Flexibility and speed in the development of new industrial machines are essential factors for the success of capital goods industries. When assembling a printed circuit board (PCB), since all the components are surface mounted devices (SMD), the whole process is automatic. However, in many PCBs, it is necessary to place components that are not SMDs, called pin through hole components (PTH), having to be inserted manually, which leads to delays in the production line. This work proposes and validates a prototype work cell based on a collaborative robot and vision systems whose objective is to insert these components in a completely autonomous or semi-autonomous way. Different tests were made to validate this work cell, showing the correct implementation and the possibility of replacing the human worker on this PCB assembly task.
The Digital Twin approach has increased in interest in recent years. Without well defined specifications, it is common for different researchers to use different approaches. Digital Twin concept emerged to support Industry 4.0, so it is of utmost importance to specify a best methodology, and tools, for its implementation for industrial use cases. This work proposes a Digital Twin architecture that follows manufacturingcentric standards of an industrial prototype testing station, for a new car infotainment system. Testing is performed by low-cost Software-Defined Radio equipment that aims to replace expensive metrological equipment. Moreover, an environment sensing device is also used to monitor the physical environment around prototype. We present the development of a solution that allows manage hardware processing, real-time monitoring of machine states in the virtual environment, and control of the overall system through a logical sequence supported by its Digital Twin. With the implementation of a standard like ISO23247, helps in the identified problem of having various Digital Twins and improves an interaction with test equipment. All steps made for the development of our architecture approach, as well as some results, are shown and explained for our use case.
The research and development of new kinds of technologies to support the recovery of human injuries have orientated the design, development and construction of new devices for the treatment and rehabilitation of wrist injuries. With limited founds, the construction of a new prototype was carried out with off-the-shelf components. After a detailed research and design work, the obtained device can be divided into two main components: it is capable to provide an adequate rehabilitation of the wrist and adequate proprioception exercises, allowing the patient to relax and to decrease the focus of pain.
The development and construction of the device upholds the idea of portability, multifunctional operation and special designed hardware and software control, so it can be simple and user-friendly, allowing the control over the progress of rehabilitation with data recording for later analysis by physiotherapists and/or patients without any special training. The mentioned multifunctional operation, low-cost, user-friendly and portability makes it a good choice when compared to other complex robotic rehabilitation devices.
This paper will present, discuss and analyse the proposed portable device, as well as its ability for the purpose of wrist rehabilitation.
