This article describes a means for sensing an incorrect position of a robot gripper during operation. Thereby, conductive rubber is used as the sensitive material, utilizing its pressure dependent resistivity. When a robot handles small and delicate objects, it can easily happen that the object in question, due to misalignment, touches or strikes against undesired areas. If the object is, e.g., a terminal of a cable that is to be inserted in a housing, it can easily bend away from its desired position, which may necessitate undesired manual interference. Thus, there exists a need for a means to avoid such forceful contact between objects operated on. In the prior art one finds various solutions to this kind of problem.
