RESEARCH OF THE CHARACTERISTICS OF A FORCE SENSOR BASED ON THE VELOSTAT MATERIAL FOR A MOBILE WALKING ROBOT
The paper presents a piezoresistive tactile transducer designed for use in the tactile sensing system of a mobile walking robot. Haptic sensing is especially relevant for vehicles moving in enclosed space under conditions of lack of visibility. In the study, experimental studies of the transducer's operation were conducted at a load area smaller than the size of the transducer itself, which simulates the conditions of contact of the walking robot's legs with a rigid supporting surface. According to the results of the experimental studies, it is shown under which conditions the transducer characteristics satisfy the requirements for the tactile perception system of a walking robot.
