In minimally invasive surgeries, robotic technology is employed to manipulate medical instruments to reach target locations for diagnosis and treatment. It is challenging to eliminate collisions or contact between medical instruments and tissues, which increases the risk of complications for patients and limits the scope of many surgeries. This paper proposes a morph-adaptive catheter that combines magnetic deformation control with the solid-liquid phase transition capability of low-melting-point alloys. This enables the catheter to navigate around avoidance tissues and reach the target location without collisions or contact. Theoretical calculations have preliminarily verified the consistency between the expected and actual deformations, and experiments have initially demonstrated the feasibility of the proposed morph-adaptive catheter for contactless operation. This approach offers a new method to reduce tissue damage from instruments and enhance the safety of surgeries in minimally invasive surgeries.

Visual servoing represents a control strategy capable of driving dynamical systems from the current to the desired pose, when the only available information is the images generated at both poses. In this work, we analyze vulnerability of such systems and introduce two types of attacks to deceive visual servoing controller within a wheeled mobile robotic system. The attack goal is to alter the visual servoing procedure in such a way that mobile robot achieves the pose defined by an attacker instead of the desired one. Specifically, the attacks exploit image transformations developed using a methodology based on simulated annealing. The main difference between the attacks is the considered threat model - i.e., how the attacker has infiltrated the system. The first attack assumes the real-time camera feed has been compromised and thus, the images from the current pose are modified (e.g., during the acquisition or communication);for the second, only the desired destination image is potentially altered. Finally, in 3D simulations and real-world experiments, we show the effectiveness of cyber-attacks.
