Abstract

Today, both Direct Current (DC) and Alternating Current (AC) motors are utilized in many different applications in a variety of sectors. Such applications in the automobile and domestic sectors provide the energy required to generate mechanical power. The mechanical utilities such as winches, garbage compactors, auto walks, and elevator shafts use motor power to provide functional mobility at variable speed ranges adjusted as required [1] [2]. However, the mechanism to control motors is not ‘smart,’ as is the case in different electronic applications of today that are controlled by the mechanism of Application Programming Interfaces (APIs) [3] [4]. The listed examples still make use of analog functionalities, i.e., levers and pushbuttons. In the garbage compactor application, controlling the motor uses pushbuttons in the cabin, and, also the levers at the back of the truck. Operating the machine is tedious for the driver or the loader in that they must leave the cabin to operate the auxiliary machine each time. The process is labor-intensive with additional health hazards of having to deal with bad odor from the waste material. There is also an increased risk of physical injury, exposure to dangerous diseases from the dirty working environment; such as cholera and diarrhea as well as exposure to novel viruses not yet known in the medical field. Cases in point include exposure to Severe Acute Respiratory Syndrome (SARS) and Covid-19 [5]. In addition to the health hazards inherent in the manual application of the winch machine, the operator faces a further challenge of not being able to keep the back of the truck within the line of sight. The operator has to focus on the operating buttons in the cabin while at the same time trying to manage the auxiliary functionalities at the back.
