This article presents a review of work related to therapies and tools used in fine motor stimulation in order to establish the parameters and characteristics necessary to define the creation of an interactive board with 5 different activities as an alternative therapy proposal. This board is implemented as a tool that serves as a support for therapists in sessions of fine motor stimulation in order to innovate in traditional therapies. This is possible since it is known that the use of technology allows us to create attractive and fun tools for children, who show more attention and dedication when interacting with a tool as if it were a toy. This tool is created with the intention of transforming stimulation therapies into fun gaming sessions in order to get children to carry out activities that help strengthen and stimulate the muscles necessary for correct development in their daily and school activities, which involve a digital grip, tri-digital grip, strength in the fingers and hands, hand-eye coordination, assimilation of request for activities by audios and finally motivational feedback in case children fail and positive feedback in the case of finishing the activity correctly. For therapists these tools are the fundamental basis of the sessions; that is why innovation plays a key role since the more interactive and attractive sessions, the greater openness to the experience, which originates better results.

This paper presents a performance evaluation of the development of the instrumentation, communications and control systems of a two-tank process by using low-cost hardware and open source software. The hardware used for automating this process consists of embedded platforms (Arduino and Raspberry Pi) integrated into programmable logic controllers (PLCs), which are connected to a supervisory control and data acquisition (SCADA) system implemented with an open source Industrial Internet of Things (IIoT) platform. The main purpose of the proposed approach is to evaluate low-cost automation solutions (hardware and software) within the framework of modern industry requirements in order to determine whether these technologies could be enabling factors of IIoT. The proposed control strategy for regulating tank levels combines the classic PID algorithm and the fuzzy gain scheduling PID (FGS-PID) approach. Fault detection capabilities are also enabled for the system through a fault detection and diagnosis module (FDD) implemented with an extended Kalman filter (EKF). The distributed controller&rsquo, s (DC) algorithms are embedded into the PLC&rsquo, s processors in order to demonstrate the flexibility of the proposed system. Additionally, a remote human to machine interface (HMI) is deployed through a web client of the IIoT application. Experimental results show the proper operation of the overall system.
