Fabrication of Flexible Drilling Machine by Remote Control

The fabrication of a flexible drilling machine operated by remote control is presented in this work to address the limitations of conventional stationary drilling systems. Traditional drilling machines require frequent repositioning of the work piece to achieve different drilling angles, which increases operational time, labour effort, and the possibility of errors. The proposed system integrates mobility and articulated arm movement to enable drilling operations at multiple orientations without relocating the work piece. The developed prototype consists of a wheeled base for easy mobility, a vertical support column housing a battery and control unit, and a robotic arm mechanism driven by a servo motor. The arm assembly includes vertical and horizontal links connected through a four-bar linkage arrangement, providing stable and precise positioning of the drill head. A DC motor mounted at the arm’s end drives the drill bit to perform the drilling operation. The entire system is remotely controlled, enhancing operator safety and improving accuracy in drilling tasks. This flexible drilling machine is particularly suitable for applications involving large, irregular, or hard-to-reach work pieces in industries such as construction, automotive maintenance, and aerospace servicing. The prototype demonstrates improved flexibility, portability, and efficiency compared to conventional drilling methods. The study concludes that the proposed system offers a practical and cost-effective solution for automated drilling, with future scope for integration of sensors, CNC control, and IoT technologies to further enhance performance and intelligence.
