Transporting and dispensing chemicals from a drum is a common process. The main problems are that the weight of chemicals in a chemical drum makes the transport task difficult, the properties of chemicals are different, and the quantity of chemicals to be dispensed has not been controlled automatically. Thus, the research project aims to develop a vehicle that transports a chemical drum and dispenses chemicals easily and rapidly. Moreover, we can specify the weight of chemicals to be dispensed. The developed vehicle consists of 3 main parts, i.e., a movement unit, a drum lifting and rotating unit, and a chemical dispensing unit. A movement unit was designed to contain a robust base and wheels to support the weight of chemicals. The drum lifting and rotating unit was designed with grabbing arms to tighten a chemical drum to the vehicle. After that, a hydraulic rod was used to lift the chemical drum and then a motor was employed to turn the drum upside down. A dispensing unit was used to dispense chemicals with the help of compressed air until the weight of dispensed chemicals reached the preset value. The chemicals used in evaluating the vehicle were PBTC and AA/AMPS. The experimental results showed that the dispensing rate of PBTC was 30.0 kg/min, while the dispensing rate of AA/AMPS was 16.8 kg/min. Besides, the chemical dispensing error was less than +/–2.8 kg. Therefore, the developed vehicle can facilitate dispensing chemicals, reduce dispensing time, and reduce the labor cost.
