“…It may not suitable for real-time implementation since the manufacturing of the desired size belt is difficult. Stretcher cum wheelchair robot is proposed by Sang et al, (2020) but, the weight and bulkiness of the modal are not addressed. The concept of a spoke wheel with a direct drive hub motor was discussed Avutu et al, (2019).…”

The wheelchair is the primary rehabilitation device used to enable the movement capability of disabled people. To provide an appropriate wheelchair, the doctor will suggest the necessary customization has to be made on the existing one. However, the customization of a manual wheelchair is easy and cost-effective compared with the powered wheelchair due to simple structure and spare parts availability in the market... Because of the above, a novel concept is proposed. The rear wheels of the manual wheelchair are replaced with a Direct drive motor alloy wheel. CATIA – V5 is utilized to design the proposed wheel and ANSYS software is used to check its performance at different load conditions. The stress-bearing capability of different materials for various Direct drive motor weights is observed through structural analysis. The natural mode frequencies are found using modal analysis and its nature of vibrations is verified. The harmonic response analysis is used to test the nature of deformation and stress concerning natural frequencies for the applied force.

“…The most important function of optocoupler relay is isolation. Its function is to prevent strong current from entering weak current in series, so as to protect STM32 from damage [24]. When starting the device, the WeChat Applet sends "1" to a STM32, which receives the signal and sends it to the device to be started after processing.…”

The Industrial Internet of Things (IIoT) is of great significance to the improvement of industrial efficiency and quality, and to reduce industrial costs and resources. However, there are few openly-reported practical project applications based on the IIoT up to now. For legacy automation devices in traditional industry, it is especially challenging to realize the upgrading of industrial automation adopting the IIoT technology with less investment. Based on the practical engineering experience, this paper introduces the automation renovation of a sewage treatment plant. The legacy automation devices are upgraded by the central controller of a STM32 processor (Produced by STMicroelectronics company, located in Geneva, Switzerland), and the WeChatApplet (Developed by Tencent company, located in Shenzhen, China) is used as the extended host computer. A set of remote monitoring and control systems of sewage treatment based on the IIoT is built to realize the wide-area monitoring and control of sewage treatment. The paper describes the field hardware system, wide-area monitoring and control application program, management cloud platform and security technologies in detail. The actual operation results show that the monitoring system has the requirements of high accuracy, good real-time performance, reliable operation and low cost.

“…This type of structure changes the angle between the chair seat and the back of the wheelchair through the telescopic change in the length of the connecting rod in order to achieve posture adjustment. The connection mode of the series connecting rod structure is relatively simple, and the technology of the main parts is relatively mature and can meet the needs of some disabled people [ 25 , 26 ]. However, the series connecting rod structure is unstable and may shake in the standing state, which can be a source of fear for the user [ 27 ].…”

Due to the fixed size of the structure or the possibility of only simple manual adjustment, the traditional toilet wheelchair cannot easily be adapted to the size of the user or the toilet. In this paper, a planar two-degree-of-freedom parallel mechanism with coupling branch chains is proposed to enable both seat height adjustment and body posture adjustment of a toilet chair, solving the problems of posture adaptability between the user and the machine, and height matching in the process of using the wheelchair-assisted toilet. The model of the parallel mechanism was designed after analyzing the general rules of posture transformation in the human body before and after the toilet process, and the dimensions of each linkage were then determined according to the constraint conditions. By analyzing the degree of freedom, kinematics, workspace, singularity and position of the center of gravity, the rationality of the design was ensured. The weighted average function was used to find the optimal fixed point of the horizontal moving slider, and the actual trajectory at the end of the single driving mode was close to the ideal trajectory. The experimental results show that the adjustable seat height range is 290~550 mm and the adjustable angle range is 0~90°, which can enable disabled people to use the toilet independently.
