Abstract:Whiskers are very common features for animals; they are present in almost allmammals. There are various applications which would benefit from being able to mimic these whiskers. The specific application that will be discussed within this paper is the use of whiskers as a tactile force sensor. The systemwill be passive andwill measure the force and distance atwhich a force is applied. The end goal of the sensor is to have the ability to measure 4 degrees of freedom. A more simple version of a tactile whisker sensor consisting of 2 DOF will be considered first. Within this report, the focus lies on creating amechanical analysis of the system and simulating the behaviour of the whisker. The mechanical analysis of the whisker was then compared to the Ansys simulation of the whisker. The results of the comparison of the mechanical analysis and the simulation of the whisker lie close to each other, meaning that the whisker behaviour derived from the mechanical analysis in this report can be used in the future. Especially the 4 DOF mechanical model shows a lot of similarities with the simulations.
