Technical Background and Objectives
Background
In the field of ‘robotic arms’ technology, the technical effect of ‘robotic arm simple structure’ has seen a steady increase in patent applications over the years. This upward trend reflects the growing interest and investment in simpler, efficient robotic arm designs. This movement is potentially spurred by cost reduction, manufacturing ease, and improved versatility.
Contrastingly, the literature publication data shows a more volatile pattern. Initial growth was followed by a decline, then a recent revival. This fluctuation may stem from research maturation, focus shifts, or new challenges/opportunities sparking academic interest. Despite these variations, the consistent patent filing rise indicates a robust industry motivation to develop simplified robotic arms.
Objectives
The primary objective is to develop a simple and cost-effective robotic arm structure. This trend could be driven by the growing demand for robotic solutions across various sectors, including manufacturing, healthcare, and service industries, where simplicity and cost-effectiveness are desirable attributes.
