Flexible machines have become increasingly important in fields that require precise automation, such as automotive and aerospace industries. As such, there is a need to further increase the flexibility of existing flexible machines. This paper presents an overview of techniques and methods that can be used to improve the flexibility of such machines.
The first step in improving the flexibility of a machine is to determine what components and features need to be upgraded in order to achieve the desired level of flexibility. Common features that need to be upgraded include the mechanical structural layout, the wiring, and the physical and electrical components. In particular, when modifying the mechanical structural layout, the critical components and connections must be examined for strength, stiffness, and stability. Wiring changes must also be made to ensure that electrical signals are sent from the machine controllers to the necessary components. Finally, changes to the physical and electrical components are necessary, such as the detailed design of cams and the installation of additional switches and sensors.
In addition to the mechanical and electrical changes, the control system of the machine must also be updated in order to achieve the desired flexibility. This involves implementing advanced control algorithms and understanding how they work in order to provide precise commands to the actuators and intelligently manage the system. Some of the algorithms that can be used to improve flexibility of a machine include fuzzy logic control, artificial neural networks, evolutionary algorithms, and multiple optimization approaches.
Finally, it is also important to consider how the machine will interact with its environment. If a machine is to operate in a cluttered environment with many obstacles or in extreme temperatures or conditions, the control system must be able to respond appropriately. This typically involves implementing sensor fusion algorithms, which combine multiple types of sensor data in order to provide the control system with precise and detailed information about the surrounding environment.
Overall, with the proper combination of changes to the mechanical and electrical components, the control system algorithms, and the machines interaction with its environment, it is possible to significantly increase the flexibility of a machine. Doing so will enable the machine to better meet the demands of the industry that it is intended for, as it will be able to perform a larger variety of tasks more efficiently.
