“…These have been used for tasks like coffee types classification (Gardner et al, 1992). Ionic polymer metal composite (Zhao et al, 2023) sensors were also used for E‐tongue construction (Das et al, 2023), which was then used to detect milk adulteration (Pal et al, 2023), but their selectivity is unclear, measurement times too long, and their use for robotic chefs is questionable. Other types of sensors can be used too (Yamaguchi, 2021).…”

Robotic chefs are a promising technology that can improve the availability of quality food by reducing the time required for cooking, therefore decreasing food's overall cost. This paper clarifies and structures design and benchmarking rules in this new area of research, and provides a comprehensive review of technologies suitable for the construction of cooking robots. The diner is an ultimate judge of the cooking outcome, therefore we put focus on explaining human food preferences and perception of taste and ways to use them for control. Mechanical design of robotic chefs at a practically low cost remains the challenge, but some recently published gripper designs as well as whole robotic systems show the use of cheap materials or off‐the‐shelf components. Moreover, technologies like taste sensing, machine learning, and computer vision are making their way into robotic cooking enabling smart sensing and therefore improving controllability and autonomy. Furthermore, objective assessment of taste and food palatability is a challenge even for trained humans, therefore the paper provides a list of procedures for benchmarking the robot's tasting and cooking abilities. The paper is written from the point of view of a researcher or engineer building a practical robotic system, therefore there is a strong priority for solutions and technologies that are proven, robust and self‐contained enough to be a part of a larger system.

“…As an electroactive polymer, it is capable of producing a direct mechanical response when driven by an applied electric field, which is similar to the phenomenon of biological muscles, hence IPMC is also known as artificial muscle. And thus it has significant advantages in simulating biological muscle movements [4][5][6]. The material has a low driving voltage and is capable of producing bending deformations at a few volts, and its fast response, low energy consumption, and light weight make it suitable for miniaturized and miniaturized application scenarios [7][8][9][10].…”

Ionic polymer-metal composite (IPMC) actuators have attracted considerable scientific interest in the field of robotics and artificial muscles due to their low operating voltage, high strain capacity, and lightweight. However, the non-uniform bending of IPMC actuators affects their control accuracy and limits their potential applications. In this work, the surface voltage of IPMC actuators was measured and the internal electric field distribution was numerically computed. It was concluded that the non-uniform bending is mainly due to the non-uniform distribution of hydrated cations inside the IPMC as a result of the inhomogeneous electric field. The bending uniformity is improved by sputtering a gold layer on the surface of the IPMC actuator, and a support strip is introduced to limit the bending of the IPMC in the width direction, resulting in an improvement of its pointing characteristics. It is found that the bending uniformity of IPMC improved by 108.32% and 220.63% by sputtering at an input voltage of 2.5V and 5V respectively. When the input voltage is fixed at 2.5V and 5V, the bending in the width direction is reduced by 92.31% and 95.17% with the support structure, respectively.
