Introduction • Robotic sensing is a branch of robotics science intended to give robots sensing capabilities, so that robots are more human-like. The experimental results are promising, revealinga linear relationship between the output and the applied load while showing a linear temperaturecharacteristic that suggests temperature compensation will be needed in use. However, these same properties also make the removal of PMMA very difficult. Although the use of haptics in neurosurgical robots is still mostly the domain of research, neurosurgeons who keep abreast of this emerging field will be more prepared to take advantage of it as it becomes more prevalent in operating theaters. Recently, development of instruments for minimally invasive surgery has been considerably required. Compared to laparoscopy, robotics-assisted minimally invasive surgery has the problem of an absence of force feedback, which is important to prevent a breakage of the suture. Congress Series, 1256:337-342. The proposed sensorincludes two key elements, a fiber-optic pressure sensor using a Fabry–Perot interferometer thatwas previously developed by one of the authors and a structure that includes a carbide pin thatcontacts the pressure sensor along the long axis.
