, a left resistance-decreasing roller, a right resistance-decreasing roller, a left crawler belt, a right crawler belt and an ear board. The variable-diameter crawler-type robot mechanism used for colon diagnoses and examinations is suitable for noninvasive diagnoses and examinations of colon diseases.

Description

technical field [0001] The invention relates to a micro-robot mechanism for colon diagnosis and examination, in particular to a variable-diameter crawler-type robot mechanism for colon diagnosis and examination. Background technique [0002] The micro-robot mechanism for colon diagnosis is a micro-robot mechanism that can actively move in the colon, which is considered to be the most promising device for non-invasive diagnosis of colon diseases. Under the existing technical conditions, there are mainly two types of micro-robot mechanisms for colon diagnosis: the first type is an inchworm-like micro-robot mechanism. This kind of micro-robot mechanism uses a peristaltic pump to inflate and inhale the airbag to achieve two-way movement, variable diameter and residence functions. ), resulting in low efficiency of its action execution, thus affecting the efficiency of diagnosis and examination. The second is crawler micro-robot mechanism. The problem with this kind of micro-ro...
