Foot-drill is a research area that focuses on the biomechanics and performance of mechanisms designed to be operated by human foot power. This research area explores how humans can efficiently and effectively power machines and devices through the use of foot movements. Foot-drill research can encompass a variety of applications, from manual tools and equipment for agricultural or construction purposes to exercise machines and recreational devices. The goal of foot-drill research is to improve the design and operation of foot-powered systems to optimize performance and user experience.
