This paper presents the design and construction of a single-arm crane in a reduced form, as an instructive model to understand its working and control principles. The model uses an arm length of 70 cm, representing a reduction scale of 1:100 of its actual size. The assigned maximum load was 2.5 kg, considering the availability of mechanical structure materials. A separately excited direct-current motor was chosen based on the requirements of load-torque characteristics and considering its ease of control and availability. The designed miniature crane uses 3 motors of 20.844W, 11.256W, and 10.81W to manoeuver the crane, i.e. to drive the boom, to tow the rope, and to rotate the crane respectively. The motors were driven using a MOSFET converter, whereas its trigger control was facilitated using a microcontroller. The experiment results indicated the ability of the crane miniature to move the load as previously determined in the specifications. © 2017 IEEE.
