This Lego claw machine has been built using a single motor and a set of mechanical linkages to replicate the operation of traditional arcade claw games. The design uses Lego Technic elements and a single electric motor to control the claw’s horizontal travel, vertical descent and grip action through a series of gears, cams and articulated connections. The mechanism demonstrates how constrained input can be translated into multiple coordinated motions.
The claw assembly is mounted within a frame constructed from Lego beams and connectors. Motion from the motor is routed through gear trains and lifted cam profiles that drive the claw’s movement along configured axes. The grip action engages when specific linkage positions are reached, allowing the claw to pick up and release objects without additional actuators.
