“…The elastic structure of the F/T sensor detects surface strains due to force acting on the sensor and provides several detection points with large surface strains for each force and torque in the x-, y-, and, z-directions. To overcome the reliability degradation of our previous elastic structure designs, we used a newly designed elastic one-body structure with several detection points and big surface strains [20]. The applied force in the x-or y-direction affects vertical beams, whereas the applied torque in the z-direction affects horizontal beams.…”

Six-axis force/torque (F/T) sensors have been actively developed owing to the increasing demand for force control and monitoring in many engineering applications. However, these sensors are expensive and complicated to use, particularly the wireless ones. This study presents a userfriendly and economical wireless six-axis F/T sensor for force control and monitoring applications. A newly designed elastic structure was used to overcome the reliability degradation and high machining cost problems of the elastic structures developed in our previous study. T-shaped structures were arranged symmetrically around the upper and lower parts, reducing the manufacturing cost. The electrical and electronic circuits for economical analog/digital signal processing, including zero calibration, were developed based on cheap microcontrollers. A user-friendly embedded wireless communication module was programmed at a low machine level for fast force control and monitoring. Additionally, we implemented a universal serial bus (USB)-wired F/T sensor similar to the wireless unit, except for wired communication. The effectiveness of the proposed F/T sensor was demonstrated by experimental tests and comparison with a commercial F/T sensor.
