Polishing is an indispensable basic process in manufacturing. As large and heavy as machinery and automobiles, and as small as mobile phones and home appliances, grinding and polishing is a necessary step to render product smooth or glossy; It is due to prevalence of grinding and polishing procedures can items with a high-value appearance be seen everywhere in our daily life.

However, behind the attracting product appearance is the painstaking work of numerous workers in the industry. Years of job grinding metal materials can lead to work-related injuries such as joint and lung diseases. In extreme cases, dangerous situations like explosion accidents caused by the metal dust from grinding occurs. Intensity workload and harsh working environment have led to a sharp decrease in the number of employees in the grinding and polishing industry, and the phenomenon of "difficulty in recruiting workers" spreads. In addition, manual polishing is criticized for its low efficiency and lack of quality consistency. Various factors are driving the quest for robotics and automation solutions.
