Spatial cell robot based on gear and gear rack transmission

Abstract

The invention relates to a spatial cell robot based on gear and gear rack transmission. The spatial cell robot comprises sliding blocks, a cross guide rail, guide rail supporting rods, a supporting plate, four groups of guide rail assemblies, a grooved bevel gear, an incomplete bevel gear, a servo motor, a gear rack, a shell end cover, a transmission shaft, an incomplete cylindrical gear and the like, wherein the incomplete cylindrical gear and incomplete bevel gear are driven by the serve motor to rotate synchronously; meanwhile, the gear rack is driven to move; then, the cross guide rail connected with the gear rack is pushed to move forward and the guide rail assemblies are pushed to move forward, so that the linear driving work can be completed; when the toothed part of the incompletebevel gear is meshed with the grooved bevel gear, the guide rail assemblies radially move along a groove of the shell end cover, so that the rotary driving work can be completed; and when two connected spatial cell robots are disconnected, the servo motor rotates reversely, the incomplete cylindrical gear and the gear rack jointly act, and the guide rail assemblies begin to retract and return to initial positions, so that the spatial cell robot separating and disconnecting work can be completed.

Description

technical field [0001] The invention relates to a space cell robot mechanism based on rack and pinion transmission. Background technique [0002] Since the 1990s, self-reconfigurable robots have developed rapidly in the United States and Japan. Connection mechanisms are the key components of self-reconfigurable robot cell modules. Self-reconfigurable robots based on different connection methods have the stability and Security is all different. At present, the existing self-reconfigurable robots in China mainly use electromagnetic, memory alloy and mechanical connection mechanisms. Due to the large size of the electromagnetic connection mechanism, poor shear resistance, high heat generation, and difficulty in reconfiguration and movement in a magnetic environment, although the memory alloy is small in size, it consumes a lot of energy, and it is difficult to adapt to the environment of the module's own power supply.
