27,28,29,30,31,32], control of the robotic fish enabled by IPMC has rarely been studied based on our best knowledge. The possible reason might be lacking of a faithful and practical dynamic model of the robotic fish enabled by IPMC. Due to the complex actuation...
Aquatic animals have developed effective strategies to reduce their body drag over a long period of time. In this work, the influence of the scales of fish on the laminar-to-turbulent transition in the boundary layer is investigated. Arrays of biomimetic

The cooling medium (ethanol: water = 95: 5) was continuously circulated in the double-wall chopping tank to maintain a chopping temperature below 4 °C. All the prepared samples were heated in a constant-temperature water bath at 90 °C for 30 min and then stored at 4 °C for further ...
This was achieved by bubbling a constant flow of premixed air and nitrogen mixture into a 300-l reservoir tank through a stripping column (diameter=4 cm) and monitoring DO twice daily using a DO metre (YSI model 580). Other environmental conditions (temperature, salinity, pH and ammonia ...
All chemical analyses (from each tank) were carried out in triplicate. 4.3. Isolation and Characterization of Carbonated Hydroxyapatite 4.3.1. Isolation of Carbonated Hydroxyapatite from P. Olivaceus P. olivaceus bones were cut into small pieces using a bladed cutter. The bone pieces were boiled ...
All the experiments were performed in the same tank whose dimensions were 970×590×430 mm970×590×430 mm. 3.1. Setup I This setup was used for mapping the motor voltage to the tail beat frequency and for measuring the power requirements. The voltage-to-tail frequency mapping was crucial ...
50% of the tank’s water was replaced daily and promptly supplemented with HA to maintain the experimental doses. Six fish from each treatment group were individually selected and anesthetized using ice [39] to minimize stress after the two-week exposure phase and the subsequent 14-day recovery...
In particular, the circle formation experiments were conducted, where a group of three fish-like robots were randomly placed in the tank initially, and their goal was to form a uniform circle formation while rotating clockwise around a preset target. For this purpose, we adopt a reinforcement ...
