Skookumjim Posted January 27, 2021 Posted January 27, 2021 I have for a while wondered about using robotic components to automate/control the Lego Rough Terrain Crane ... this has now happened using the Mindstorms Robot Inventor hub with 5 medium stepper motors and a distance sensor ....while keeping the original power functions large motor to avoid further destruction of the original model. One motor switches turntable rotation, another switches the drive from turntable to jib while a third switches power to the original motor. Two further motors switch the six way gear selector for hook and jib. the distance sensor is used to limit turntable rotation to accommodate the relatively short cable lengths. The resulting construction works well.... the crane can both remote controlled and programmed. https://www.dropbox.com/sh/82vqyjvd2zledp0/AAA736uPmlzo9hL-sIWdGS8la?dl=0 Quote
